Asian Stocks Gain as Tech Rally Lifts Wall Street: Nikkei +0.6%, Hang Seng +2.1%

For markets and investment readers, Friday's session is a case study in cross-asset transmission: a 1.4% Nasdaq surge powered by megacap tech and an ebbing 10-year yield to 4.77% flowed straight into Asian benchmarks. The divergence between a 2.1% Hang Seng gain and a flat ASX underlines how oil exposure and tech weighting now shape regional returns.

Asian equity markets were mostly higher in early Friday trading on September 4, 2026, following a tech-led rally on Wall Street that restored some risk appetite after bond-yield pressures eased. Japan's benchmark Nikkei 225 rose 0.6% to 64,622.33, South Korea's Kospi gained 0.9% to 6,635.67, Hong Kong's Hang Seng jumped 2.1% to 25,751.26, and the Shanghai Composite added 0.8% to 3,973.27. Australia's S&P/ASX 200 was an exception, slipping less than 0.1% to 9,011.80. The advance reflected spillover from U.S. markets, where gains were concentrated in communication services and large-cap technology shares.

The session was powered by big technology stocks: Microsoft added 2.7%, Apple gained 1%, Meta climbed 3%, and Nvidia rose 1.8%.

On Thursday, the S&P 500 rose 1.1%, the Dow Jones Industrial Average gained 1.2%, and the Nasdaq composite closed 1.4% higher. The session was powered by big technology stocks: Microsoft added 2.7%, Apple gained 1%, Meta climbed 3%, and Nvidia rose 1.8%. Communication services stocks also contributed heavily to the rally, a reminder that their enormous valuations give them oversized influence over the overall market's direction. Nvidia's move came alongside its statement that it would buy AI platform Hugging Face for $13 billion, reinforcing the sector's conviction that AI infrastructure and tooling remain strategically valuable even at premium prices.

The Asian response was broad but uneven, with Hong Kong's Hang Seng outperforming with a 2.1% surge, while Australia's ASX 200 stayed essentially flat. Japan's Nikkei posted a modest 0.6% gain despite the country's near-total dependence on imported oil, and South Korea's Kospi advanced 0.9%. The uneven moves highlight the dual forces at work: falling U.S. Treasury yields and improving tech sentiment support equities generally, but persistent energy-cost and geopolitical risks impose divergent pressures on oil-importing and commodity-exposed markets.

The 10-year U.S. Treasury yield dropped to 4.77% from 4.79% late Wednesday, having risen steadily throughout 2026 from as low as 4.20% at the beginning of the year. Because this yield influences mortgage rates and broader financing conditions, even a modest decline can improve equity valuations and ease pressure on growth stocks. Investors also focused on recent remarks by Federal Reserve Governor Christopher Waller, with some interpreting his comments as a possible signal on the path of interest rates. The report did not detail the full content of Waller's remarks, but the market's attention to any sign of policy direction underscores how sensitive valuations remain to Fed expectations.
