Do geopolitical tensions over Taiwan drive investors to cut chipmaker stakes?
Core argument: Berkshire Hathaway cut its stake in Taiwan Semiconductor Manufacturing Co. by 86% in the fourth quarter, a sale that could have fetched $3.7 billion assuming shares were sold at the period's average price.
The billionaire investor took credit for Berkshire’s investment in TSMC amid speculation that one of his investing deputies picked the stock. He said the decision to reduce its stake in the business by 86% in the fourth quarter—which could have fetched $3.7 billion assuming the shares were sold at the average price over the period—resulted from concerns over geopolitical tensions between China and Taiwan, conditions he described as being outside of the company’s control. “I re-evaluated that part of it,” Buffett said. “I didn’t re-evaluate the business, the management, or anything of the sort.”
