Streszczenie:

The problem associated with value shares is that they may remain undervalued for an extended period of time. Therefore, determining when to buy value shares has been the focus of many investors and academics. Studies have determined fundamentals provide valuable information when selecting shares while price momentum provides a decent timing indicator. This research examines a novel share selection approach which seeks to combine fundamentals with momentum to obtain a leading timing indicator.This research seeks to determine if the fundamental momentum indicator can successfully and consistentl

Streszczenie:

This dissertation investigates the long-term performance of momentum portfolios. Its results show striking asymmetries for winners and losers and imply potentially different causes for the winner and loser components of momentum. After separately examining winners and losers relative to their respective benchmark portfolios with no momentum, we find winner momentum is smaller in magnitude, persists only for six months, and its higher return fully reverses. This is consistent with the notion that winner momentum is an overreaction to positive news and potentially destabilizing. Loser momentum i

Value shares are notorious for remaining stagnant for extended periods of time, forcing value investors to remain locked in their investments often for excessive periods.

This thesis investigates momentum trading strategies during times of market turbulence. Momentum strategies have been shown to be profitable during multiple time periods in various equity markets and across different asset classes. However, one issue that momentum strategies face is the limited profitability during market downturns and the vulnerability to crashes. Another practical issue for momentum is the regulations on the short-side of its strategy during extreme economic conditions. As such, it is crucial to investigate and accurately interpret what drives momentum according to its vulne

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 rat

Researchers recommended investing according to the long only momentum (MOM) strategy to generate excess returns for private investors. The general problem of this study was that it was unclear when to enter and when to exit declining financial markets to avoid larger losses and to improve the overall performance with the MOM strategy. Therefore, it was important to understand the influence of a timing indicator on the MOM strategy. The purpose of this study was to examine the relationship between different moving average (MA) settings, the MOM strategy, and the performance of the returns from

The momentum puzzle, i.e., stocks that have performed better in the past tend to perform better in the future, has been a constant challenge to classic finance theory. Prior research has failed to provide valid risk-based explanations because winner portfolios do not exhibit higher risk characteristics. Without a convincing risk explanation, the persistence of momentum profit is a violation of the efficient market hypothesis. Today, the momentum puzzle remains one of the very few major anomalies that cannot be explained by Fama-French factor models. I find prior empirical efforts to measure mo

Since the seminal works of Markowitz (1952), Sharpe (1964), and Lintner (1965), numerous studies on portfolio selection and performance measure have been based upon the mean-variance framework. However, several researchers [e.g., Arditti (1967, and 1971), Samuelson (1970), and Rubinstein (1973)] argue that the higher moments cannot be neglected unless there is reason to believe that: (i) the asset returns are normally distributed and the investor's utility function is quadratic, or (ii) the empirical evidence demonstrates that higher moments are irrelevant to the investor's decision.

Le but de cette thèse est de construire un modèle de détection des changements de phase -passages de marché haussier à baissier et vice versa - du marché des actions américaines cotées, en utilisant un nombre relativement important de variables à la fois fondamentales (macroéconomiques et microéconomiques) et issues de l’analyse technique.Le modèle statistique retenu est la régression logistique statique, avec un retard pour les variables explicatives allant de zéro à trois mois. Les huit variables les plus significatives parmi vingt candidatesont été sélectionnées à partir des données mensuel

Um produto tensorial finito de densidades Erlang será usado para aproximar a densidade de probabilidade multivariada dos retornos discretos uniperiódicos de ativos dependentes. A Erlang é um caso particular da distribuição Gama. Uma mistura finita pode gerar densidades multimodais não-simétricas e o produto tensorial generaliza este conceito para dimensões maiores.

This paper aims to verify the persistence of the profitability of the Momentum strategy, first implemented by Richard Driehaus in the 1980’s. Furthermore, the paper will test the impact of changing several parameters of the strategy on its profitability. A combination of the Momentum strategy with a Value-oriented one will also be analyzed, with a view to assess the outperformance of this aggregate portfolio. The results are in line with Jedadeesh and Titman (2001), there is still evidence for its profitability in recent years, except in times of severe volatility. Additionally, there is

The momentum and carry anomalies have been extensively documented in the literature. However, there are still many issues relating to the risks associated to them that are left unexplained. One is the fact that an investor holds for too long the most volatile assets, both under momentum and carry strategies. Therefore, they present a level of risk and a probability of extreme events to happen inconsistent. This work project hypothesizes and proves the introduction of risk parity rules on the weights of the portfolios do increase risk rewarding of carry strategies. However, it fails under momen

Risk-managed portfolios that conditions exposure based on past realized volatility increases Sharpe ratios and yields high alphas that persists even after transaction costs. I find this for the market, value, momentum, profitability, investment, return on equity, and betting-against-beta. I offer a strategy that practically eliminates exposure to crashes and that can be easily implemented in real-time. As the strategy takes less risk during recessions it rules out classical risk-based explanations and challenges modelling of time-varying expected returns.<br>Carteiras geridas tendo em ate

This thesis tries to examine the turnover frequency of stocks in long-short portfolio of momentum strategy. Empirical results first provide the evidence that momentum strategy is profitable. Second, there are 39.21% (40.21%) winner (loser) stocks retaining their rankings in the next month based on six-month price return performances and the average turnover rate is 86.41% (87.73%) for winner (loser) portfolios in six-month/six-month momentum strategy.

Positive feedback trading is the most popular method which the institutions take their investing. It was introduced by Jegadeesh and Titman (1993) to use the underreaction of the investors to the news in the period of 3 to 12 months and get some profits by longing the past winners and shorting the past losers.
