SiTime nears $3 bln deal to buy Renesas timing unit, Bloomberg reports

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.

Investing.com-- Tesla Inc (NASDAQ:TSLA) introduced a new all-wheel drive variant for its Model Y sports utility vehicle, the electric vehicle maker’s website showed on Monday evening. 

Tesla’s website showed the company selling a new, all-wheel variant of the Model Y for $41,990, checks by Investing.com showed. A premium version of the model is available for $48,990. 

The premium model features upgraded interiors and suspension, front and rear lightbars, and slightly better claimed range and performance over the regular Model Y, Tesla’s website showed. 

The Model Y is Tesla’s best-selling car, and is also one of the best-selling EVs in the world.

But sales of the model, along with Tesla’s other vehicles, were seen falling off in the past two years, amid a mix of stiff competition and souring consumer sentiment towards Tesla over CEO Elon Musk’s political affiliations. 

Tesla had in 2025 introduced cheaper, stripped down versions of the Model Y, although this was seen doing little to lift sales. 

Musk recently said Tesla will stop production of its S and X models, as it shifts towards robotics.
