Nikkei Hits Record High as AI Rally Surges on Micron’s Strong Forecast

Japan's equity markets witnessed a historic milestone on Thursday as the Nikkei 225 surged to a record closing high. This massive rally was fueled by a wave of optimism in the artificial intelligence sector following a highly positive quarterly outlook from U.S. memory chip giant Micron.

Micron’s Stellar Forecast Triggers Semiconductor Surge

The primary catalyst for the market's upward trajectory was the upbeat guidance provided by Micron Technology. As a critical supplier for Nvidia's AI processors, Micron's financial outlook sent shockwaves through the semiconductor supply chain. The company forecast quarterly profit and revenue figures that significantly exceeded market expectations.

Crucially, Micron revealed that customers have already committed $22 billion to secure its memory chip supply, signaling robust, long-term demand for AI-related hardware. This news directly benefited Japanese semiconductor-related stocks, which share a high correlation with U.S. semiconductor indices. Key beneficiaries included chip-testing equipment maker Advantest, which jumped 15%, and Tokyo Electron, which rose 7.78%. Additionally, memory chipmaker Kioxia saw a substantial gain of 12.27%.

SoftBank and AI Infrastructure Stocks Lead the Charge

The rally extended beyond pure semiconductor manufacturers into the broader technology and AI infrastructure sectors. SoftBank Group, a major player in the global tech landscape, reversed its recent downward trend to jump 8%. Analysts noted that while investors had previously engaged in profit-taking ahead of the Micron earnings, the strong results prompted a massive re-entry into tech shares.

The momentum was also visible in companies providing essential materials for AI data centers. Murata Manufacturing climbed 7.21%, while Taiyo Yuden rose 11.2%. This broad-based movement across the technology ecosystem contributed to the Nikkei closing 4.6% higher at 72,366.34, effectively snapping two consecutive sessions of declines.

Energy and Shipping Sectors Defy the Market Trend

While the technology sector drove the Nikkei to new heights, the broader market showed signs of divergence. The energy sector faced significant headwinds as falling global oil prices weighed on domestic stocks. The mining sector dropped by 3.18%, with Inpex falling 3.35%, and oil refiners saw a decline of 1.38%.

The shipping industry also struggled to keep pace with the tech rally. Japanese shippers slipped 2%, with Kawasaki Kisen recording a 3.87% drop. Despite these sectoral laggards, the sentiment on the Tokyo Stock Exchange remained largely positive, with 66% of the 1,500 stocks on the prime market ending the session in the green.

Key Takeaways

  • AI Demand is Tangible: Micron’s $22 billion in customer commitments underscores the massive, concrete demand for memory chips required to power the global AI revolution.
  • Semiconductor Correlation: The Nikkei’s performance is increasingly tied to U.S. semiconductor trends, with Japanese equipment makers like Advantest and Tokyo Electron reacting sharply to global chipmaker news.
  • Sectoral Divergence: While the AI-driven tech rally pushed indices to record highs, commodity-linked sectors like energy and shipping faced selling pressure due to falling oil prices.
