Abstract:

The performance of an optimal-weighted portfolio strategy is evaluated when transaction costs are penalized compared to an equal-weighted portfolio strategy. The optimal allocation weights are found by maximizing a modified Sharpe ratio measure each trading day, where modified refers to the expected return of an asset in this context. The leverage of the investment is determined by a conditional expectation estimate of the number of portfolio assets of the next-coming day. A moving window is used to historically measure the transition probabilities of moving from one state to another within this stochastic count process and this is used as an input to the estimator. It is found that the most accurate estimate is the actual trading day’s number of portfolio assets and this is obtained when the size of the moving window is one. Increasing the penalty parameter on transaction costs of selling and buying assets between trading days lowers the aggregated transaction cost and increases the performance of the optimal-weighted portfolio considerably. The best portfolio performance is obtained when at least 50% of the capital is invested equally among the assets when maximizing the modified Sharpe ratio. The optimal-weighted and equal-weighted portfolios are constructed on a daily basis, where the allowed VaR0:05 is €300 000 for each portfolio. This sets the limit on the amount of capital allowed to be invested each trading day, and is determined by empirical VaR0:05 simulations of these two portfolios.

Abstract:

Based on the assumption that returns in Commercial Real Estate are normally distributed, the Sharpe Ratio has been the standard risk-adjusted performance measure for the past several years. Research has questioned whether this assumption can be reasonably made. The Upside Potential Ratio as a risk-adjusted performance measure is an alternative to measure performance on a risk-adjusted basis but its values differ from the Sharpe Ratio's only in the assumption of skewed returns. We will provide reasonable evidence that CRE returns should not be fitted with a normal distribution and present the Gaussian Mixture Model as our choice of distribution to fit skewness. We will then use a GMM distribution to measure performance of CRE domestic markets via UPR. Additional insights will be presented by introducing an alternative risk-adjusted perfomance measure that we will call D-ratio. We will show how the UPR and the D-ratio can provide a tool-box that can be added to any existing investment strategy when identifying markets' past performance and timing of entrance. The intent of this thesis is not to provide a comprehensive framework for CRE investment decisions but to introduce statistical and mathematical tools that can serve any portfolio manager in augmenting any investment strategy already in place.

Abstract:

Our thesis was conducted through quantitative research on the validity of the Sharpe ratio as a performance measure in bear market conditions. Previous research had identified problems with mismatches in ranking due to Sharpe ratios rewarding unsystematic risk in funds. Alternative Sharpe ratios have been developed to solve this problem; Scholz (2006) developed the Normalized Sharpe ratio, which he argued to be a more valid performance measure in bear market conditions. We conducted a comparative analysis between rankings of the Sharpe ratio and Scholz Normalized Sharpe ratio to find out whether the Sharpe ratio provides mismatches in ranking due to rewarding unsystematic risk. The research was conducted on Swedish premium pension funds within the Swedish Pension system. We aimed to highlight the potential problems with interpreting the Sharpe ratio in bear market periods. Various models and theories was utilized to support our research question and attempt to link them to our quantitative analysis. The results from our analysis showed us that there were mismatches between the different ratios, additionally our findings provided support to previous researchers’ conclusions which stated that the Sharpe ratio rewards unsystematic risk.

Abstract:

This paper sets out to evaluate whether investment recommendations of South African share analysts provide any value to an investor in the Johannesburg Stock Exchange (JSE). The study focuses on the creation of a portfolio based on the recommendations by analysts between December 2002 and July 2010. The monthly returns and respective risk-adjusted returns of this portfolio are compared to those of the SATRIX Top 40 over the same period of time. The paper also evaluates the effectiveness of the SATRIX Top 40 as a performance benchmark by comparing it to a portfolio for shares of family-controlled or owner-managed companies listed on the JSE. The study utilises analyst consensus recommendations, with focus on buy and sell recommendations, to create a buy and hold portfolio that is compared to the SATRIX Top 40. The SATRIX Top 40 is further compared to ten-share portfolio of family-owned or owner-managed companies. The study finds that analysts’ recommendations lead to higher risk-adjusted returns for an investor when compared to the SATRIX Top 40. The returns are even better in a bear market environment when compared the benchmark SATRIX Top 40. It is also found that a portfolio of shares of family-controlled or owner-managed companies performs better than the SATRIX Top 40 and thus provides a better benchmark for an investor. Copyright

Abstract:

Bakgrund: De senaste åren har en stark underprissättningstrend observerats i det ökande antalet börsnoteringar, vilket har skapat ett starkt investerarintresse. En stor del av dessa nyintroducerade bolag är småbolag, varav de flesta noteras på mindre handelsplatsformer, så kallade MTF:er. MTF:en Aktietorget introducerade flest företag till den svenska aktiemarknaden 2010-2014, varför detta har valts till studiens undersökningsområde.Tidigare studier har bevisat att det finns en hög volatilitet i nyintroduktioner och småbolag, vilket i finansiella sammanhang betyder att en sådan investering är mer riskfylld. Dock saknas liknande studier på downside volatilitet, alltså risken för förlust. Denna studie ämnar därför att jämföra den traditionellt riskjusterade avkastningen i form av sharpekvoten, mot avkastningen justerad för downside risk, den så kallade sortinokvoten. Detta nyare mått på risk är en del av den postmoderna portföljteorin, som tar hänsyn till en mer förlustaversiv investerare. Syfte: Syftet med denna uppsats är att analysera den riskjusterade avkastningen i nynoteringar på Aktietorget för att jämföra med etablerade bolag på OMX Stockholm. Den riskjusterade avkastningen beräknas genom sharpe-respektive sortinokvoten och jämförs sedan för att undersöka eventuella skillnader i bedömningen av aktiernas prestation. Genomförande: Uppsatsen är en eventstudie med deduktiv ansats. Undersökningen har inkluderat nynoteringar på Aktietorget mellan 2010-2014 och jämförelseaktier består av branschindex från OMXSPI.Den riskjusterade avkastningen har beräknats via modifierade kvoter. Samband mellan sharpe-respektive sortinokvoten har undersökts genom icke-parametrisk rangordningskorrelation. Slutsats: Studien kan inte bevisa en signifikant abnormal avkastning i nynoteringar på Aktietorget, men observerar en genomsnittlig överavkastning upp till en månad. De riskjusterade kvoterna har mycket stark rangordningskorrelation, vilket innebär att studiens resultat inte kan motivera en fortsatt användning av sortinokvoten.
Background: In recent years, a strong underpricing trend has been observed in the increasing number of IPOs, which has created a strong investor interest. A large part of these IPO companies are small firms, most of which are listed on smaller trading venues, known as MTFs. The MTF Aktietorget introduced most companies to the Swedish stock market during 2010-2014, so it has been chosen as the area for this research.Previous studies have shown that there is high volatility in new introductions and small companies, which in financial terms means that such an investment contains more risk. However, similar studies on downside risk are lacking. This study therefore aims to compare the traditional risk-adjusted return in the form of the sharpe ratio, against the return adjusted for downside risk, the so-called sortino ratio. This newer measure of risk is part of the postmodern portfolio theory, which takes into account a more loss-aversive investor. Purpose: The purpose of this paper is to analyze the risk-adjusted return in IPOs on Aktietorget and compare it with the return of established companies on OMX Stockholm. The risk-adjusted return is calculated by the sharpe and sortino ratios, respectively, and are later compared with each other to investigate possible differences in the estimation of performance for the stocks. Methodology: This paper is an event study with a deductive approach. The study has included IPOs on Aktietorget between 2010-2014 and comparative stocks, consisted of industry index from OMXSPI.The risk-adjusted return has been calculated using modified ratios and the relationship between the sharp and sortino ratios has been investigated by non-parametric ranking correlations. Conclusion: The study can't prove any significant abnormal return in IPOs on Aktietorget, but observes an average excess return of up to one month. The risk-adjusted ratios have very strong rank correlation, thus empirical results can't motivate the continued use of the sortino ratio.

