The client of Chinanews.com, May 3, May 3, Beijing time, Berkshire Hathaway chairman Buffett said that he is not optimistic about airlines and aircraft manufacturers. The epidemic has an impact on many industries. I particularly doubt whether the market will require so many aircraft after the epidemic. I do n’t know what the future of Boeing and Airbus will be. He also said that the stocks of the four major US airlines (American Airlines, Delta Air Lines, Southwest Airlines and United Airlines) would all be sold. In early April, Buffett had reduced its shares in Delta Air Lines and Southwest Airlines.
