Warren Buffett is losing control of Berkshire Hathaway, and hedge fund manager Bill Ackman says it’s time for a new era. The 94-year-old “Oracle of Omaha” has led Berkshire for decades, but Bill believes his investment style is outdated.

Warren Buffett is responsible for putting up tremendous returns as CEO of Berkshire Hathaway. But maybe his most lucrative bet came in the past decade, when the conglomerate purchased shares in a business that has put up a monster 900% total return since the start of 2016 (as of March 4).

The last time Berkshire aggressively bought stocks was in early 2022 when the S&P 500 was 20% below current levels.
