Japan's Nikkei index traded unevenly on Wednesday as investors waited for major U.S. technology earnings. AI- and chip-related shares remained under pressure, extending a global weakness in the sector. The setup kept attention on a handful of large-cap technology results abroad, since those reports can influence sentiment across semiconductor and hardware names that are closely tied to the AI trade.
Geopolitical tensions in the Middle East also weighed on sentiment and added to uncertainty in the market. The tensions contributed to higher oil prices, which further shaped trading conditions. For Japanese equities, that combination can make a broad market rally harder to sustain, especially when energy-sensitive pricing and risk appetite are moving at the same time.
Even so, the broader market found some support from strong earnings at select companies, including Keyence. Market breadth remained positive despite the Nikkei's subdued performance, highlighting that weakness in AI-linked stocks did not fully overwhelm the wider exchange.
Artificial intelligence-related shares continued to lead the decline on Wednesday.
