Nasdaq futures edged higher in overnight trading Thursday after Wall Street staged a sharp rebound. Upbeat earnings from Amazon added to optimism.

Nasdaq 100 futures gained 0.5%. Futures on the Dow Jones Industrial Average rose 0.2%, while S&P 500 futures inched up 0.1%

In Asia, Japan's benchmark Nikkei 225 was set to jump, with the futures contract in Chicago at 63,830 against the index's last close of 61,867.43. Futures for Hong Kong's Hang Seng index last traded at 26,021 compared to the index's last close of 25,858.88. Futures for Australia's benchmark S&P/ASX 200 were last at 9,010 compared to the index's last close of 8,967.7.

In extended trading, Amazon surged more than 9% after reporting better-than-expected second-quarter revenue. The results, which were aided by the strength of its cloud-computing business, reinforced investor confidence in artificial intelligence spending.

Apple's fiscal third-quarter revenue topped expectations, helped by a 22% jump in iPhone sales. However, a shortfall in service revenue led to a 6% decline in its stock.

The after-hours moves followed a powerful rally during Thursday's regular session, led by Microsoft, which jumped 16% after the software giant posted stronger-than-expected Azure cloud growth. The results sparked a broad advance across AI-linked chipmakers, with the iShares Semiconductor ETF (SOXX) climbing more than 8%.

The recovery came after a bruising session on Wednesday, when the Dow plunged more than 1,100 points, its worst one-day decline since April 2025. Selling accelerated late in the session after the Federal Reserve held interest rates steady, fueling concerns that policymakers were falling behind in the fight against inflation.

Those worries rippled through the Treasury market. The 30-year Treasury yield climbed 6 basis points Wednesday to above 5.2%, hovering near its highest level since 2007.

"Investors are recalibrating expectations for Fed rate cuts, reducing the excess liquidity that has fueled speculative, momentum-driven markets," Richard Bernstein, global head of macro and customized investing at Janus Henderson Investors, said. "Market leadership is expanding beyond the 'Magnificent 7' as investors increasingly reward improving fundamentals rather than hype-driven momentum."

Despite the week's sharp swings, the major averages remained on track to finish higher. The Dow was up about 0.5% for the week heading into Friday's session, while the S&P 500 had gained roughly 0.4% and the Nasdaq Composite was ahead about 0.6%.
