Taiwan's stock market suffered one of its worst days ever, dragged down by a global tech sell-off, and it's bad news for investors and major chipmakers.

• Taiwan's main index crashed more than 1,600 points intraday, the 11th-biggest intraday drop in its history, breaking below both the 46,000 and 45,000 levels.
• The rout wiped out over NT$5 trillion in market value in a single day, roughly equal to the entire value of Foxconn or Delta Electronics.
• The trigger was a global tech sell-off after weak earnings from Google, Amazon, and Intel, plus a drop in the Nasdaq and U.S. semiconductor index overnight.
• Key Taiwanese companies got hit hard: Delta Electronics fell over 9% on weak earnings tied to AI data-center supply bottlenecks, and panel maker AUO swung to a loss and dropped more than 9%.
• High U.S. inflation data raised fears the Fed may hike rates again, which also pushed gold prices down.

Outlook: With U.S. tech earnings and Fed rate worries still weighing on sentiment, more volatility is likely in the near term, though some analysts still see buying opportunities in beaten-down chip and component stocks.
