Semiconductor stocks are broadly lower in pre-market trading, continuing a sell-off from the previous session and weakness seen in Asian markets. The decline comes despite record earnings from industry bellwether Taiwan Semiconductor Manufacturing Co. (TSMC), suggesting a "sell the news" event. Investors appear to be taking profits amid concerns over high valuations after a significant AI-driven rally, with the bar for earnings set extremely high. The weakness is sector-wide, affecting memory chip makers and AI infrastructure stocks.