Abstract:

A dissertação aborda e compara as características dos índices de Sharpe (SR) e suas variantes, SRc e SRd, Sharpe generalizado (GSR ) e potencial de investimento (IP), sendo os índices GSR e IP associados a alguma função de utilidade. Pelo fato de o GSR e o IP serem idênticos, testes empíricos foram realizados entre SRc e o GSR. Ambos foram avaliados teoricamente sob dois aspectos, o que definimos de análise retrospectiva, i.e., análise de séries de log-retornos mensais observados, e a análise prospectiva, i.e., séries a ocorrer. No âmbito prospectivo, ex ante facto, o SRc (índice de Sharpe com variável de estado normal) e o SRd (índice de Sharpe com variável de estado lognormal), por estarem associados à função de utilidade quadrática, apresentam distorções como o ponto bliss e o agente econômico bomba de dinheiro. O mesmo ocorre no âmbito retrospectivo, ex post facto, com o GSR (potencial de desempenho de ativos de risco para indivíduos com função de utilidade HARA) quando o coeficiente de aversão ao risco é igual a um negativo, gama=-1. No entanto, o GSR pode ser associado a funções de utilidade diferentes da quadrática evitando seus efeitos indesejáveis. Sob a suposição de movimento browniano geométrico (MBG) e da utilidade HARA para o preço mensal ajustado de ações brasileiras e americanas e para pontos mensais de índices brasileiros e americanos, entre janeiro de 2000 e março de 2008, obtivemos os seguintes resultados: (1) o índice GSR para utilidade quadrática apresentou elevada correlação com o SRc; (2) a menor correlação de GSR com SRc ocorreu para utilidade logarítmica; (3) para a utilidade exponencial, o GSR apresenta elevado grau de correlação com o SRc. Os resultados mostraram que o GSR com utilidade exponencial é o índice que menos se aproxima do comportamento do GSR com utilidade quadrática. Sabendo-se das distorções da utilidade quadrática, a adoção do GSR com gama=1 parece mais adequado para a classificação de ativos de risco.
This master dissertation studies and compares the characteristics of Sharpe ratio and its variants, SRc and SRd, generalized Sharpe ratio (GSR) and investment potential (IP), both GSR and IP associated to any utility function. By the fact that GSR and IP are identical indexes, empiric tests were conducted between SRc and GSR. The indexes were evaluated theoretically under two different aspects: retrospective analysis, i.e., analyze the observed monthly log-returns, and prospective analysis, i.e., series to occur. Under prospective view, ex ante facto, SRc (Sharpe ratio with normal state variable) and SRd (Sharpe ratio with lognormal state variable), for being associated to the quadratic utility function, show the inherent problems to utility functions such as the bliss point and the pump money economic agent. The same happens in a retrospective view, ex post facto, with the GSR (performance potential with HARA utility function family) when the risk aversion coefficient equals minus one, gama=-1. Therefore, the GSR can be associated to different utility functions avoiding the undesirable effects. Under the GBM (geometric Brownian motion) condition and HARA utility function for the Brazilian and American adjusted monthly stock prices and indexes monthly points during January 2000 and March 2008, we reached the following: (1) results indicate that GSR for quadratic utility has high correlation level with SRc; (2) while the logarithmic utility showed lowest correlation level between GSR and SRc; (3) exponential utilities showed a high level of correlation between GSR and SRc. The results showed that GSR with exponential utility kept the biggest behavior difference for the GSR with quadratic utility. Based on the knowing problems of the quadratic utility, GSR with gama=1 seems to be a better index choice for risk assets classification.

Abstract:

The study evaluated the development role of targeted development investments in South Africa and their risk adjusted performance over a 10-Year period, that is from 2008 to 2017. Targeted development investments as a subset of socially responsible investments have transformed the way capital is allocated towards development funding needs. In the South African context this study is relevant given it offers a contrast between investments made in the public sector where development impact is a key objective, versus private sector targeted investments that aim to achieve financial returns whilst also driving development impact objectives aligned to sustainable development goals. The role and impact of these investments in the post democratic era is put in the spotlight given the country is dealing with economic, social, and environmental challenges that have necessitated the need to assess the nature and role of the investment industry in solving these complex development challenges (Giampocaro & Pretorius, 2012). The study on the role of the public sector focused on the investments and development impact indicators tracked by the Top 3 public sector investment institutions or corporations. The analysis on the performance of the private sector TDI funds examined their risk adjusted performance using Treynor, Sharpe, Sortino, and Information ratios. The risk adjusted performance was used to test whether the TDI fund returns under or outperformed against five benchmark categories. The research findings showed mixed results where TDI funds either underperformed or outperformed against the benchmark categories. The findings highlighted the need for a hybrid development model where both the public and private sector actively play a role in the development landscape as guided by their respective investment mandates. The findings advocate for corporate and institutional investors to increase capital allocations and investments towards financing development needs given the scope to maximise investor returns, whilst considering socially responsible investing and issues relating to the development and empowerment of previously disadvantaged communities.

Abstract:

Jämfört med andra branscher har fastighetsmarknaden låg avkastning på totala tillgångar, de utnyttjar istället en hävstångsstrategi för att skapa mer effektiv utväxling på eget kapital. Det finns många riskvariabler kopplat till fastighetsbranschen och flera sätt att differentiera sig från den osystematiska risken. De kommunala fastighetsbolagen har en finansieringskälla Kommuninvest, som enbart vänder sig till allmännyttiga bolag och inte privata aktörer. Syftet med uppsatsen är att historiskt analysera hur risk och avkastning genererats av kommunala och privata fastighetsbolag. Metoden är kvantitativ, kombinerat med en deduktiv metod och som har en förklarande ansats. Utifrån teori har vi formulerat tre hypoteser för att undersöka om vi kan finna indikatorer på hur kommunala och privata fastighetsbolag skiljer sig till från varandra. För att genomföra undersökningen har uppsatsen utgått från en kvantitativ metod och statistiska test har gjorts för att kunna analysera utfallen. Resultaten indikerar på att det finns en signifikant skillnad mellan kommunala och privata fastighetsbolag i två av hypoteserna. Hur undersökningen är genomförd beskrivs i den empiriska metoden. Från de resultat som blivit har det fastställts att det finns mer att undersöka och nya förslag på fortsatt forskning har utformats.
Compared to other industries, real estate markets have historically low return on total assets, instead they use a leverage strategy to create a more efficient ratio on return on equity. There are many risk variables associated with real estate and several ways for real estate firms to differentiate themselves from the unsystematic risk. The municipal property firms have a funding source Kommuninvest, only turning to public utilities and not private actors. The purpose of this paper is to analyze the historical risk and return generated by municipal and private property firms. The method is quantitative, combined with a deductive theory, which has an explanatory approach. Based on theory we have formulated three hypotheses to explore and see if we can find indicators of how differences between municipal and private property is. To conduct the survey, the thesis has a quantitative method and statistical tests to analyze the outcomes. The results indicate that there is a significant difference in two of the hypotheses between municipal and private property. How the survey is conducted is described in the empirical method. From the results determined, the intention shows that there is more to explore, and new suggestions for further research have been suggested.

Abstract:

In this paper, I evaluate the out-of-sample performance of the portfolio optimizer relative to the naïve and market strategy on the Swedish stock market from January 1998 to December 2012. Recent studies suggest that simpler strategies, such as the naïve strategy, outperforms optimized strategies and that they should be implemented in the absence of better estimation models. Of the 12 strategies I evaluate, 11 of them significantly outperform both benchmark strategies in terms of Sharpe ratio. I find that the no-short-sales constrained minimum-variance strategy is preferred over the mean-variance strategy, and that the historical sample estimator creates better minimum-variance portfolios than the single-factor model and the three-factor model. My results suggest that there are considerable gains to optimization in terms of risk reduction and return in the context of portfolio selection.

