Book Synopsis The Vanishing Abnormal Returns of Momentum Strategies and 'Front-Running' Momentum Strategies by : Thomas Henker
Download or read book The Vanishing Abnormal Returns of Momentum Strategies and 'Front-Running' Momentum Strategies written by Thomas Henker and published by . This book was released on 2009 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: We find large variations in returns from momentum strategies. Momentum strategies did not earn significant returns during the period of 1993-2004 which was due to their poor performance over the period from 2001-2004. We find that the previously documented large firm momentum effect is sensitive to the momentum strategy examined, and is in our sample driven by the abnormal returns of large Nasdaq stocks. We also evaluate momentum strategies that do not adhere to the end of month portfolio formation universally used in the academic literature. To this end we form portfolios one week prior to the end of month and call them 'front-running' momentum portfolios. Consistent with institutional momentum trading affecting end of month returns and volatility, we find that 'front-running' a momentum strategy generates similar, but less volatile returns than the month-end strategy. Pertinently, the returns of a 'front-running' strategy are consistently less volatile than that of an equivalent month-end strategy.
Book Synopsis Momentum and Reversal Dynamics by : James W. Kolari
Download or read book Momentum and Reversal Dynamics written by James W. Kolari and published by . This book was released on 2019 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper studies the joint dynamics of momentum and reversal strategies in the U.S. stock market. Momentum investors face uncertainty about whether past patterns of price movements will continue (momentum) or reverse, thereby increasing volatilities of momentum returns and occasionally leading to momentum crashes. We find that the forces that drive reversal over momentum tend to be strong if losers' past return is extremely low in the time series or if losers are small and illiquid in the cross section. Consequently, we propose new risk-managed momentum strategies that take into account the behavioral divergence between momentum and reversal. Empirical tests for the U.S. stock markets in the sample period of 1947 to 2015 document that momentum strategies in which investors implement stop-trading rules if losers' past returns are extremely low as well as buy-small-loser rules substantially outperform traditional momentum strategies. Importantly, we find that the outperformance is mainly attributable to the increase in abnormal returns (or alpha) from various factor models.
Book Synopsis Momentum Style Investing by : Mazen Mohamed Stetie
Download or read book Momentum Style Investing written by Mazen Mohamed Stetie and published by . This book was released on 2010 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: An ample amount of work has been done on trading strategies that can be traced back more than 100 years. Trading strategies attempt to generate abnormal returns that exceed the tradeoff between risk and return as modeled in classical finance theories. Among these, momentum trading strategies take positions on financial assets in a way that assumes that past trends will continue over the short term (less than 1 year). The most important indicative criteria for momentum strategies have been past return (price) and earnings forecasts. This project investigates another criterion which is the skewness of past daily stock returns. The results show that negative (positive) skewness over a short past horizon of six months leads to a positive (negative) expected change in returns over the future horizon of same period. Moreover, for the same past and future horizons, the combination of skewness and return as momentum indication criteria is discovered to outperform return as a sole criterion.
Book Synopsis Are Anomalies Still Anomalous? An Examination of Momentum Strategies in Four Financial Markets by : Daxue Wang
Download or read book Are Anomalies Still Anomalous? An Examination of Momentum Strategies in Four Financial Markets written by Daxue Wang and published by . This book was released on 2009 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we test the profitability of momentum strategies in the United Kingdom, Germany, Japan, and China over the period 1991 to 2006 and sub-periods. Both RSS (Relative Strength Strategies) and WRSS (Weighted Relative Strength Strategies) are used to form the momentum portfolios. As a result, we find that the United Kingdom and Germany exhibit rather stable medium-term return continuation for both RSS and WRSS over the entire sample period and sub-periods, while Japan shows a medium-term return reversal over the sub-period 1991-1998. As for China, we report momentum profits over the period 1995-2006 and the sub-period 2001-2006 with RSS. Furthermore, we use the results of RSS to check the influence of risk factors and transaction costs on the momentum returns, as well as calendar effects and other characteristics of momentum portfolios reported in the literature. With the results of WRSS, we examine the relative importance of time-series predictability and cross-sectional variation in accounting for the profits of momentum strategies.
