In a significant portfolio shift, Stephen Mandel's Lone Pine Capital completely sold off its stake in power generation company Vistra Corp. According to a recent SEC filing, the fund no longer held any of its 6.19 million shares as of June 30, 2026. The position was previously valued at approximately $930.18 million and represented a substantial 7.42% of the fund's reported portfolio in the prior quarter.
Investors should note that 13F filings are released with a delay, reflecting positions held at the end of the previous quarter, not necessarily current holdings. The exit is noteworthy as Vistra had been a top conviction bet for the prominent Tiger Cub fund. Lone Pine's move comes after Vistra's stock experienced a significant surge in value over the past couple of years.
