Central News Agency (CNA) The anticipation of TSMC's earnings call has spurred the Taiwan stock market, which surged over a thousand points in early trading today. While the gains narrowed and the market fluctuated, it largely maintained a battle around the 47,000-point mark. In the final trading session, TSMC's stock price rallied, closing at the day's highest point of NT$2,505.
