Taiwan-listed stocks can normally move at most 10% from the reference price — usually the previous close — in a session, and limit prices are rounded inward to the exchange tick, so TSMC’s NT$2,490 close (Oct 2026) implied a NT$2,245–2,735 band. Here is how limit-up queues, frozen quotes, and delayed price discovery actually work.
TWSE publishes securities-lending (借券) short balances for every shortable stock daily after the close — the institutional short channel, separate from retail margin shorts. Here is where to find the data, how to read a balance like TSMC’s 15.2 million borrowed-and-sold shares (Sept 2026), and why a rising balance is often consistent with hedging, not a bearish bet.
Taiwan’s benchmark set an all-time intraday high of 48,601 before heavy profit-taking pared the gain to 0.17%. Foreign investors still bought NT$44.73 billion of cash equities, while TSMC dragged and the ASIC and substrate complex ran to limit-up.
Taiwan’s benchmark eased to 46,940 on Thursday as foreign institutions sold a net NT$38.3 billion, breaking a four-session buying run. TSMC dipped despite a record August sales print, while MediaTek jumped 2%.
Taiwan’s benchmark gave back an early 250-point rally to close at 47,105.78 on Tuesday. TSMC held green at NT$2,470, but Hon Hai, MediaTek and UMC dragged electronics lower. Foreign investors bought NT$13.27B net while dealers sold NT$18.54B — a split tape ahead of Thursday’s monthly revenue filings.
Taiwan’s benchmark jumped 775 points to 47,326 on Monday as MediaTek soared 7.8% on AI ASIC momentum and UMC locked limit-up, with foreign investors pouring in NT$88.3 billion while US markets sat out Labor Day.
TWSE and TPEx publish every margin-eligible stock’s outstanding margin loans each evening for free, and once an account’s maintenance ratio falls below roughly 130% the broker issues a margin call — with forced selling following only if collateral is not restored by the deadline. Here is how to read Taiwan’s retail leverage data step by step — and why sharp margin contractions, not rising balances, tend to mark market bottoms.
Taiwan stocks fell 784 points on Wednesday, closing at the session low of 46,164.72 as US-Iran tensions and an overnight chip rout hit sentiment. Foreign investors sold a net NT$91.35 billion, while SEMICON Taiwan lifted equipment and silicon-photonics names limit-up against the tide.
Taiwan’s benchmark closed Tuesday at 46,948.72, up 1.78%, powered by a limit-up 9.94% surge in MediaTek and a NT$56.1B combined institutional bid — foreign investors, investment trusts and dealers all net buyers on the same day.
Foreign investors cannot simply open a Taiwan brokerage account the way locals do: you must first register with the TWSE as a FINI or FIDI — a filing handled through a locally appointed agent, which under current TWSE account-opening rules can be a securities broker or a custodian bank — and only then open a local broker account. Custody arrangements depend on your circumstances. Here is each step, what differs for individuals versus institutions, and the ADR/ETF alternatives if you skip it.
