Billionaire Bill Ackman's fund, Pershing Square, has generated a 15.9% annualized return since 2004. That track record beats the S&P 500 by over 5 points a year. A $1,000 investment with Ackman in 2004 would be worth over $25,000 today. In recent trading activity, Ackman sold 25% of his stake in a major technology firm for two AI competitors. He also introduced a fresh method to invest in pre-IPO companies.
Outside of market investments, Ackman contributed funds to a brain research center after his daughter suffered a hemorrhage.