Abstract:

Bakgrund: Under flera årtionden har handeln med aktier och värdepapper moderniserats och utvecklats. En investerare kan idag placera en order för att köpa en aktie över hela världen. Investerare letar alltid efter nya aktier att investera för att maximera sin avkastning dock medför detta en risk. Att analysera en investering kan göras på flera olika sätt där Sharpekvoten är en av flera sätt att analysera på. Tidigare har Sharpekvoten oftast använts vid analys av fonder och inte aktier och i tidigare forskning används Sharpkvoten flitigt men flera olika parametrar används då. Syfte: Studiens syfte är att undersöka skillnaderna i portföljer med aktier med låg risk kontra portföljer med aktier med hög risk och se vilken av dessa typer av portföljer som gett bäst avkastning, i förhållande till den risk som tagits. Sharpekvoten kommer att användas som ett nyckeltal för att svara på syftet. Metod: Studien har behandlat aktier på den Svenska, Amerikanska och Japanska marknaden och på dess Large- och Small cap marknader. Utifrån den data som har samlats in har en kvantitativ studie utförts för att sedan analyserats i förhållande med de teorier och studier som har berörts. Studien har även kompletterats med intervjuer för att bredda analysen och tänkanden kring hur investerare agerar vid hög risk aktier. Resultat: Sharpekvoten är högre på den svenska och japanska marknaden på respektive lands large cap samt 1st section. Intervjuerna som gjordes gav svaret att den bästa strategin är att differentiera sin aktieportfölj och att högrisk aktier endast bör utgöra en liten del av portföljen. I analysen framkommer det att sharpekvoten inte kan ge ett entydigt svar på förhållandet avkastning och risk, då det är vår uppfattning att avkastningen påverkas av en mängd andra faktorer.

This diploma thesis "A Performance Comparison of in Czech Republic available mutual funds and ETFs from the view of CZK investor" elaborates on collective investing in Czech Republic; focusing on mutual funds and their exchange traded alternatives in ETFs. In the thesis, a history of Czech collective investments' development is briefly mentioned and of ETFs' beginnings in the US, also a legislative framework for the mutual funds in CZ is shortly discussed; furthermore, different approaches to fund classification based on various criteria are provided. An impact of fund fees and expenses is also analysed. A Current situation on the capital market of funds and ETFs and its trends are showed in many graphs and tables. In the second part of the thesis, author introduces not only the basic ones but also the more sophisticated methods of portfolio's or fund's performance measurements, including yields, risks, risk-adjusted yields etc... The third and last chapter aims at application of the previously mentioned methods on a selection of 20 funds and ETFs; therefore building a financial model enabling that. The analysis is viewed as from the CZK investor, thus all calculations are made in CZK.

Abstract:

Housing is both a durable good and an investment vehicle, which makes it importantin people’s daily life aswell as for a nation’s economy. This thesis innovatively applies the Sharpe ratio on evaluating the performance of the US residentialhousing market within the time period from 2005:Q1 to 2019:Q3, andinvestigates how this performance would react upon macroeconomic shocks,including sudden changes in GDP growth rate and personal income growthrate, by establishing a vector auto-regression model with the lag order of four.The main results are that: (1)in the long run, direct residential investments are not significantly more profitable than treasury bills but not disappointing compared to the market portfolio of Dow Jones Industrial Average; (2)the performance of residential investments seem to slightly and positively co-move withGDP and personal income growth rate; (3)the long-term impacts that sudden GDP and personal income growths have on the performance seem inconspicuous and tend to mitigate within about three years and (4) limited evidence supports the hypothesis that current housing market performance can help predictfuture GDP growth rate. Based on housing’s two purpose of consumption andinvestment and the empirical results showing that direct investments on residentialproperties have similar risk-adjusted return level to short-term treasurybills, I suggest that financially feasible households purchase their own houseinstead of renting for a long time, and that speculative investors avoid puttingmoney in residential properties unless they have access to inside information.
Bostäder kan betraktas både som en hållbar vara och som ett investeringsinstrument.De är essentiella för människors vardag och har en viktig roll förett lands ekonomi. Denna avhandling använder innovativt Sharpe-förhållandet för att utvärdera hur den amerikanska bostadsmarknaden presterade under perioden2005: kvartal 1 till 2019: kvartal 3. Den försöker även undersöka om denna prestation påverkas av makroekonomiska chocker inklusive plötsligaförändringar i BNP-tillväxttakt och personliga inkomsttillväxthastighet. Detta görs genom att upprätta en vektor autoregression modell med en fördröjningsordningför fyra. De viktigaste resultaten är att: (1) på långsikt är direktabostadsinvesteringar inte betydligt mer lönsamma än statsskuldväxlar dock är det hellre inte en besvikelse jämfört med en marknadsportföljen av Dow JonesIndustrial Average; (2) Prestationen av bostadsinvesteringar verkar vara svagt och samverkar positivit både med BNP och tillväxttakten för personinkomst.(3) De långsiktiga effekterna av plötsliga tillväxter av BNP och personliga inkomster har på utvecklingen verkar vara vaga och tenderar att mildra inomcirka tre år och (4) begränsade bevis stöder hypotesen om att nuvarande bostadsmarknadsresultat kan bidra till att förutsäga framtida BNP-tillväxttakten.Baserat på bostädernas två syften inom konsumtion och investeringar, visar deempiriska resultaten att direkta investeringar i bostadsfastigheter har en liknande riskjusterad avkastningsnivå som kortfristiga statsskuldväxla. Därför föreslår jag att ekonomisk stabila hushåll borde köpa ett eget hus istället för att hyraunder en lång tid, och att spekulativa investerare borde undvika att satsa pengar inom bostadsfastigheter såvida de inte har tillgång till insider-information.

Abstract:

The traditional way to analyze stocks and portfolios within the area of finance have been restricted to Sharpe and Markovitz. The Omega function and its properties enlighten the field of finance and differs from the traditional ways when it comes to the volatility of the stocks. The Omega function, the Sharpe performance criteria and mean-variance model by Markovitz will be used. All calculations are done in Matlab and the data sheets are excel tables. The aim of this thesis is to investigate the nordic small cap market by using the Omega function, Sharpe performance criteria and the mean variance model by Markovitz. In order to to see how the purposed methods differs.

Full text

Abstract:

In this thesis, portfolio optimisation is used to evaluate if a specific sample of portfolios have

a higher risk level or lower expected return, compared to what may be obtained through

optimisation. It also compares the return of optimised portfolios with the return of the original

portfolios. The risk analysis software Aegis Portfolio Manager developed by Barra is used for

the optimisations. With the expected return and risk level used in this thesis, all portfolios can

obtain a higher expected return and a lower risk. Over a six-month period, the optimised

portfolios do not consistently outperform the original portfolios and therefore it seems as

though the optimisation do not improve the return of the portfolios. This might be due to the

uncertainty of the expected returns used in this thesis.

