Warren Buffett says the unusually quick sale of Berkshire Hathaway's TSMC stake was driven by geopolitical tensions

• Warren Buffett said geopolitical tensions were a factor behind Berkshire Hathaway's unusually quick sale of Taiwan Semiconductor.
• Berkshire Hathaway purchased $4.1 billion of TSMC stock in the third quarter of 2022, but sold nearly 90% of the position a few months later.
• Tensions between China and Taiwan have been building as US political figures visit the island in a show of solidarity.

Warren Buffett did something rather unusual last year when his conglomerate, Berkshire Hathaway, purchased a $4.1 billion stake in Taiwan Semiconductor in the third quarter of 2022.
