Taiwan's stock market is mostly AI supply chain.
Seven AI stocks make up 42% of the iShares MSCI Taiwan ETF $EWT, and TSMC $TSM alone is 22%.
So when chip stocks had their second-worst day since 1994 on Thursday, Taiwan had its worst.
TSM's US shares fell 10.8%, and EWT fell 11.5%, its biggest drop since it started trading in 2000.
