Steve Mandel

Steve Mandel graduated from Dartmouth College and earned an MBA from Harvard Business School. He spent a decade in consumer products and retail equity research before joining Julian Robertson's Tiger Management. At Tiger he developed deep expertise in consumer and retail equity analysis under Robertson's demanding mentorship. When Robertson closed Tiger in 2000, Mandel had already founded Lone Pine Capital in 1997 with an initial stake from Robertson. Lone Pine pursued a concentrated long-short equity strategy focused on high-quality businesses with sustainable competitive advantages and exceptional management teams. The fund earned a reputation for superior due diligence and exceptional long-term risk-adjusted returns — consistently generating 20%+ annualised performance over its first two decades while maintaining disciplined risk management and low drawdowns. Mandel was known for building extremely concentrated positions in his highest-conviction ideas, holding them patiently through market volatility. Unlike some of his Tiger Cub peers, Mandel kept Lone Pine focused on traditional long-short equity without expanding aggressively into venture or private investments. He stepped back from day-to-day management in 2019 while remaining a significant presence at the firm. Lone Pine continues to rank among the most highly regarded fundamental long-short equity hedge funds globally.
