Wholly owned businesses under the Berkshire umbrella, including GEICO, Precision Cast Parts, and even See's Candies felt the force of the COVID-19 impact. Seeing as the man couldn't have disposed of such businesses, given Berkshire's limited agility to respond to the slate of new risks, Warren Buffett did the next best thing by making big changes to his portfolio, ridding it of vulnerable airline stocks and loading up on defensive plays, including gold miner Barrick Gold and grocery stocks. More recently, Buffett trimmed his stake in Barrick, but I still think he's playing it cautious, with bets on a handful of healthcare stocks and cheap Japanese trading companies.