Book Synopsis The Illusory Nature of Momentum Profits by : David A. Lesmond
Download or read book The Illusory Nature of Momentum Profits written by David A. Lesmond and published by . This book was released on 2004 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: In markets with trading friction, the incorporation of information into market prices can be substantially delayed through a weakening of the arbitrage process. We re-examine the profitability of relative-strength, or momentum, trading strategies (buying past strong performers and selling past weak performers). We find that standard relative-strength strategies require frequent trading in disproportionately high-cost securities so that trading costs prevent profitable strategy execution. In the cross section, we find that those stocks that generate large momentum returns are precisely those stocks with high trading costs. We conclude that the magnitude of the abnormal returns associated with these trading strategies creates an illusion of profit opportunity when, in fact, none exists.
Book Synopsis Are Momentum Strategies Feasible in Intraday-Trading? Empirical Results from the German Stock Market by : Tim Alexander Herberger
Download or read book Are Momentum Strategies Feasible in Intraday-Trading? Empirical Results from the German Stock Market written by Tim Alexander Herberger and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Momentum trading strategies have been proved to be profitable in different asset classes and on various national capital markets in the past. However, there are some indications for eroding momentum profits. Based on the theory of gradual information distribution on capital markets and the technological progress of the last years, we suppose that the momentum effect transformed from a monthly basis to shorter time horizons. With regard to stocks that were listed in the German blue chip index DAX 30 between November 2013 and December 2014, this study is the first to examine, whether such strategies generate market adjusted excess returns on an intraday-trading basis. We analyze 16 momentum strategies, inspired by Jegadeesh/Titman (1993) and Jegadeesh/Titman (2001) original momentum strategy design (4x4), with ranking and holding periods of 15, 30, 45 or 60 minutes. For each stock, we analyze 27,219 price observations on a five minutes frequency. From the empirical results we conclude that momentum strategies do not provide positive excess returns. However, we find indications for price reversals in intraday stock market returns for past loser stocks. Our results are robust on portfolio size (winner as well as loser-portfolio), on the duration of the lag between the ends of the formation ranking periods and the beginnings of the holding periods as well as on the influence of trading-time or on the market price trend.
Book Synopsis Three Essays on Momentum by : Jun Wang
Download or read book Three Essays on Momentum written by Jun Wang and published by . This book was released on 2010 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essay 1, Growth/Value, Market-Cap, and Momentum, examines the profitability of style momentum strategies on portfolios based on firm growth/value characteristics and market capitalization. We use monthly total returns of nine S & P style indices to avoid concerns about firm size, liquidity, credit risk, short-sale constraints, and transaction costs. We find that historically buying a past best performing style index and short-selling a past worst performing style index generates economically and statistically significant profit of 0.8% per month over the period June 1995 to March 2009. This profitability remains economically plausible after adjusting for systematic risk, short-sale costs, and transaction costs. Investors may actually implement style momentum strategies on exchange traded funds linked to the S & P style indices. Essay 2, Sector Momentum, examines monthly returns of nine Select Sector SPDRs and finds historically buying past outperforming sectors and selling past underperforming sectors produces economically and statistically significant profits. Investors may be able to not only benefit from SPDRs' low fees, tax efficiency, and trading flexibility, but also exploit SPDRs as asset allocation tools to earn excess returns on sector momentum. For robustness checks, I test sector momentum investing strategies on CRSP listed individual stocks between January 1963 and December 2008 using Global Industry Classifications Standard (GICS) and also find statistically significant payoffs. Essay 3, Momentum Strategies on Global ETFs, examines the price momentum on 15 well-diversified iShares MSCI Country Index ETFs from April 1996 to December 2006. I find statistically and economically significant profits for some momentum strategies: long past winners and short past losers. The results are robust to trading costs and excessive risks.
