- After a dramatic sell-off in global tech stocks, Asian markets struggled to rebound on Wednesday. The MSCI Asia Pacific Index, which initially rose nearly 1%, turned down by 0.9% as the tech sector faced another wave of selling pressure, indicating ongoing concerns about overvaluation in the AI industry.
- As a bellwether for the regional semiconductor industry, chip giant TSMC (TSMC:US/2330:TW), which accounts for over 10% of the MSCI Asia Pacific Index, saw its stock price decline, directly dragging down Taiwan's weighted index. In contrast, South Korea's Kospi index found some support after erasing early losses, amid market rumors that Samsung Electronics (005930:KS) might announce a 90 trillion won stock buyback plan for bonuses.
- The dollar index climbed to a seven-month high driven by safe-haven flows, while Brent crude futures fell about 1% to near $76 a barrel, mainly due to a temporary peace agreement between the US and Iran, reducing shipping risks in the Strait of Hormuz.
Tech Sector Faces Valuation Correction
In this market volatility, investor optimism towards the semiconductor and AI sectors has reversed. The Asian benchmark index fell 3.6% in the previous session, marking the largest single-day drop since early March, with South Korea's Kospi index plunging 10%. This sell-off then spread to the US stock market, causing the Nasdaq 100 index to drop 3.3% and the S&P 500 index to fall 1.4%, while a closely watched semiconductor index also fell about 8%. Previously high expectations for capital expenditure returns from tech companies, along with high valuations and crowded positions, made any negative marginal changes likely to trigger rapid restructuring of leveraged positions.
Market Focus on Micron Earnings and Supply-Side Variables
Against this backdrop, the upcoming financial report from memory chip maker Micron Technology (MU:US) has become a key driver for assessing the resilience of AI infrastructure demand. Micron's stock fell 13% in the previous session, although its cumulative gain since 2026 still exceeds 250%. Additionally, newly listed chip company Cerebras Systems fell about 11% in after-hours trading, as its annual sales forecast fell short of market expectations, further intensifying investor concerns about whether AI-driven growth is too fast and too large.
Capital Outflows and Regional Index Status Adjustments
Beyond tech stock movements, regional market policy changes also have a substantial impact on capital flows. Indonesia's stock market fell about 1.5%, mainly due to MSCI's further delay in assessing the country's stock market, stating that more time is needed to observe the effectiveness of recently announced transparency reforms. MSCI had previously warned that due to concerns about investability, Indonesia's stock market might be downgraded to frontier market status. Meanwhile, MSCI has retained South Korea in its emerging market index basket, not upgrading it to developed market status.
Safe-Haven Sentiment Drives Divergence in Forex and Bond Markets
The currency and fixed income markets have fully reflected the defensive shift in asset allocation. The Bloomberg Dollar Spot Index recorded its third consecutive day of gains, while spot gold was under pressure for the second consecutive day as investors needed to cut positions to offset losses in other assets. In the US bond market, stock market adjustments and falling oil prices have somewhat eased inflationary pressures, stabilizing US bond yields. The market's current trading focus has shifted to the upcoming personal spending data, seeking more clues on the Federal Reserve's subsequent monetary policy path.
