Do you expect the stock market to recover from this AI-driven selloff?
Fears about tighter AI regulations in the United States wiped trillions of dollars off world stock markets. Japan's Nikkei and South Korea's KOSPI slumped about 6 per cent, while Taiwan's benchmark plunged more than 8 per cent at one point before cutting losses.
Why it matters
The sell-off shows how heavily global markets now depend on artificial intelligence stocks, which fell sharply as investors weighed the prospect of stricter rules. Investors moved into safe-haven government bonds during the decline, a sign of growing caution across markets.
Japan's Nikkei and South Korea's KOSPI each slumped about 6 per cent, with the Nikkei's drop its biggest one-day decline since April 2025. Nvidia suffered its worst day since January 2025, and it is not yet known how long the selling will last.
The players
Nvidia
Nvidia is a leading designer of graphics processors and AI chips whose stock is closely watched as a barometer of investor enthusiasm for artificial intelligence.
Tesla
Tesla is an electric vehicle and energy company led by Elon Musk, whose shares are widely followed by retail and institutional investors.
The details
Retail and hedge fund selling fed off each other, pushing Europe's main bourses down over 1.5 per cent while Nasdaq futures pointed 1.5 per cent higher before the open. Authorities in Taiwan scrambled to stem the selling, and chipmakers including AMD, Intel, Broadcom and Micron Technology rose between 4.5 and 8 per cent in premarket trading.
Timeline
April 2025: Trump's Liberation Day trade tariff panic hit markets.
January 2025: DeepSeek's low-cost AI model hammered markets.
November 5, 2026: Fears about US AI regulation triggered the sell-off.
Market Dynamics
The sell-off follows the pattern set in January 2025, when the DeepSeek low-cost AI model hammered markets. Like that episode, it shows how quickly news about artificial intelligence can reshape global equity prices.
Investors with exposure to technology and AI shares may see their portfolios swing sharply in the coming days. The sell-off also highlights how a shift toward government bonds can affect asset allocation decisions.
The takeaway
Concentrated bets on a single technology theme can leave portfolios exposed to sudden shifts in policy expectations. Investors should review how much of their holdings depend on AI-linked stocks.
