U.S. technology stocks bounced back at the start of the new session, with the Nasdaq Composite climbing by more than 1%. The move came after a sell-off the week before, and it was led by gains in Tesla, Nvidia and Alphabet, three of the market's most closely followed large-cap names.

The recovery in New York did not carry over to Asia. Equities across the region slumped, with worries about artificial intelligence weighing heavily on South Korean semiconductor manufacturers. Coverage of the session described the pressure on chipmakers as coming ahead of a run of technology earnings, suggesting that investors in the region were reluctant to follow the Wall Street rebound before fresh company results arrived.

The split between the two markets reflects an uneven mood toward the AI trade. In the U.S., some investors appeared willing to buy shares after the recent decline, a pattern market commentary often labels dip-buying. In Asia, by contrast, the same enthusiasm was not evident, and chip-related shares in Korea took the brunt of the selling.

Debt emerged as a separate and persistent source of unease. Even as the Nasdaq rallied, some companies remained out of favor with investors. Coreweave was cited as one such name that buyers were still avoiding. Bonds issued by Oracle were also reported to be approaching the threshold of junk status, a reference to the border between investment-grade and high-yield credit ratings. The sources do not provide further details on pricing, yields or ratings actions, so the extent of that pressure is not quantified here.

Taken together, the reports describe a market in which equity sentiment toward big technology names can improve quickly, while questions about financing for AI-related spending continue to sit in the background. The upcoming technology earnings season was flagged as the next point of focus for investors in Asia, where chipmakers have been among the most sensitive to shifts in AI sentiment.
