TSMC renewed its record at NT$2,585, United Daily reported; a large trade 'pointed the way' and drove the Taiex toward 48K.

TSMC concentrates demand for advanced processes and hopes for AI-chip foundry work. With a large weight in market cap, its price can sway the whole index.

The 'bellwether effect' and concentration

The 'bellwether effect'—one stock lifting the index—is powerful but also magnifies the risk of the market crowding into a single stock or sector; the gap with non-chip sectors is a variable.

With foreign and institutional buying continuing, some warn of short-term overheating. Global chip conditions and exchange rates will steer the trend.

For Chinese investors

TSMC and Taiwan's market are familiar assets to Chinese investors in Korea, Hong Kong and Southeast Asia. Yet record runs bring greater volatility, so diversification and risk management matter more than leaning on one expectation; the decision rests with the individual.

Experts advise watching the durability of earnings and demand rather than whether the index clears a 'psychological line.'
