Japan, South Korea Lead Broad Asia Rally as AI Enthusiasm Returns

Asian stocks rallied on Wednesday, with technology-heavy markets in Japan and South Korea leading the gains, as investors renewed their bets on the artificial intelligence sector. The positive sentiment followed a strong overnight session on Wall Street, where the S&P 500 reached another record high, buoyed by solid corporate earnings, easing oil prices, and lower bond yields.

Wall Street Sets Positive Tone

Investor risk appetite was bolstered by a technology-led rally in the U.S., which saw chipmaker Nvidia rise more than 2%. U.S. stock futures continued to point higher during Asian trading hours, with Nasdaq 100 Futures up around 0.3% and S&P 500 Futures adding 0.1%, according to Investing.com data.

The enthusiasm for AI was not universal, however. Advanced Micro Devices (AMD) shares fell sharply in the U.S. after the company issued weaker-than-expected guidance. Similarly, SpaceX shares declined in extended trading after its first public quarterly report highlighted higher-than-anticipated capital spending on AI infrastructure.

North Asia Tech Leads Regional Gains

Chipmakers and other technology-linked firms across Asia rebounded strongly from a selloff in the prior week. The gains were most pronounced in North Asia, with several key benchmarks posting significant advances.

• Japan: The Nikkei 225 jumped about 3%, while the broader TOPIX index gained nearly the same. Component manufacturers saw strong interest, with Murata Manufacturing surging more than 8% and TDK Corp rising almost 4%.
• South Korea: The KOSPI rallied more than 3%, with major chipmakers leading the charge. SK Hynix gained over 6%, and Samsung Electronics added nearly 4%.
• China and Hong Kong: Chinese equities also advanced, with the Shanghai Shenzhen CSI 300 index rising about 2%. In Hong Kong, the Hang Seng index climbed approximately 1.6%, supported by gains in tech giants like Alibaba and Tencent.

Other Markets and Outlook

Elsewhere in the region, Australia’s S&P/ASX 200 climbed to a new record high, supported by miners and financial stocks. According to IG market analyst Tony Sycamore, the Australian market has benefited from new capital inflows at the start of the financial year and its status as a "lower-beta safe-haven destination."

In contrast, India's Nifty 50 index traded flat as investors awaited a policy decision from the Reserve Bank of India. Looking ahead, market participants are focused on key U.S. economic data, including the ADP private payrolls report and Friday's nonfarm payrolls report, for further clues on the Federal Reserve's monetary policy path.
