Taiwan Stocks Jump 4.9% as Short-Selling Curbs End a 7-Day Slide
Direct answer
Taiwan’s stock market bounced back sharply on Monday, November 9, 2026. The Taiex index closed up 4.94% at 41,661.70, its biggest one-day gain since July 31, after regulators stepped in to slow down short selling and prepared a state fund to support the market.
What happened
The rebound came after a brutal week. The Taiex had fallen 12.19% in the week ended November 6, its steepest weekly drop since the week of the September 11 attacks in 2001, and it had lost ground for seven sessions in a row, the longest losing run since 2022. On Friday, November 6, the index closed at 39,701.64 after falling 4.51% in a single day.
Over the weekend, Taiwan’s Financial Supervisory Commission announced new rules that took effect on Monday. The daily limit for intraday short-sale orders using borrowed shares was cut to 3% of a stock’s average daily trading volume over the previous 30 sessions, down from 30%. The minimum margin required for short sales was raised to 130% from 90%, which makes it more expensive to bet against a stock.
At the same time, Taiwan’s National Financial Stabilization Fund was authorized to step in if needed. The fund has NT$500 billion, about $15.2 billion, available to buy shares, and this is its tenth market support operation since it was set up in 2000. The authorization alone does not prove the fund bought shares on Monday. It simply means the money is ready to use.
The market responded at once. The Taiex rose as much as 6.4% during the session before closing up 1,960.06 points. Trading was heavy, with turnover of NT$837.93 billion. Chip giant TSMC, the biggest stock in the index, rose about 4.7%. Other Asian markets rose too, with the MSCI Asia Pacific index up 2.3%.
The sell-off that came before this bounce had a clear trigger. Investors worried that the Democrats’ sweeping win in the United States midterm elections could slow down data-center construction, which would cut demand for the chips that Taiwan makes. That fear hit chip stocks across Asia last week.
Why it matters for beginners
Short selling is when traders borrow shares, sell them, and hope to buy them back cheaper later. When a market falls fast, short selling can add to the selling pressure. By making short selling harder and more costly, regulators removed one source of downward pressure. That is why the market bounced so hard.
A stabilization fund is a government-backed pool of money that can buy shares when a market falls in a disorderly way. Think of it as a safety net, not a guarantee. It can steady prices, but it cannot fix the real worries behind a sell-off, such as weaker demand for chips.
One strong day does not erase a bad week. Even after Monday’s 4.94% gain, the Taiex is still well below where it stood before last week’s slide. A single-day rebound is a reaction, not a recovery, until the market holds its gains over several days. This is the same lesson as in our guide to what risk means in investing: sharp falls can be followed by sharp rises, and both can happen fast.

What to watch next
TSMC reports its October revenue on Tuesday, November 10. That number will say more about real chip demand than one day of index movement. Investors will also watch the United States October inflation report, due the same day, for clues on interest rates. If chip demand looks strong and inflation stays calm, the rebound has a better chance of holding. If either disappoints, the selling could return.
FAQ
What is the Taiex?
The Taiex is Taiwan’s main stock market index. It tracks the largest companies listed on the Taiwan Stock Exchange, and chipmaker TSMC is its biggest member by far.
What is short selling?
Short selling is borrowing shares and selling them, hoping the price falls so you can buy them back cheaper and return them for a profit. It is the opposite of the usual buy low, sell high approach.
Did the stabilization fund buy shares on Monday?
That is not confirmed. The fund was authorized to use its money if needed, but the authorization alone does not prove it bought shares during Monday’s session.
Why did Taiwan’s market fall so much last week?
Investors worried that slower data-center building in the United States after the midterm elections would cut demand for chips. Foreign investors sold heavily, and the Taiex fell 12.19% in the week.
