About Stephen Mandel

Stephen Mandel founded Lone Pine Capital in 1997 after leaving Tiger Management, where he ran the consumer and retail book under Julian Robertson — making him one of the more prominent members of the Tiger Cubs lineage. His approach is concentrated long/short equity with a fundamental, bottom-up orientation, though Lone Pine has historically run both a hedge fund and a long-only vehicle, so a 13F captures only the long side of a book that may carry meaningful short exposure elsewhere. The current portfolio of 36 positions with roughly 30% in the top five — VST, ASML, CRS, LPLA, and APP — reflects a moderately concentrated stance tilted toward technology-adjacent growth and energy infrastructure. Readers should note that 13F filings trail reality by up to 45 days and omit short positions entirely; the long-only clone's roughly flat excess return versus SPY over 12 years is not a meaningful proxy for actual fund performance, which incorporates the short book, leverage, and more frequent repositioning.

2026Q2 brief

2026Q2 activity: 13 new positions (top: NEBIUS GROUP, SEAGATE TECH, HD); 6 conviction adds (top: MDLN, PFGC, NU); 15 exits (top: VST, TLN, CLH). Top 5 holdings: NEBIUS GROUP, ASML, SEAGATE TECH, HD, AMAT (31% of portfolio).
