Buffett has sung Cook's praise in the past, too. In his 2021 letter to Berkshire shareholders, he wrote, "Tim Cook, Apple's brilliant CEO, quite properly regards users of Apple products as his first love, but all of his other constituencies benefit from Tim's managerial touch as well."

During his recent meeting with Berkshire Hathaway shareholders, the 94-year-old Oracle of Omaha downplayed the market’s volatility. “What's happened in the last 30, 45 days, 100 days, whatever you want to call it, it's really nothing,” he said.
