Japan's benchmark Nikkei 225 index tumbled 5.43% on Wednesday, closing at 63,208 points, and Taiwan's stock market shed more than 4% as a wave of profit-taking in semiconductor stocks swept across Asia-Pacific markets.
What Drove the Selloff
A broad retreat from semiconductor shares triggered the region-wide decline. Investors locked in gains after a long rally in chip stocks, which had been fueled by artificial intelligence optimism. The selloff wasn't limited to Japan and Taiwan — markets across the Asia-Pacific region felt the pressure, though the exact percentage declines for other indexes were not specified in the available data.
Nikkei's Sharpest Drop in Months
Wednesday's 5.43% slide is the Nikkei's largest single-day percentage loss in recent months. The index had been hovering near record highs earlier this year, driven by strong exports and a weak yen. Technical factors may have amplified the move: once the selling started, stop-loss orders and momentum traders likely accelerated the decline.
Taiwan's Market Hit Hard
Taiwan's stock exchange, heavily weighted toward semiconductor manufacturers such as TSMC, fell more than 4%. The island's tech-heavy index has been a standout performer in Asia, but the profit-taking suggests some investors believe the sector's valuation has run ahead of fundamentals.
What Investors Are Watching Now
Traders will be watching for any follow-through selling when U.S. markets open, as Wall Street's technology sector has also been sensitive to shifts in sentiment around chip stocks. The broader question is whether this is a one-day correction or the start of a deeper pullback. No major economic data or central bank decisions are scheduled in Japan or Taiwan for the rest of the week, leaving the market to digest the move on its own.