Full text

Abstract:

This study is a thesis ending a 120 credit masters program in Mathematics with specialization Financial Mathematics and Mathematical Statistics at the Royal Institute of Technology (KTH). The subject of Smart beta is defined and studied in an index fund context. The portfolio weighting schemes tested are: equally weighting, maximum Sharpe ratio, maximum diversification, and fundamental weighting using P/E-ratios. The outcome of the strategies is measured in performance (accumulated return), risk, and cost of trading, along with measures of the proportions of different assets in the portfolio. The thesis goes through the steps of collecting, ordering, and ”cleaning” the data used in the process. A brief explanation of historical simulation used in estimation of stochastic variables such as expected return and covariance matrices is included, as well as analysis on the data’s distribution. The process of optimization and how rules for being UCITS compliant forms optimization programs with constraints is described. The results indicate that all, but the most diversified, portfolios tested outperform the market cap weighted portfolio. In all cases, the trading volumes and the market impact is increased, in comparison with the cap weighted portfolio. The Sharpe ratio maximizer yields a high level of return, while keeping the risk low. The fundamentally weighted portfolio performs best, but with higher risk. A combination of the two finds the portfolio with highest return and lowest risk.
Denna studie är ett examensarbete som avslutar ett 120 poängs mastersprogram i Matematik med inriktning mot Finansiell Matematik och Matematisk Statistik på Kungliga Tekniska Högskolan (KTH). Ämnet Smart beta studeras i kontexten av en indexfond, där de olika testade principerna för viktning i portföljerna är: likaviktad, maximerad Sharpe-kvot, maximerad diversifiering, och fundamental viktning användandes av P/E-tal. Utfallet i testerna utvärderas i ackumulerad avkastning, portföljrisk, kostnad att handla i portföljen, och ett antal mått på fördelningen av tillgångarna. Studien går stegvis igenom processen för att samla in, ordna, och ”tvätta” data. En kort förklaring av historisk simulering, metoden för att estimera stokastiska variabler såsom kovariansmatriser, är inkluderad, såväl som en analys av distributionen av data. Processen för att optimera portföljerna och hur regler för att vara en UCITS-fond kan omformas till optimeringsvillkor beskrivs. Resultaten indikerar att alla utom den mest diversifierade portföljen har högre ackumulerad avkastning än den marknadsviktade portföljen under testperioden. I alla testade fall ökar handelsvolymen liksom marknadspåverkan när en annan strategi än marknadsviktad används. Portföljen med maximerad Sharpe-kvot ger en hög avkastning med bibehållen låg risk. Den fundamentalt viktade portföljen ger bäst avkastning, men med en litet förhöjd risk. Kombinationen av de båda metoderna ger den portföljen med högst ackumulerad avkastning och samtidigt lägst risk under testperioden.

Abstract:

Over the past years, the total assets under management among hedge funds and equity mutual fundshave increased significantly. The question from an investor point of view iswhich investment vehicle can provide the greatest return adjusted for risk. The purpose of this study involves an analysis on the historical net asset values todetermine and evaluate what one can except from actively managed hedge andequity mutual funds. It supports the determination of the most profitable asset, adjusted for risk, as part of a diversified portfolio. The performance is measured net of fees and costs with the inclusion of potential performance fees individual hedge funds may apply. Hedge funds practice different investment approaches depending on what strategy is applied and hence, return levels can vary dramatically. The study is designed to answer questions by comparing net returns and risk-adjusted returns for respective investments and the different hedge fund strategies. With a deductive research approach, the analysis is conducted by applying existing models and theories as the Fama-French three-factor model through time-series regressions measuring excess returns (alpha), risk-adjusted performance measures as Sharpe ratio, M-squared and the Sortino ratio. The results show that hedge funds outperform equity mutual funds in all examined aspects and produce positive monthly net alphas,on average. Equity mutual funds are unable to provide investors with positive excess returns and subsequently fail the purpose of an actively managed fund by providing returns lower than the return of the market. The results are increasingly strengthened with both time-series regressions and performance measures showing homogenous results and reaching the equal conclusions. From the conclusions that hedge funds provide the most profitable investment compared to equity mutual funds, the hedge fund strategy CTA/managed futures strategies perform best in both net and risk-adjusted terms.

Abstract:

There are different types of risk, examples include credit risk, liquidity risk and financial risk. In DeMarzo & Berk (2011, s. 293) is a study presented which is based on the yield of different types of financial assets between 1925 and 2009, the study show that a high risk gave substantially higher reward. With the study as a background, it is interesting to study practical risk management within participants of the financial markets of Sweden. In risk management there are several theories about whether risk can be calculated and analyzed with scientific methods in practice. To generate new empirical data a qualitative method was used in the form of interviews. The selection, which was strategic, was based on mailed questionnaire sent to participants of the Swedish fund market. Theory can be problematic to apply in practice, since reality is often simplified in theory, as discussed by Franklin (2004). Franklin’s thoughts are accompanied by Baird (2010) in a similar discussion. The main model of the study is Value at Risk, which is recovered from Hull (2011) but has its origin from the financial company JP Morgan. Other models that are applied in the study are Capital Asset Pricing Model, CAPM, and the Sharpe ratio. There are known critiques against these models, which are discussed in this study. In the study it is shown that all the participants applied the model Value at Risk. The report also indicates that standard deviation has a central role in risk management. All the respondents were well aware of the critique against Value at Risk. To manage the flaws of the model they also used stress tests as a complement. The analysis of the study indicates that practical and theoretical application in many aspects are similar, the most apparent one being Value at Risk. Even though there are some differences, CAPM was indicated to have no practical use for any of the participants. Two vital factors for whether a model can be applied practically are the model’s simplicity and the need for assumptions to correlate with reality. Having completed this study, the conclusion that the participants successfully applied theoretical risk management models in practice can be validated.

Full text

Abstract:

Sharpekvoten är ett av de mest frekvent använda prestationsmåtten för fonder. Kvoten beskriver en fonds riskjusterade avkastning genom att dividera dess överavkastning med dess standardavvikelse. Måttet har emellertid fått kritik på flera områden och visat sig vara missvisande under vissa scenarion, något som även denna studie påvisar. Studien bygger på en kvantitativ metod där ett stickprov används för att beskriva den studerade populationen; Sverigefonder. Studiens resultat visar att Sverigefonders avkastning inte är normaldistribuerad, något som är ett grundantagande vid Sharpekvots-beräkningen då fondens standardavvikelse används. Resultaten visar att samtliga observationers avkastningsdistribution antingen är positiv eller negativs skev, vilket leder till att standardavvikelsen konsekvent över- eller underskattar tillgångens risk. Tidigare studier betonar att även avkastningsdistributionens skevhet har betydelse vid investeringar. Denna aspekt återspeglas dock inte i den traditionella Sharpekvoten och författaren presenterar därför en egen modifikation av måttet där avkastningsdistributionens skevhet adderas. Studiens resultat bör tolkas ur ett behavior-finance-perspektiv, där människor antas ha olika tidshorisont för investeringar, inte antas agera rationellt, samt påverkas känslomässigt av marknadshändelser. Med det som utgångspunkt adderar avkastningsdistributionens skevhet värdefull information för investeraren, bortom fondens medelavkastning och standardavvikelse som enligt modern portföljteori är de enda två aspekterna en investerare har preferenser om. En ytterligare aspekt som påvisas i studien är att det tycks finnas en osund informationsassymetri mellan spararna och fondkommissionerna, samt strukturella incitament för att behålla denna. Detta kan ses som en förklaringsgrund till det minskade förtroendet som växt fram för de aktivt förvaltade fonderna. Författaren föreslår ökad transparens från fondkommissionernas sida och ser en presentation av en skevhetsjusterad Sharpekvot som ett steg på vägen. Studien bidrar till tidigare forskning genom att empiriskt påvisa fördelen med en modifikation av Sharpekvoten som adderar informationsvärde för investerarna.
The Sharpe ratio is one of the most frequently used performance measures for funds. The ratio is describing a fund’s risk adjusted return by dividing its excess return by its standard deviation. The measure has been subject to critique in several areas and has shown to be misleading under certain scenarios, something that this study also indicates. The study is conducted based on a quantitative method where a sample is used to describe the target population; Sverigefonder. The results of the study shows that Sverigefonders return is not normally distributed, something that is elementary assumed when calculating the Sharpe ratio by the usage of the standard deviation. The results show that all the observations’ return distribution either is positively or negatively skewed. The implication of that is that the standard deviation consistently either over- or under estimates the asset’s risk. Previous studies emphasize that the skewness of the return distribution is of importance as well when investing. This aspect is not reflected though in the traditional Sharpe ratio and the author is therefor presenting an own modification of the performance measure where the skewness is added to the ratio. The results of the study should be interpreted from a behavior finance perspective, where investors are assumed to have different time horizons for investing, act irrational, and reacting emotionally to market events. With those aspects as the premise, the skewness of the return distribution is adding valuable information for the investor, beyond the fund’s average return and standard deviation, which are the only two aspects that the investor has a preference regarding according to modern portfolio theory. One additional aspect that is shown in the study is that there seems to exist an unhealthy information asymmetry between the investors and the fund commissions, and structural incentives to keep it. This can be seen as a suggestion of explanation to the lowered trust for the actively managed funds. The author is proposing enhanced transparency for the fund commissions and sees the presenting of a skewness-adjusted Sharpe ratio as a step in that direction. This study is contributing to previous research by empirically showing the advantage off presenting a modification of the Sharpe ratio, which adds additional information to the investors.

