Full textEsta dissertação tem como objetivo testar a hipótese de passeio aleatório na curva das yields relativa ás obrigações do tesouro dos Estados Unidos da América para o period entre 1980 e 2014. Para alcançar este objetivo e após revisão da literatura foram efectuados testes de variância e de raiz unitária considerados os mais indicados e poderosos. Os dados necessários para a realização deste estudo foram recolhidos tendo por base um estudo da Reserva Federal dos Estados Unidos da América, que efectua cálculo das yields desde 1961 até ao presente. O método escolhido para obter os resultados referentes à raiz unitária foi o Augmented Dickey-Fuller Unit Root Test e para os testes de variância foram usados: Chow Denning (1993) multiple variance test, Joint wright multiple version of Wrights rank and sign tests e Choi (1999) Automatic Variance ratio. A amostra inclui mais de 8000 observações para cada uma das yields estudadas(1,5,10 e 20 anos Zero-Coupon e Par Yields) durante um período de 34 anos. Os resultados permitiram a detecção de diversos periodos em que o passeio aleatório nas yields das obrigações do tesouro Norte-Americano é real mas também outros em que isso não se verificou. Para isso efectuámos uma análise comparativa entre os resultados dos testes de variância e eventos marcantes na economia americana entres os quais decidimos destacar 3 períodos: a década de 80, a expansao económica dos anos 90 até inicio do século XXI e o pós-crise de 2008 onde é implementado o quantitative Easing.
The random-walk hypothesis in the U.S. treasury yield curve was not previous studied and is surprising that researchers do not filled that void by testing it. However, the U.S treasury securities market is a benchmark, as the U.S treasury is considered to be risk-free. This benchmark is used to forecast economic development, to analyse securities in other markets, to price other fixed-income securities and to hedge positions taken in other markets. This study applies Chow Denning (1993) multiple variance test, Joint wright multiple version of Wright?s rank and sign tests, Choi (1999) Automatic Variance ratio Test and we also use the well-known Augmented Dickey-Fuller unit roots test to enable us to define the methodology to be used in the study. The database used permits the estimation of relative daily variation on U.S. treasury yield curve from January 1980 to December 2014. We hope that this analysis can provide useful information to traders and investors and will make a contribution in assisting to understand the pattern and behaviour of yields movement.

Full textIn 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 textHedge 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.
