Links theory and practice for investment professionals and portfolio managers, demonstrating why some portfolios consistently perform better than others Investing well, like any other business, depends on competitive advantage. Some portfolios reliably generate greater returns than others because they simply are better positioned to benefit from strengths and avoid weaknesses. Building and using competitive advantage becomes central to the daily work of the best mutual funds, hedge funds, banks, insurers and virtually every other type of portfolio. But competitive advantage commonly is overlooked in most written work for investment professionals. The literature often varies between abstract formal treatments and pragmatic workbooks with little in between. Competitive Advantage in Investing fills the gap by integrating modern portfolio theory with actual practice in one comprehensive volume. This innovative book guides investment professionals on building and sustaining competitive advantage and helps policymakers and researchers apply theory in a wide range of practical settings. Author Steven Abrahams—Senior Managing Director at Amherst Pierpont Securities and former Adjunct Professor of Finance and Economics at Columbia Business School—draws from his experience in both academic theory and real-life strategic investing to bridge the two worlds.