Book Synopsis Momentum Trading, Return Chasing, and Predictable Crashes by : Benjamin Chabot
Download or read book Momentum Trading, Return Chasing, and Predictable Crashes written by Benjamin Chabot and published by . This book was released on 2014 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: We combine self-collected historical data from 1867 to 1907 with CRSP data from 1926 to 2012, to examine the risk and return over the past 140 years of one of the most popular mechanical trading strategies -- momentum. We find that momentum has earned abnormally high risk-adjusted returns -- a three factor alpha of 1 percent per month between 1927 and 2012 and 0.5 percent per month between 1867 and 1907 -- both statistically significantly different from zero. However, the momentum strategy also exposed investors to large losses (crashes) during both periods. Momentum crashes were predictable -- more likely when momentum recently performed well (both eras), interest rates were relatively low (1867-1907), or momentum had recently outperformed the stock market (CRSP era) -- times when borrowing or attracting return chasing "blind capital" would have been easier. Based on a stylized model and simulated outcomes from a richer model, we argue that a money manager has an incentive to remain invested in momentum even when the crash risk is known to be high when (1) he competes for funds from return-chasing investors and (2) he is compensated via fees that are convex in the amount of money managed and the return on that money.

Download or read book The Handbook of Equity Market Anomalies written by Leonard Zacks and published by John Wiley & Sons. This book was released on 2011-08-24 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investment pioneer Len Zacks presents the latest academic research on how to beat the market using equity anomalies The Handbook of Equity Market Anomalies organizes and summarizes research carried out by hundreds of finance and accounting professors over the last twenty years to identify and measure equity market inefficiencies and provides self-directed individual investors with a framework for incorporating the results of this research into their own investment processes. Edited by Len Zacks, CEO of Zacks Investment Research, and written by leading professors who have performed groundbreaking research on specific anomalies, this book succinctly summarizes the most important anomalies that savvy investors have used for decades to beat the market. Some of the anomalies addressed include the accrual anomaly, net stock anomalies, fundamental anomalies, estimate revisions, changes in and levels of broker recommendations, earnings-per-share surprises, insider trading, price momentum and technical analysis, value and size anomalies, and several seasonal anomalies. This reliable resource also provides insights on how to best use the various anomalies in both market neutral and in long investor portfolios. A treasure trove of investment research and wisdom, the book will save you literally thousands of hours by distilling the essence of twenty years of academic research into eleven clear chapters and providing the framework and conviction to develop market-beating strategies. Strips the academic jargon from the research and highlights the actual returns generated by the anomalies, and documented in the academic literature Provides a theoretical framework within which to understand the concepts of risk adjusted returns and market inefficiencies Anomalies are selected by Len Zacks, a pioneer in the field of investing As the founder of Zacks Investment Research, Len Zacks pioneered the concept of the earnings-per-share surprise in 1982 and developed the Zacks Rank, one of the first anomaly-based stock selection tools. Today, his firm manages U.S. equities for individual and institutional investors and provides investment software and investment data to all types of investors. Now, with his new book, he shows you what it takes to build a quant process to outperform an index based on academically documented market inefficiencies and anomalies.
Book Synopsis Using Volatility to Improve Momentum Strategies by : Omar Khlaif Gharaibeh
Download or read book Using Volatility to Improve Momentum Strategies written by Omar Khlaif Gharaibeh and published by . This book was released on 2016 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper attempts to enhance momentum strategy by using volatility effect. To achieve this objective, double sorting portfolio is used and data is collected from 10 Arabic market indices over the period of 1990-2014. A simple modification to the traditional momentum strategy provides highly profitable results in Arabic market indices. While traditional momentum alone provides significant abnormal raw return of 1.16% per month over the six-month holding period, new momentum strategy based on double sort suggested by this study represented via recent winners with low-volatility outperform recent losers with high-volatility and it provides significant abnormal raw returns of 2.60% per month over the same holding period. Finally, either traditional momentum or momentum with volatility strategies can't be explained by two factor model.