Abstract:

During the past few decades, social responsible investing (SRI) has rapidly grown to become a renowned investment strategy. Because of the contradictory findings on how successful this strategy is in terms of financial return, the aim of this thesis is to compare the performance of sustainable and conventional funds in four different geographical areas during the last three years. With the use of regression analysis, the correlation between the Portfolio Sustainability Score of a fund, which is a Morningstar-provided rating that represents how well a fund incorporates ESG, and its risk-adjusted return is determined. The final results of this analysis varies among the four geographical regions. The correlation between the two variables is positive in USA and Asia ex-Japan, whereas a negative relationship is found in Europe and the Nordic region. However, the obtained findings are not of statistical significance, implying that there is no difference between the risk-adjusted returns of sustainable versus conventional funds.
Under de senaste årtionden har hållbara investeringar ökat och på senare tid även blivit en väletablerad investeringsstrategi. Då tidigare studier inom området uppvisat motstridiga resultat gällande hur effektiv denna strategi är inom värdeskapande, fokuserar denna rapport på att klargöra ifall hållbara alternativt vanliga fonder är fördelaktiga utifrån ett finansiellt perspektiv. Mer specifikt undersöks fyra geografiska områden över en tidsperiod på tre år. Genom regressionsanalys bestäms korrelationen mellan en fonds Portfolio Sustainability Score, ett betyg som erhålls av Morningstar som representerar hur väl den specifika fonden inkorporerar ESG, och dess riskjusterade avkastning. De slutgiltiga resultaten av denna analys varierar i de fyra geografiska områdena. I USA och Asien där Japan exkluderas är korrelationen positiv medan en negativ korrelation råder i Europa och Norden. Dock är resultaten inte av statistisk signifikans vilket indikerar att det inte är någon skillnad i den riskjusterade avkastningen mellan hållbara och vanliga fonder.

Abstract:

The concept of emerging markets came to surface in early 1980 and constituted of only eight countries from the two continents of South America and Asia. The globalization of financial markets has since raised the importance of emerging capital markets. We take a quantitative approach to investigate the performance of emerging markets compared to developed markets. The aim of the study is to conclude if emerging markets offers investment value and if logic in portfolio theory can be used to improve the chance of creating a relatively better performing investment. Included markets in our study are Brazil, Russia, India, China, Colombia, Indonesia, Vietnam, Egypt, Turkey and South Africa. S&P 500 is our benchmark for developed market performance. Sample period is 2002-01-01 to 2011-12-31 and monthly return data, creating 120 data points on each index. The weighting schemes used for the portfolios are min variance optimization, geographical location and high and low correlation. All investments are scored on performances in correlation to S&P 500, inflation adjusted growth, currency effect, Sharpe ratio, skewness and kurtosis. Rankings are done on the separate categories, on the individual overall ranking on only countries and one overall ranking on all investments. A brief overview of the overall ranking for all investments suggest that medium performing investments are overrepresented (12/20) and the low and high is underrepresented (3/20 and 5/20). Of note is that the min variance portfolio outperforms its components, the geographical portfolios have a wide range and the high correlated portfolio outperforms the low. The country to portfolio ratio over each grade suggests only a small skew of the results. There is no low scoring portfolio but the other two ratios are close to 50/50, suggesting that on average the portfolios create diversification benefits. Furthermore normality of returns seem to be violated and then the concept of volatility as a risk measure is significantly impaired also currency risk can be of high importance, currency effects ranged from -48% to 28.7%. Assuming non-normality seems more accurate than assuming normality; therefore we need to improve on volatility as a tool to measure risk. So one direction for further research we see a need is in the concept of volatility. The initial reason for this research came from small investors’ seemingly intuitive knowledge that emerging markets are a suitable investment option. We have concluded that they in fact are, therefore we suggest that a qualitative study is conducted to investigate this seemingly natural intuition.

This paper is an empirical study on Harry Markowitz work on Modern Portfolio Theory. The model introduced by him assumes the normality of assets’ return. We examined the OMX Large Cap List1 by mathematical and statistical methods for normality of assets’ returns. We studied the effect of the parameters, Skewness and Kurtosis for different time series data. We tried to figure it out which data series is better to construct a portfolio and how these extra parameters can make us better informed in our investments.

Abstract:

Hedge funds are a debated subject in today’s financial industry. During 2008, despite hedge funds absolute return target, the global hedge fund industry showed a negative performance whilst the Swedish hedge fund market performed relatively well in comparison. Many studies have been made investigating the effect on incorporating hedge funds in a traditional portfolio though none focused separately on the Swedish market. In a global perspective it is quite easy to invest in hedge fund portfolios due to the existence of investable indices. To invest on the Swedish market is a more complex matter. SIX Harcourt HFXS Index is a Swedish hedge fund index representing the Swedish hedge fund market though it is not investable. Hence it would be interesting to see if it is possible to create an investable version of SIX Harcourt HFXS. When creating an investable index, several administrative costs will arise and in order to cover these costs it would be interesting to see whether or not it possible to optimize SIX Harcourt HFXS Index in purpose of achieving a outperformance which could cover any administrative costs for setting up the investable version. Also, since the optimized version must replicate the standard SIX Harcourt HFXS Index it must maintain a certain level of correlation.

This thesis, which is based on a positivistic epistemology, is built upon a quantitative case study where SIX Harcourt HFXS Index is optimized in purpose of achieving an outperformance in terms of the risk-adjusted return. The optimization uses an adjusted mean-variance methodology and is limited to a maintained correlation above 0,9 towards the standard SIX Harcourt HFXS Index. The optimization is created through the use of an Excel application created by Harcourt Investment Consulting.

Also, based on the outperformance by Swedish hedge funds compared to global hedge funds, this study aims to show the effect of incorporating Swedish hedge funds in a traditional portfolio consisting of equities and bonds. This effect is analyzed by the use of several performance-and risk measures.

The study shows that it is possible to optimize SIX Harcourt HFXS Index and produce an outperformance of approximately 1,5% per annum with a maintained correlation above 0,9. It also shows that the effect of incorporating Swedish hedge funds to a traditional portfolio is positive in regards to both risk and return.

Abstract:

