Active 130/30 Extensions is the newest wave of disciplined investment strategies that involves asymmetric decision-making on long/short portfolio decisions, concentrated investment risk-taking in contrast to diversification, systematic portfolio risk management, and flexibility in portfolio design. This strategy is the building block for a number of 130/30 and 120/20 investment strategies offered to institutional and sophisticated high net worth individual investors who want to manage their portfolios actively and aggressively to outperform the market.

Klappentext
Modern Portfolio Management
"Investment professionals know that performance is determined not just by their overweights, but also by the positions that they choose to underweight." With this brief statement, Martin Leibowitz captures the essence of what both institutional and individual investors must accomplish for active risk-taking to achieve superior results.
In Modern Portfolio Management, Leibowitz and his coauthors offer new strategies for institutional investors who want to manage their portfolios more actively by using 130/30 investment techniques. The 130/30 framework is a natural extension of the basic long-only benchmark- relative strategy that is so widely practiced. This approach seeks to exploit the opportunities that exist between the more efficient long only market and the less efficient short market. This book shows how 130/30 strategies allow asset owners and asset managers to more fully exploit an active manager's information set. The in-depth ideas presented in this volume also go well beyond the strict confines of 130/30's to shed important new light on other types of active management, including fundamental and quantitative long-only as well as the various forms of more flexible long/short funds. Modern Portfolio Management offers institutional investors many insights and exciting new ways to think about alpha generation.
