Global AI Company Stocks
Track daily prices for 20 leading AI/tech companies worldwide (US, Taiwan, China, Germany) — updated daily.
All prices shown in USD (including non-US-listed tickers like TSM/BABA/SAP — these are US-traded ADR prices, not local-exchange prices).
Why are some tickers moving more than 10%?
For large-cap stocks, a single-session move above 10% is rare and almost always comes with a volume spike from earnings, guidance changes, M&A, or major product news. When such a move isn't confirmed by volume, it's more likely a data issue — an unadjusted stock split/dividend, a currency mismatch, mixing ADR pricing with local-exchange pricing, a stale quote, or a timezone offset. This page flags moves automatically based on the rules above, with no speculative news attached — cross-check with official company disclosures before concluding anything.