L’objectif principal de cette thèse est d’apporter de nouveaux résultats théoriques concernant la performance d’investissements basés sur des modèles stochastiques. Pour ce faire, nous considérons la stratégie optimale d’investissement dans le cadre d’un modèle d’actif risqué à volatilité constante et dont la tendance est un processus caché d’Ornstein Uhlenbeck. Dans le premier chapitre,nous présentons le contexte et les objectifs de cette étude. Nous présentons, également, les diﬀérentes méthodes utilisées, ainsi que les principaux résultats obtenus. Dans le second chapitre, nous nous intéressons à la faisabilité de la calibration de la tendance. Nous répondons à cette question avec des résultats analytiques et des simulations numériques. Nous clôturons ce chapitre en quantiﬁant également l’impact d’une erreur de calibration sur l’estimation de la tendance et nous exploitons les résultats pour détecter son signe. Dans le troisième chapitre, nous supposons que l’agent est capable de bien calibrer la tendance et nous étudions l’impact qu’a la non-observabilité de la tendance sur la performance de la stratégie optimale. Pour cela, nous considérons le cas d’une utilité logarithmique et d’une tendance observée ou non. Dans chacun des deux cas, nous explicitons la limite asymptotique de l’espérance et la variance du rendement logarithmique en fonction du ratio signal-sur-bruit et de la vitesse de retour à la moyenne de la tendance. Nous concluons cette étude en montrant que le ratio de Sharpe asymptotique de la stratégie optimale avec observations partielles ne peut dépasser 2/(3^1.5)∗100% du ratio de Sharpe asymptotique de la stratégie optimale avec informations complètes. Le quatrième chapitre étudie la robustesse de la stratégie optimale avec une erreur de calibration et compare sa performance à une stratégie d’analyse technique. Pour y parvenir, nous caractérisons, de façon analytique,l’espérance asymptotique du rendement logarithmique de chacune de ces deux stratégies. Nous montrons, grâce à nos résultats théoriques et à des simulations numériques, qu’une stratégie d’analyse technique est plus robuste que la stratégie optimale mal calibrée
The aim of this thesis is to study the robustness of the optimal trading strategy. The setting we consider is that of a stochastic asset price model where the trend follows an unobservable Ornstein-Uhlenbeck process. In the ﬁrst chapter, the background and the objectives of this study are presented along with the diﬀerent methods used and the main results obtained. The question addressed in the second chapter is the estimation of the trend of a ﬁnancial asset, and the impact of misspeciﬁcation. Motivated by the use of Kalman ﬁltering as a forecasting tool, we study the problem of parameters estimation, and measure the eﬀect of parameters misspeciﬁcation. Numerical examples illustrate the diﬃculty of trend forecasting in ﬁnancial time series. The question addressed in the third chapter is the performance of the optimal strategy,and the impact of partial information. We focus on the optimal strategy with a logarithmic utility function under full or partial information. For both cases, we provide the asymptotic expectation and variance of the logarithmic return as functions of the signal-to-noise ratio and of the trend mean reversion speed. Finally, we compare the asymptotic Sharpe ratios of these strategies in order to quantify the loss of performance due to partial information. The aim of the fourth chapter is to compare the performances of the optimal strategy under parameters mis-speciﬁcation and of a technical analysis trading strategy. For both strategies, we provide the asymptotic expectation of the logarithmic return as functions of the model parameters. Finally, numerical examples ﬁnd that an investment strategy using the cross moving averages rule is more robust than the optimal strategy under parameters misspeciﬁcation

Abstract:

This paper analyses the difference in risk-adjusted returns between Sin-stocks and SRI-investing for the period 2001-2021. The analysis was conducted by creating two optimally risky portfolios according to the Modern Portfolio Theory, one comprised of only Sin-stocks and one with only high ESG scoring companies. The Sin-stocks contained stocks from four different sectors, alcohol, gambling, tobacco and weapons while the companies for the SRI-portfolio was chosen from the FTSE4Good index. The regression models were chosen to follow both the CAPM, and the Fama & French three factor model and the regressions were in the end conducted with the GARCH model which showed results that both the SRI-portfolio and the Sin-portfolio had a general excess return over the market. The two portfolios were also compared with the help of Sharpe Ratio and Jensen’s Alpha. The Sharpe ratio as well as the Jensen’s Alpha showed that the Sin-portfolio had the highest risk-adjusted returns. In conclusion, the SRI-portfolio as well as the Sin-portfolio both outperformed the market during the time period 2001-2021 and they were both less volatile than the market.

Mutual funds performance evaluation is, traditionally, made using Sharpe Ratio that considers only the first and the second moments of the return distribution (mean and variance), but it requires assumptions on the normality of the returns distribution and on the investor’s utility function as quadratic. However, it is well known that a quadratic utility function is inconsistent with investor behavior and some funds, like hedge funds, have returns distributions far from a normal distribution Keating and Shadwick (2002a, 2002b) proposed a new measure called Omega that incorporates all the moments of the distribution, and has the advantage of requiring no assumptions on the returns distribution or on the utility function of a risk averse investor. The purpose of this work is to verify if this measure has a greater forecast power than other performance measures, like Sharpe and Sortino Ratios. The empiric study indicated that Omega measure makes a ranking, most of the time, different from the other measures. Despite the portfolios constructed with Omega have had an average return greater than the average return of the portfolios constructed using the other measures, in almost all the tests, this difference of averages of returns was significant only in some cases. In spite of this, there is a light indication that Omega measure is the most appropriate for the use of investors when is made the performance evaluation of mutual funds.
A avaliação de desempenho de fundos de investimentos é, tradicionalmente, realizada utilizando-se o Índice de Sharpe, que leva em consideração apenas os dois primeiros momentos da distribuição de retornos (média e variância), assumindo as premissas de normalidade da distribuição de retornos e função quadrática de utilidade do investidor. Entretanto, é sabido que uma função de utilidade quadrática é inconsistente com o comportamento do investidor e que as distribuições de retornos de determinados fundos, como os hedge funds, estão longe de serem uma distribuição normal. Keating e Shadwick (2002a, 2002b) introduziram uma nova medida denominada Ômega que incorpora todos os momentos da distribuição, e tem a vantagem de não ser necessário fazer premissas sobre a distribuição dos retornos nem da função de utilidade de um investidor avesso ao risco. O objetivo deste trabalho é verificar se esta medida Ômega tem um poder de previsibilidade maior que outras medidas de avaliação de desempenho, como o Índice de Sharpe e o Índice de Sortino. O estudo empírico indicou que a medida Ômega gera um ranqueamento, na maioria das vezes, relativamente diferente das outras medidas testadas. Apesar das carteiras formadas com base na medida Ômega terem gerado um retorno médio maior que o retorno médio das carteiras formadas pelas outras medidas em praticamente todos os testes, esta diferença entre as médias dos retornos só foi significativa em alguns casos. Mesmo assim, há uma leve indicação de que a medida Ômega é a mais apropriada para utilização do investidor ao fazer a avaliação de desempenho dos fundos de investimentos.

This explorative study is about the influencing effects of US macroeconomic announcements on changes in systematic risk with the focus on the difference between emerging and developed markets. Seven different US macroeconomic indicators have been examined and used to estimate betas as a proxy for the systematic risk around the announcement dates. In the period from 1996 until 2017, betas have been estimated over a three-month pre- and post window, resulting in 27 announcements per US macroeconomic indicator. The study also tries to provide insights of the consequences for portfolio managers, based on patterns of changes in betas and their relationship with changes in Sharpe ratios. The study results reveal that betas change consistently over the sample period, however, to a small magnitude. Also, the changes in mean Sharpe ratios around these announcement dates have not been found as statistical significant. However, the study results indicate that there is a positive relationship between changes in Sharpe ratios and changes in betas for developed countries as the Pearson correlation coefficient illustrates.
O seguinte estudo analisa a influência das publicações de dados macroeconómicos nas variações do risco sistemático, salientando os diferentes efeitos sobre os mercados emergentes e os países desenvolvidos. Foram examinados sete diferentes indicadores macroeconómicos dos EUA, sendo estes utilizados para determinar uma estimativa dos valores do risco sistémico perto das datas das publicações macroeconómicos dos EUA. No período entre 1996 e 2017, os betas foram estimados sobre um intervalo de tempo de três meses antes e depois de cada publicação, resultando em 27 publicações por cada indicador do EUA. Nesta análise também se tenta explicar as consequências destes efeitos para os gestores de carteiras, baseando-se em padrões de variações dos betas e a sua relação com as variações dos Sharpe Ratios. Os resultados desta análise evidenciam que os betas variam consistentemente ao longo do período da amostra, ainda que numa baixa magnitude. Além disso, as variações no valor médio dos Sharpe Ratios nas datas próximas aos relativos anúncios económicos não são estatisticamente significativas. Contudo, os resultados desta análise indicam que existe uma relação positiva entre variações dos Sharpe Ratios e variações nos betas dos países desenvolvidos, como o coeficiente de correlação de Pearson demonstra.

