About Steve Mandel

**Steve Mandel / Lone Pine Capital**

Steve Mandel is the founder of Lone Pine Capital, a Greenwich-based long/short equity firm with a longstanding institutional presence in global equity markets. As of the Q1 2026 13F filing, dated May 15, 2026, the reported equity portfolio totaled approximately $12.5 billion spread across 36 disclosed positions, reflecting a focused and selectively concentrated allocation approach.

The latest filing identifies Vistra Corp (VST) as the largest reported position at 7.4% of the portfolio, followed by ASML Holding NV (ASML) at 6.9%, Carpenter Technology Corp (CRS) at 5.7%, LPL Financial Holdings (LPLA) at 4.9%, and AppLovin Corp (APP) at 4.7%. Collectively, the top five holdings represented 29.6% of the total disclosed portfolio. The filing categorizes 83.4% of the portfolio under an unclassified sector designation, with the remaining exposure distributed across other reported segments. The portfolio's construction is consistent with a sector rotation style, as reflected in the diversified composition of the top holdings across energy, semiconductors, specialty materials, financial services, and technology.

Quarter-over-quarter activity in Q1 2026 reflects a complete reset of disclosed positions: all 36 holdings were filed as new positions, with zero exits, zero increased positions, and zero reduced positions recorded. This pattern is consistent with either a full portfolio restructuring or a reporting methodology change between filing periods. No carryover positions from the prior quarter appear in the current disclosure.

All data sourced from SEC 13F filings.

Why this matters

Why a new position matters

Opening a new position can suggest the manager sees value or a thesis worth committing capital to. It does not necessarily mean they are bullish on the broader market — concentrated managers add positions infrequently while quants may rotate constantly.
