William Sharpe

William Sharpe is an American economist and Nobel laureate best known for developing the Capital Asset Pricing Model (CAPM) and the Sharpe ratio, fundamental concepts in modern portfolio theory and investment management. His groundbreaking work at Stanford University in the 1960s revolutionized how investors and financial professionals analyze risk-adjusted returns. The Sharpe ratio, introduced in 1966, provided a standardized measure to compare investment performance while accounting for risk. Sharpe served as president of the American Finance Association and maintained an influential academic career at Stanford University's Graduate School of Business. His 1990 Nobel Prize in Economic Sciences, shared with Harry Markowitz and Merton Miller, recognized his contributions to the theory of financial economics. Beyond his theoretical work, Sharpe founded Financial Engines, an investment advisory firm that applied his academic principles to provide automated portfolio management services. His textbook "Investments" became a standard reference in business schools and financial institutions worldwide.
