The Nikkei 225 rose 0.93 percent to 64,082.36 on Tuesday morning. This gain followed initial losses driven by concerns over artificial intelligence development. Buybacks in major tech firms helped reverse the early weakness.

The Nikkei 225 Stock Average climbed 589.37 points to close the morning session at 64,082.36. This represented a 0.93 percent increase from the previous close. The broader Topix index moved slightly lower, dropping 1.15 points to 4,057.06. The mixed performance reflects a tug-of-war between sector-specific gains and broader market caution.

Sentiment turned negative at the open as investors reacted to statements from U.S. artificial intelligence executives. These leaders suggested a need to slow the pace of technological development. West Texas Intermediate crude oil prices remained above 100 dollars per barrel. High energy costs added to the pressure on equity markets in the early trading hours.

Corporate actions drive recovery

Share buybacks provided a critical support level for the index. SoftBank Group initiated repurchase activities following its previous day decline. This move helped stabilize the technology-heavy Nikkei index. The market appeared to price in the AI development concerns quickly. Subsequent trading saw a rebound in major tech stocks.

The shift in direction indicates that specific corporate actions outweighed macroeconomic fears. Investors focused on tangible value returns from buybacks. This factor supported the broader market rally. The recovery suggests a preference for concrete financial measures over speculative growth narratives.

Currency and Fed speculation

The U.S. dollar strengthened against the yen in Tokyo sessions. The currency pair reached the upper 154 yen range. At noon, the dollar traded at 154.80 to 154.81 yen. This marked an increase from 154.27 to 154.37 yen in the previous New York close.

Market participants bought dollars amid speculation regarding Federal Reserve policy. Traders anticipated potential rate hikes at the upcoming policy meeting. This expectation supported the dollar's strength. The euro remained relatively stable against the dollar at 1.1541 levels.
