Warren Buffett (Trades, Portfolio)'s Berkshire Hathaway ( BRK.A , Financial) ( BRK.B , Financial) made some interesting changes to its portfolio in the second quarter of 2022. I say "Buffett's Berkshire" because it is not entirely clear if the Oracle of Omaha made all of the trades himself or if they were directed by one or both of the corporation's portfolio managers, Todd Combs and Ted Weschler.
