Taiwan's stock market sank hard today, with cooling-tech makers Jian Ce and Shuang Hong both hitting limit-down — bad news for Taiwan's AI supply chain, though some analysts see it as a buying chance.

• Jian Ce and Shuang Hong, both key suppliers of liquid-cooling parts for Nvidia's chips, got dumped as investors took profits after their big earlier run-up.
• Alphabet's latest earnings spooked markets over heavy AI spending, wiping huge value off its stock and dragging down Taiwan's tech names too.
• US midterm elections handed Democrats control of Congress; fears of tougher AI oversight hit chip stocks hard, even as the Dow jumped on hopes a divided government means fewer policy swings.
• Taiwan's main index is now down 16% from its record high, sparking margin calls and panic selling, but one well-known analyst is buying the dip on TSMC and raising his stock holdings, betting a bottom is close.
• Separately, Taiwan's central bank raised the loan limit for second homes, giving the housing market a lift, while GDP growth is set to hit a strong year even though wages for most workers aren't keeping up.

Outlook: Expect more sharp swings in cooling and chip stocks as the market weighs AI regulation worries against the still-strong long-term demand for liquid cooling.
