Japan's Nikkei 225 faced a sharp sell-off on Thursday, closing nearly 3% lower as semiconductor stocks corrected and geopolitical tensions spooked investors. Even TSMC’s stellar earnings couldn’t stop the market retreat.

Semiconductor Correction Overshadows TSMC’s Massive Growth

TSMC posted a record-breaking 77% jump in net profit, driven by fierce demand for AI processors, and nudged its full-year revenue growth forecast to just above 40% in U.S. dollars. Yet the Nikkei ignored that strength. Memory-chipmaker Kioxia plunged 15%, SoftBank Group’s tech arm slid 6.3%, and chip-tester Advantest shed 5.9%. Analysts say leveraged ETFs and high-margin buying, not company fundamentals, sparked the sell-off.

Geopolitical Tensions and Middle East Conflict

The tech slump spread as Middle-East conflict heated up. After two U.S. strikes on Iran’s coastal defenses, Iran retaliated against U.S. sites in neighboring countries, draining risk appetite worldwide.

The Nikkei ended at 66,835.54, down 2.8%, while the Topix fell 1.5% to 4,028.79. Market breadth stayed negative—139 decliners versus 85 advancers. Oil prices wavered as traders weighed the threat of broader clashes.

Sector Divergence: Winners and Losers

Some stocks bucked the trend. Nichirei surged up to 7.7% after announcing the restart of frozen-food shipments and refrigerated warehouse operations that had been halted by a cyberattack.

The episode underscores a volatile correction in high-tech stocks, even as AI-driven chip demand hits record highs.

Key Takeaways

  • Tech Disconnect: TSMC’s 77% profit jump and higher revenue outlook couldn’t lift Japanese chip names—Kioxia fell 15% and Advantest dropped 5.9%.
  • Geopolitical Pressure: Rising U.S.–Iran hostilities spooked markets, helping push the Nikkei down 2.8%.
  • Market Mechanics: Analysts point to supply-demand factors—leveraged ETFs and margin buying—as the main drivers of the tech-stock tumble, not weak fundamentals.

Japan’s Nikkei 225 slipped 2.8% on Thursday, pulled lower by a steep sell-off in semiconductor-related shares even though Taiwan’s TSMC posted a record-breaking 77 % jump in net profit. The divergence shows that soaring AI-driven chip demand isn’t enough to buoy a market rattled by geopolitical risk and a technical correction in Japan’s high-tech sector.

The chip rally that didn’t lift the index

TSMC’s second-quarter results made headlines: net profit surged 77% and the company nudged its full-year revenue outlook to just over 40% growth in U.S. dollars. Those numbers reflect the global scramble for AI processors, a trend powering chip makers everywhere.

Yet Japanese semiconductor names moved the opposite way. Memory-chip leader Kioxia tumbled 15%, testing-equipment specialist Advantest shed 5.9%, and SoftBank Group’s tech arm fell 6.3%. Analysts point to supply-demand mechanics rather than company fundamentals as the primary driver. Heavy buying on leveraged ETFs that bet on a continued rally forced many investors onto margin—borrowing to amplify exposure. When the market turned, those leveraged positions were unwound quickly, amplifying the drop.

In short, the correction was a market-structure event. Even a stellar earnings surprise from the world’s biggest foundry could not overcome the pressure from short-term trading dynamics.

Geopolitical tension adds a risk-off flavor

The chip sell-off was compounded by a flare-up in the Middle East. The United States launched two strikes against Iran’s coastal defenses, and Iran responded with attacks on U.S. military sites in neighboring states. The escalation sent risk appetite tumbling across global markets, prompting investors to shift into cash and defensive assets.

Oil prices wavered as traders priced the possibility of a broader conflict, reinforcing the cautious tone. With the geopolitical backdrop turning sour, even sectors with strong earnings momentum struggled to find buyers.

Market breadth and the broader index

The Nikkei closed at 66,835.54, down 2.8%, while the Topix slipped 1.5% to 4,028.79. Breadth was decidedly negative: 139 stocks fell versus 85 that rose. The imbalance shows the sell-off spread across the market, reflecting heightened nervousness among investors.
