Investing.com-- Asian stock markets rebounded sharply on Tuesday, with South Korea and Japan leading gains amid a rally in AI-related shares, while investors awaited the Reserve Bank of Australia’s policy decision later in the day.
The rebound followed a firm finish on Wall Street overnight, with gains in technology and chipmaking stocks. Investors are awaiting key earnings this week, including from Amazon and Alphabet.
U.S. stock index futures edged higher during Asian hours on Tuesday.
KOSPI jumps 5%, Nikkei climbs 3% on tech rally
Sentiment toward AI-related stocks has been volatile in recent sessions. Optimism around rapid adoption and strong long-term growth prospects had given way to sharp profit-taking after Microsoft's (NASDAQ:MSFT) results highlighted heavy capital spending requirements, raising questions about margins in the near term.
However, Tuesday’s rally suggested investors were willing to look past short-term headwinds, betting that demand for AI infrastructure will continue to support chipmakers and technology suppliers.
Seoul’s KOSPI index surged nearly 5%, with heavyweight chipmakers Samsung Electronics (KS:005930) and SK Hynix (KS:000660) jumping between 6.5% and 8%.
Investors returned to AI-linked stocks on expectations that long-term demand for high-end memory and processors remains intact.
Japan’s Nikkei 225 index climbed more than 3%, buoyed by a broad rally in chipmakers and technology shares, and helped by a weaker yen.
Bucking the regional trend, Hong Kong's Hang Seng index declined over 1%.
In mainland China, the Shanghai Shenzhen CSI 300 index slipped 0.4%, while the Shanghai Composite traded flat.
Elsewhere, Australia's S&P/ASX 200 climbed 1.1%, while Singapore's Straits Times Index added nearly 1%.
US, India sign trade deal; RBA decision on tap
Futures for India's Nifty 50 jumped over 1% before the market opened. U.S. President Donald Trump on Monday announced a trade deal with India, reducing tariffs on Indian goods to 18% from 50%.
The announcement followed months of negotiations during which punitive tariffs had risen as high as 50%, and was widely seen as a step toward normalising trade ties. The deal reportedly entails India phasing out Russian oil purchases and expanding imports of U.S. energy and other goods.
Attention in the region now turns to the Reserve Bank of Australia, which is due to announce its interest rate decision later on Tuesday.
Economists and markets have priced in a 25-basis-point hike to lift the cash rate to around 3.85%, reversing the RBA’s brief easing cycle amid persistently strong inflation data and tighter labour market conditions.
