Stephen Mandel Jr.

Stephen Mandel Jr. worked at Tiger Management under Julian Robertson and was considered one of his best analysts, with deep expertise in consumer and retail sectors. He founded Lone Pine Capital in 1997, building it into one of the most respected long/short equity hedge funds globally, managing tens of billions of dollars at its peak. Lone Pine was known for fundamental research, global perspective, and a disciplined long/short approach. Mandel stepped back from day-to-day management in 2019, transitioning leadership to his team. His career exemplified the Tiger Cub generation — analysts trained by Robertson who went on to found successful firms carrying forward the fundamental research culture of Tiger Management. The smooth transition of management at Lone Pine following his retirement reflected the durable institutional culture he had built across two decades of disciplined investing.