Abstract:

We consider a mechanistic non-linear machine learning approach to learning signals in financial time series data. A modularised and decoupled algorithm framework is established and is proven on daily sampled closing time-series data for JSE equity markets. The input patterns are based on input data vectors of data windows preprocessed into a sequence of daily, weekly and monthly or quarterly sampled feature measurement changes (log feature fluctuations). The data processing is split into a batch processed step where features are learnt using a Stacked AutoEncoder (SAE) via unsupervised learning, and then both batch and online supervised learning are carried out on Feedforward Neural Networks (FNNs) using these features. The FNN output is a point prediction of measured time-series feature fluctuations (log differenced data) in the future (ex-post). Weight initializations for these networks are implemented with restricted Boltzmann machine pretraining, and variance based initializations. The validity of the FNN backtest results are shown under a rigorous assessment of backtest overfitting using both Combinatorially Symmetrical Cross Validation and Probabilistic and Deflated Sharpe Ratios. Results are further used to develop a view on the phenomenology of financial markets and the value of complex historical data under unstable dynamics.

Abstract:

Purpose: The main purpose of this study is to study the 45 funds, divided into three differentdivisions, then the result will provide a greater understanding of how returns change with ahigher risk.

Methodology: The study is based on a quantitative approach. The survey was conducted bygathering raw data from databases and secondary data from literature, printed and electronicsources.

Theoretical perspectives: The study is based on the theory: the efficient markethypothesis, which argues that future returns can not be calculated as the market is fullyinformed. The study is therefore studying historical yields.

Empirical foundation: Empirical data are acquired from www.morningstar.se, andtherefore also treated on this page. The material is then divided into documents and time axes.

Conclusions: The study has shown that high-risk funds give a higher percentage returns thanmedium-and low-risk funds. However, does not imply a higher risk automatically earn ahigher return when the low-risk funds have shown a higher yield than medium-risk funds. Animportant factor to study when you are looking for the fund which generated the highest ROIis the Sharpe ratio. Although this study demonstrates that high-risk funds have a higherSharpe ratio than competing risk groups.

Abstract:

This thesis investigates and compares the performance and characteristics of defensive and cyclical sectors on the Swedish stock market during 2003-2020 and the financial crisis in2007-2008, taking monthly price developments from nine sectors. The purpose is to examine the differences in sector performances based on the estimations of systematic risk. Using the relationship between risk and return, we aim to find the most beneficial investment strategy for investors with a long-term investment horizon and provide knowledge to investors who may want to change investment schemes during stock market crises to protect their portfolios from risk. To determine the sectors' classifications, the beta coefficient from CAPM is used. Moreover, alpha and Sharpe ratios are used as performance measures with the aim to find evidence of differences in performance between the classifications. The results show that beta is inconstant over time, and sectors behave differently depending on their dependence to business conditions, demonstrated by different patterns in beta for the two different classifications when comparing the crisis to the full period. The empirical evidence indicates that a defensive investment strategy is beneficial when considering the relationship between risk and return.

Abstract:

The cryptocurrency market is continuously growing but is still a relatively unexplored field within academic research. The ambition with this thesis is to increase existing research on market efficiency of cryptocurrencies, by studying the risk exposure of identical investments between different cryptocurrency exchanges. The study includes four cryptocurrencies and nine different exchanges, the data is tested on a full sample period and two subsample periods. The results reveal significant Sharpe ratio differences for identical investments on selected exchanges, but also improved efficiency between the first and second subsample periods. The study concludes that there are significant market inefficiencies on the cryptocurrency market, but the results also suggests that the market is becoming more efficient over time.

Abstract:

This study examines how investors can take advantage of Black Swan events by applying an investment strategy that involves investing in stocks that have performed badly during Black Swan events. The stocks are chosen from and compared to the Dow Jones Industrial Average Index. The purpose is to find out if the investment strategy has had a higher return than the benchmark index DJIA. The results show that the investment strategy outperforms the DJIA by 111% between the years 2000 to 2020, however, the results show no statistical significance. Beta is used as risk measurement to explain the correlation between the portfolios and the benchmark index by calculating CAPM. Standard deviation is used to calculate the Sharpe ratio and thereby assess a risk-adjusted result.

Abstract:

Problem: Do ethical investments perform better than conventional investments? Purpose: To evaluate whether Shariah-compliant indexes and/or socially responsible indexes can improve financial performance of an investment portfolio. Sub-problem: What kind of relationship exists between socially responsible investments and faith-based investments, represented by Shariah-compliant investments? Sub-purpose: To discover how two types of ethical investments, socially-responsible and Shariah-compliant, are related. Method: Quantitative study, covering three types of investment styles of four index families during the period from 2000 until 2011. Financial performance evaluation through the Sharpe ratio, Treynor ratio and Jensen’s alpha. Conclusions: Conventional, socially responsible, and Shariah-compliant indexes do not have any significant differences in financial performance on a global basis. However, Shariah-compliant indexes could slightly over-perform conventional and socially responsible indexes during financial downturns. In the same time socially responsible indexes were noticed to be the most volatile during the whole period of study, to compare with conventional and Shariah-compliant. Regarding relationships, high correlations were found between ethical indexes, as well as between ethical and conventional indexes.

Abstract:

This paper discusses the indicators of financial success for Swedish companies from 1995 until 2005. Quarterly data on 42 Swedish companies were collected from the Datastream data base and analysed by using both portfolio analyses and parametric analysis. In this study, financial success is measured by using the acclaimed concepts of the Sharpe ratio and the Jensen’s Alpha. The Sharpe ratios of the companies are studied between 1995-2005 and this discussion is complemented by analysis of the Jensen’s Alpha in the second half of that time period i.e. 2000-2005. The relationship between these performance metrics and certain company-characteristics such as the book-to-market ratio, the ROA measure and capital structure is studied. The conclusion is that companies that have a high degree of profitability and maintain high book-to-market ratios outperform other companies in terms of generating excess returns to shareholders. Another interesting observation is the fact that company size does not have any significant relationship to company performance.

Abstract:

In this thesis, we conduct a case study by applying simple technical trading rules on Chinese stock market. The technical trading rules we tested are moving average rules and trading range breakout rules. The stock indices we tested are SSE A (Shanghai A) and SZSE (Shenzhen A) share, these shares are limited to the Chinese domestic traders. Our main trading rule frameworks are mainly from Brock, Lakonishok& Lebaron (1992), which including the most basic technical trading rules and covered various length of period, however we add the 25 days moving average to our frame work. We obtained our data from DataStream; the data are the daily closing prices of two indices we mentioned above.

We compared the mean return and Sharpe ratio with buy and hold. We further calculated breakeven transaction costs to test whether the technical trading rules can still add wealth to investors after adjusting the transaction costs. Our results showed that most technical trading rules perform better than buy and hold. VMA perform better than FMA and TRB, short period (25 and 50 days) performed better than longer period. On mean return, our data violated the assumption of parametric statistical test. We performed non-parametric tests, all the trading rules showed statistical significance at 95% level than buy and hold except FMA (1, 25,0), all the trading rules resulted higher Sharpe ratio than buy and hold. On transaction costs, 7 trading rules on SSE A are performed poorer than buy and hold, all the other rules provided positive breakeven transaction costs. Across the entire trading rule, both stock markets offered positive break-even transaction costs, 0.436% for SSE A and 1.369% for SZSE A. and they are both higher than the maximum transaction costs one bears.

Abstract:

This paper investigates whether an Islamic screened benchmark index shows a different risk adjusted performance in comparison to a non-screened benchmark index. In contrast to other papers this study analyzes daily observations in the years from 2007 to 2012, a period heavily affected by the financial crisis. The Capital Asset Pricing Model and the Jensen measure of abnormal returns are used to estimate and compare the indexes mean risk-adjusted returns. The results show that the Islamic index does not reveal any different level of daily mean risk-adjusted returns compared to the conventional non-screened index. Hence, Muslims who align their investments according to the teachings of Islam are not worse off than non-restricted investors following the screened Islamic index.