Book Synopsis Feasible Momentum Strategies - Evidence from the Swiss Stock Market by : David M. Rey
Download or read book Feasible Momentum Strategies - Evidence from the Swiss Stock Market written by David M. Rey and published by . This book was released on 2013 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: While there is little controversy on the profitability of momentum strategies, their implementation is afflicted with many difficulties. Most important, chasing momentum can generate high turnover. Though there are already several attempts to make momentum strategies less expensive with respect to transaction costs, we go a step further in the simplification of momentum strategies. By restricting our sample to Switzerland's largest blue-chip stocks and choosing only one winner and one loser stock, we find average returns to our momentum arbitrage portfolios of up to 44% p.a. depending on the formation and holding periods. While unconditional risk models are at odds with momentum profits, stock market predictability and time-varying expected returns explain a large part of the momentum payoffs, including the post-holding period behavior of the winner and loser stocks (overreaction and subsequent price correction). We also report interesting patterns of a number of stock characteristics over the (pre-)formation and (post-)holding periods.
Book Synopsis Risk-Adjusted Cross-Sectional Momentum by : Myeong Hyeon Kim
Download or read book Risk-Adjusted Cross-Sectional Momentum written by Myeong Hyeon Kim and published by . This book was released on 2017 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study proposes a new ranking criterion for constructing momentum portfolios, namely, risk-adjusted cross-sectional momentum. We propose the combination of traditional cross-sectional momentum strategies with different volatility timing strategies in the form of the Sharpe ratio. Then, we show that the traditional momentum trading is inferior to the risk-adjusted cross-sectional momentum strategy and employing the conditioning information can be beneficial with 3% annual returns. This finding is particularly pronounced in the presence of momentum crashes during the global financial crisis. In addition, we highlight the role of penny stocks and find that they significantly affect momentum crashes. Our findings have important implications for market practitioners.
Download or read book Momentum Strategies written by Sonia Azri and published by . This book was released on 2017 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: We examine the profitability of momentum strategies in the Tunisian stock market over the period (January 1998-December 2007). We adopt the methodology of Jegadeesh and Titman (1993). The results show that momentum strategies are profitable. We use the methodology of Lo and Mackinlay (1990) and the methodology of Jegadeesh and Titman (1995) to decompose the profits. The results confirm the hypothesis of risk's recompense of profits. The profitability of momentum strategies not implies the inefficiency of stock market. It than implies the failure of stock pricing model. However, we find that the addition of the momentum factor and a sentiment variable to three factor model of Fama and French, improves the chronological description of portfolio returns.
Book Synopsis The Efficient Market Theory and Evidence by : Andrew Ang
Download or read book The Efficient Market Theory and Evidence written by Andrew Ang and published by Now Publishers Inc. This book was released on 2011 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Efficient Market Hypothesis (EMH) asserts that, at all times, the price of a security reflects all available information about its fundamental value. The implication of the EMH for investors is that, to the extent that speculative trading is costly, speculation must be a loser's game. Hence, under the EMH, a passive strategy is bound eventually to beat a strategy that uses active management, where active management is characterized as trading that seeks to exploit mispriced assets relative to a risk-adjusted benchmark. The EMH has been refined over the past several decades to reflect the realism of the marketplace, including costly information, transactions costs, financing, agency costs, and other real-world frictions. The most recent expressions of the EMH thus allow a role for arbitrageurs in the market who may profit from their comparative advantages. These advantages may include specialized knowledge, lower trading costs, low management fees or agency costs, and a financing structure that allows the arbitrageur to undertake trades with long verification periods. The actions of these arbitrageurs cause liquid securities markets to be generally fairly efficient with respect to information, despite some notable anomalies.
