$Taiwan Semiconductor(TSM.US)$ Yesterday, many people bought this stock and took it if they didn't see anything good. Be careful. Old Buffett's family is older, and he also has money. Everyone follows the investment, either fighting for a long time or taking it when it is good. If a stock can make a lot of money, the news won't reveal the news that senior management within the company is buying the stock; that is, hyping up the stock, and then falling.
