The narrow gain showed that the market remained divided between renewed buying in selected technology shares and caution toward companies exposed to the sharp rebound in the yen after last week’s coordinated U.S.-Japan currency intervention. Nikkei CNBC’s market framing centered on two forces moving in opposite directions: renewed appetite for AI and semiconductor names, and continued caution over the yen. The yen remained far stronger than July’s low near 163.99, but its slight retreat on August 4 showed that intervention had not eliminated pressure from the U.S.-Japan interest-rate gap. Export-sensitive automakers and electronics companies remained under scrutiny, while some domestic-demand and technology shares recovered. The automaker raised its full-year operating-profit forecast to 3.4 trillion yen after revising its assumed exchange rate to 160 yen per dollar from 150 yen.