Abstract:

The study examines how the investment strategy Magic Formula (Greenblatt, 2006) has performed on the Swedish stock market. It is also investigated how the performance is affected when the strategy is combined with momentum. Since the expected pension for future generations is expected to decline it is important to have private savings with as high return as possible. Therefore, it is relevant to investigate if simple investment strategies can be used to achieve higher return. The purpose with this study is to find out if the investment strategies Magic Formula and Magic Formula combined with momentum has had a higher risk-adjusted return than the benchmark index OMX30. The results show that both Magic Formula and Magic Formula combined with momentum yielded a higher risk-adjusted return than the benchmark index. The results also showed that Magic Formula yielded an even better risk-adjusted return when it was combined with momentum. We wish that the result that was found in this study will give inspiration to private investors in order to achieve a higher return in their savings and a more satisfactory pension in the future

Abstract:

Active management funds are associated with higher transaction costs, which is something that has been acknowledged for a long time. The question is whether these costs can compensate with a higher return. This paper investigates how two active strategies, momentum and growth investing, have performed in relation to a passive index. To test this, we investigated the Frankfurt stock market during 2005-2020 on stocks from the automobile sector. By doing this, the purpose was investigated whether growth and momentum has had a higher risk-adjusted return than the benchmark index during the 15 years of observation. The result showed that both growth and momentum performed better than a passive index fund, despite its costly variables. However, the risk adjusted return was not significant higher. This study includes transaction costs in its calculation, which other studies ignore and focus on one industry with a consistent benchmark index for the same industry. By doing this, we believe that the test will be more accurate, and avoid potential industry effects on return and hopefully contribute with new thoughts on the subject.

In this paper, we present empirical evidence to investigate whether the propositions of the model of Frazzini and Pedersen (2014) apply to the Brazilian stock market. Using data from the year 2000 up to the first quarter of 2017, we find that the SML of this Market had a lower slope than that predicted by CAPM. In fact, it turned out to be negative, and this result was observed both in the time-series and in the cross-sectional analyzes. As a methodology to raise this evidence, 10 portfolios were created, organized in ascending order according to their respective betas. We calculated the returns relative to each portfolio and, with them, it was possible to verify that the portfolios with the highest beta performed less excess returns. In addition, we found that the Sharpe ratio was higher the lower the beta of the portfolios. Another proposition verified empirically in the Brazilian stock market, and in the considered period, was that the return of the BAB portfolios was positive. In addition, it was the largest one compared to others portfolios, and had the highest expected excess of return per unit of risk. Regarding the alpha, it was expected that the portfolios with higher beta had lower alpha. It was possible to verify this trend, but not in an undeniable way. This motivated us to make a small change in the model of Frazzini and Pedersen, which created a relation between the return of each one of the portfolios and the one of the BAB portfolio. The mathematical prediction, derived from the modified model, says that the coefficient of this relation is smaller the bigger the beta. It was possible to raise this empirical evidence in a clear way. This point was the great differential of this work, since we were the first to raise such evidence and to show that the BAB portfolios can be used as explanatory variable.
Neste trabalho, levantamos evidencias empíricas para investigar se as proposições do modelo de Frazzini e Pedersen (2014) se aplicam ao mercado acionário brasileiro. Utilizando dados que retomam o ano de 2000 até o primeiro trimestre de 2017, verificamos que a SML deste mercado é menos inclinada que a prevista pelo CAPM. De fato, ela chegou a ser negativa, sendo este resultado observado tanto nas analises em séries de tempo quanto nas em corte transversal. Como metodologia para levantar estas evidencias, foram criadas 10 carteiras, organizadas em ordem crescente segundo seus respectivos betas. Calculamos os retornos relativos a cada carteira e, com eles, foi possível verificar que os portfolios com maior beta realizaram menor retorno em excesso. Além disso, verificamos que o índice de Sharpe foi maior quanto menor foi o beta das carteiras. Outra proposição verificada empiricamente no mercado acionário brasileiro, e no período considerado, foi que o retorno das carteiras BAB foi positivo. Além disso, foi o maior entre todas as carteiras, ficando inclusive com o maior retorno esperado em excesso por unidade de risco. No que tange ao alfa, era esperado que as carteiras com maior beta tivessem menor alfa. Foi possível verificar esta tendência, mas não de maneira incontestável. Isso nos motivou a fazer uma pequena alteração no modelo de Frazzini e Pedersen, a qual criou uma relação entre o retorno de cada uma das carteiras e o da carteira BAB. A previsão matemática, oriunda do modelo modificado, diz que o coeficiente desta relação é menor quanto maior for o beta. Foi possível levantar esta evidencia empírica de maneira clara. Este ponto foi o grande diferencial deste trabalho, uma vez que fomos os primeiros a levantar tal evidencia e a mostrar que as carteiras BAB podem ser utilizadas como variável explicativa.

Abstract:

This report covers a study testing the possibility of adding portfolio optimization by mean-variance analysis as a tool to extend the concept of momentum strategies in contrast to naive allocation formed by Jegadeesh & Titman (1993). Further these active investment strategies are compared with a passive benchmark as well as a randomly selected portfolio over the entire study-period. The study showed that the naive allocation model outperformed the mean-variance model both economically as well as statistically. No indication where obtained for a lagged return effect when letting a mean-variance model choose weights for a quarterly holding period and the resulting investment recommendation is to follow a naive investment strategy within a momentum framework.

Abstract:

Syfte: Studera sju portföljer och notera den bästa typen av portfölj med högst avkastning till lägst risk. Metod: Sekundärdata är grunden för uträkning av samtliga portföljers avkastningar, risker och korrelation. Studien är deduktiv med kvantitativa inslag av kända teorier av nobelpristagare i ekonomisk vetenskap. Slutsats: Studien visar att stora bolag i olika branscher är ett vinnande portföljinnehåll för denna studie. Stora bolags aktier har visat högre avkastning till lägre risk jämfört med små bolag under studiens tid då ekonomiska kriser drabbade marknaden. Den mest presterande portföljen var därför storbolagsportföljen. Vidare forskning: Längre tidsperspektiv och nya teorier som Jensens alfa samt Treynorkvot är av intresse för vidare forskning för att styrka vår slutsats.
Intention: To study seven portfolios and note the best type of portfolio with the maximum return at a minimum risk. Method: Secondary data is the basis for calculation of the total portfolio returns, risk and correlation. This study is deductive based using a quantitative method of world-known theories of Nobel laureates in economic sciences. Conclusion: The study shows that the best efficient portfolio contains large companies in different lines of business. Large companies' shares have higher returns at lower risk compared to small companies in circumstances to difficult economic situations globally. The best performed portfolio was the portfolio with large companies. Further Research: Longer period of time study and a study of new theories such as Jensens Alfa and Tretnor ratio would be interesting for further research.

Abstract:

Aim: Based on portfolio theory, which highlights diversification, and CSR, which describes the value of social and ethical responsibility of corporations, this study examines whether there is a difference in risk-adjusted performance between ethical and traditional mutual funds. Ethical funds are limited in their opportunities of diversification and should therefore be limited in their potential perfomance. On the other hand, a focus on social and ethical responsibility can be profitable. Method: The study uses a quantitative approach where we used 25 mutual fund in each category, ethical and conventional mutual funds. The mutual funds and their data has been obtained from www.morningstar.se and www.pensionmyndigheten.se. Historical performance between 2009-2013 were processed to obtain the Sharpe ratio and M2. For comparison a independent t-test is used. Result & Conclusions: Although ethical and traditional mutual funds have different diversification opportunities, the results indicate no significant difference in risk-adjusted performance between ethical and conventional funds.

Abstract:

The thesis examines the strategy of country momentum and is evaluated with 30 different country exchange-traded funds (ETFs) for the period 1996-2018. The empirical evaluation is designed to apply different formation- and holding periods with overlapping portfolios. The results show positive momentum returns in various periods and a few portfolios present a higher average return than the market. However, none of the portfolios is presenting any significant positive returns or alphas, meaning that the three hypotheses cannot be rejected. On the other hand, some portfolios have higher Sharpe ratios and Morningstar value than the market. Thus, meaning that the individual investor could prefer the momentum portfolio over the market despite the insignificant returns.
