Some of the outperformance — the S&P 500 returned 29% in the same time frame — was credited to none other than the Oracle of Omaha, Warren Buffett.
In 2019, Ackman bet big on Berkshire Hathaway, run by Buffett; in August, Berkshire Hathaway shares accounted for roughly 11% of the fund's net asset value, Ackman told investors.Those other bets included fast-food companies Starbucks and Chipotle, home-improvement retailer Lowe's, and hospitality company Hilton Worldwide Holdings.
