As Berkshire Hathaway settled into a new era under CEO Greg Abel, the conglomerate sharply increased its exposure to technology and airlines during the first quarter. Berkshire more than tripled its stake in Alphabet and purchased over $2.6 billion worth of shares in Delta Air Lines after Abel formally took over as chief executive from Warren Buffett at the start of the year.
The company also exited or reduced several investments, including holdings in Visa, Mastercard, Domino's Pizza, Amazon and UnitedHealth Group. The moves came after the departure of Todd Combs late last year. Combs had been one of the two investment managers Buffett brought in to help oversee Berkshire’s portfolio.
