Nikkei Recovers 69,000 as AI Shares Defy Weak GDP

The Nikkei 225 stock index climbed to 69,220.25 points on August 17, up 506.45 points, as artificial intelligence and semiconductor-related shares outperformed weaker-than-expected economic growth, rising bond yields, and renewed concern over household spending. The index had not been this high in about a month and a half.

The rally was largely driven by a small group of high-impact technology shares, with Prime Market trading volume totaling around 2.09249 billion shares. However, the broader market was less strong, with only about 40% of stocks advancing while roughly 57% declined.

Artificial intelligence and semiconductor-linked heavyweights lifted the Nikkei, while many domestic-demand and selective sectors, including pharmaceuticals, wholesale, and consumer-related shares, fell. Nikkei commentary focused on the continued strength of the AI trade, despite weaker U.S. consumer indicators and a softer Wall Street session before the weekend.

Advantest and Kioxia Holdings were the top contributors to the Nikkei's recovery, each adding approximately 219 and 190 points, respectively. Advantest's rise was driven by continued demand expectations for AI processors and high-performance computing, while Kioxia's rebound helped restore confidence in Japan's semiconductor complex.

SoftBank Group also contributed to the index's gains, rising 147 points. Tokyo Electron, Fujikura, and Ibiden also saw notable increases, indicating that the AI trade had expanded beyond chipmakers and equipment manufacturers into related infrastructure and supply chains.

However, the broader market was less strong, with the majority of stocks declining. This disparity highlighted investors' concentration on companies with direct exposure to AI investment, despite concerns about valuations following the July correction and weak domestic demand.
