Warren Buffett’s highly anticipated annual meeting is set to take place this weekend, and investors are eager to hear the legendary investor’s insights on recent moves in Berkshire Hathaway’s equity portfolio. One surprising move was the sale of 10 million Apple shares in the fourth quarter, slightly reducing the conglomerate’s massive stake in the tech giant. Buffett’s deputies may have made the move to fund other purchases, as they did in 2018. Another possibility is that the sale was prompted by Apple’s rising stock price or a desire to diversify the portfolio. Buffett may also reveal the identity of the mystery bank stock that Berkshire has been buying for two quarters straight. The conglomerate’s cost basis for bank stocks has risen significantly, and it’s relatively rare for Berkshire to request confidentiality for its purchases. Other topics likely to be discussed at the meeting include Berkshire’s aggressive buying of SiriusXM tracking stock and its recent loss-making bet on Paramount Global.
