Based on the geopolitical conditions between China and Taiwan, this is the right move by Buffett. A survey showed that half of US firms in Taiwan expect their business to be disrupted by Chinese military operations, and many companies are adding “risk clauses” to their contracts in Taiwan to protect against a flare-up between the island and the mainland.
Buffett is best known for his success in investing, but his decision to pull out is premature. TSMC continues to have a stranglehold on the semiconductor industry, with many companies depending on its technology, despite the current geopolitical tensions. While he's right to be concerned, this is one decision he may come to regret. Other investors would be wise to take advantage of TSMC’s projected success.
