Charles D. Ellis

"Investment consultant whose tennis analogy reshaped how the world thinks about active management."

Charles D. Ellis is an investment consultant, author, and former managing partner of Greenwich Associates, the institutional investment research firm he founded in 1972. Over a five-decade career he advised many of the world's largest investment institutions and served on the investment committees of Yale University and other major endowments, working alongside legendary investor David Swensen. His 1975 Financial Analysts Journal paper "The Loser's Game" became one of the most influential essays in the history of investment management, laying the intellectual groundwork for the shift toward low-cost index investing. Ellis has written more than 20 books on investing and institutional management, and Winning the Loser's Game, first published in 1985 and now in its eighth edition, remains one of the most widely read books on long-term investing.
