Buffett's Investment Moves: Praises BYD and TSMC, Buys Japanese Trading Houses, Sells Stake in TSMC.

Despite selling shares of electric-car maker BYD and chip manufacturer Taiwan Semiconductor Manufacturing Co. (TSMC), Warren Buffett praised both companies, calling BYD "extraordinary" and TSMC a "fabulous enterprise." Berkshire Hathaway recently trimmed its holdings of BYD H shares to 10.9% from 11.13%, but Buffett said the company wasn't in a hurry to reduce that stake. He also took credit for Berkshire's investment in TSMC and said the decision to reduce its stake in the business by 86% in the fourth quarter resulted from concerns over geopolitical tensions between China and Taiwan.
