Berkshire Hathaway more than tripled the size of its investment in Google's parent company and bought over $2.6 billion worth of Delta Airlines stock as Greg Abel settled into the CEO job after taking over from Warren Buffett at the start of the year.
The conglomerate also dumped a number of other stocks, including Visa, Mastercard, Domino's Pizza, Amazon and United Healthcare after the departure late last year of Todd Combs, who was one of the two investment mangers Buffett hired to help manage the portfolio.
