Asian Tech Stocks Slide as the AI Selloff Crosses Into the Region

Asia's tech-heavy stock markets fell sharply on Friday, November 6, 2026, as the selloff in artificial-intelligence (AI) shares that hit U.S. markets carried into the region's trading day. Japan's Nikkei 225 Stock Average slid 5.8%, according to Bloomberg, and US News reported the index had fallen more than 6% shortly after the open.
The Nikkei's decline was set to be its largest one-day loss since April 2025. The index was potentially closing in bear market territory, though it had pulled back from its opening lows, per Bloomberg's live coverage. A bear market is conventionally defined as a decline of 20% or more from a recent peak. The MSCI Asia Pacific Index, a broad gauge of stocks across the region, dropped 3.8% on the day.
The damage was steepest in the chip sector. South Korean and Taiwanese stocks plunged more than 8% as chipmakers, which produce the processors that AI systems run on, cratered on AI worries, Reuters reported. MarketWatch described Asian equities as slumping as the selloff deepened, and Yahoo Finance tied the regional move directly to the U.S. rout.
That U.S. rout was the worst since 2020, led by technology stocks, according to Bloomberg's coverage. It followed a broader pattern of pressure on AI trades. On October 22, the Wall Street Journal reported major AI stocks declining as investors questioned the sustainability of debt-fueled AI buildouts, in a session that also produced the Journal's broader tech selloff coverage on AI jitters hitting global markets. In June, the Journal reported that Samsung and SK Hynix each dropped 12% in a rout that began in Asia, with AI and chip companies pushing tech stocks sharply lower.
Reuters reported on October 26 that China's Star 50 index of AI stocks had lost 40% of its value over the prior four months, erasing about $480 billion in shareholder value. The November move therefore landed on markets that were already badly damaged.
The question that matters most here is whether this is a one-session liquidity event or a repricing of AI-linked earnings expectations. In my view, the sequence so far points to the second. Each leg has hit chip names hardest, and the spread from U.S. megacaps to Seoul, Taipei, and Tokyo suggests investors are reassessing AI capital spending rather than reacting to a local shock. The debt angle the Journal flagged in October deserves attention too. When buildouts are financed with borrowed money, falling equity prices tighten the funding conditions for the very companies that are supposed to justify the spending.
For ordinary savers, the practical point is concentration. Index funds covering Asia or global tech carry these weightings whether or not an investor chose them deliberately. A 3.8% regional decline, or an 8% drop in a chip-heavy national index, can move retirement balances and fund statements in ways headline index numbers tend to hide. The losses have now crossed from Wall Street into Asia, and the markets absorbing them had already fallen hard over the preceding months.
