Titelbeschreibung

A one-of-a-kind reference guide covering the behavioral and statistical explanations for market momentum and the implementation of momentum trading strategies Market Momentum: Theory and Practice is a thorough, how-to reference guide for a full range of financial professionals and students. It examines the behavioral and statistical causes of market momentum while also exploring the practical side of implementing related strategies. The phenomenon of momentum in finance occurs when past high returns are followed by subsequent high returns, and past low returns are followed by subsequent low returns. Market Momentum provides a detailed introduction to the financial topic, while examining existing literature. Recent academic and practitioner research is included, offering a more up-to-date perspective. What type of book is Market Momentum and how does it serve a range of readers’ interests and needs? <ul> <li>A holistic market momentum guide for industry professionals, asset managers, risk managers, firm managers, plus hedge fund and commodity trading advisors</li> <li>Advanced text to help graduate students in finance, economics, and mathematics further develop their funds management skills</li> <li>Useful resource for financial practitioners who want to implement momentum trading strategies</li> <li>Reference book providing behavioral and statistical explanations for market momentum</li> </ul> Due to claims that the phenomenon of momentum goes against the Efficient Markets Hypothesis, behavioral economists have studied the topic in-depth. However, many books published on the subject are written to provide advice on how to make money. In contrast, Market Momentum offers a comprehensive approach to the topic, which makes it a valuable resource for both investment professionals and higher-level finance students. The contributors address momentum theory and practice, while also offering trading strategies that practitioners can study.

A THOROUGH, HOLISTIC INTRODUCTION TO A COVETED INVESTMENT STRATEGY Momentum investing is a topic of rigorous debate and endless study—with good reason. Returns on the order of 12% annually have been recorded by investors following short-to-medium-term market trends. Quantitative investment professionals and students of finance and economics require a solid understanding of the mechanisms underlying this fascinating strategy. Written by top quants in business and academia, Market Momentum addresses key questions such as: <ul> <li>What are the important momentum investment strategies across asset classes?</li> <li>What are the theoretical explanations of market momentum, from behavioural and mathematical viewpoints?</li> <li>How are risk and return structured in momentum investing?</li> <li>What have been the characteristics of effective real-world momentum portfolios?</li> <li>Which statistical techniques and machine-learning applications are suited to the strategy and in which markets?</li> </ul> Market Momentum goes well beyond the extant, practitioner-oriented literature to provide a thorough introduction to the strategy, incorporating the latest research to bring the subject fully up to date.
