Asian Stocks Surge as Hong Kong Rallies on AI Hype and China Stimulus

Asian stocks climbed on Tuesday, with Hong Kong leading gains as optimism over China’s economic stimulus and growing confidence in AI innovation fueled a rally in major tech stocks.

Hong Kong’s Hang Seng Index jumped nearly 2% to a three-year high, driven by a 10% surge in Baidu (NASDAQ:BIDU) after launching two new AI models. Alibaba (NYSE:BABA) gained over 4% following reports that its 2025 performance metrics will focus on AI-driven growth. BYD Co (HK:1211) also hit a record high after unveiling fast-charging EV technology.

China’s broader markets advanced, with the Shanghai Shenzhen CSI 300 and Shanghai Composite adding 0.3% and 0.2%, respectively. Investors welcomed Beijing’s stimulus plans, boosting confidence in a 2025 economic recovery.

Japanese stocks outperformed, with the Nikkei 225 up 1.6% and the TOPIX rising 1.5%. Warren Buffett’s Berkshire Hathaway increased its holdings in Japan’s five largest trading houses—Itochu Corp. (TYO:8001), Mitsui & Co. (TYO:8031), Mitsubishi Corp. (TYO:8058), Sumitomo Corp. (TYO:8053), and Marubeni Corp. (TYO:8002)—to nearly 10%, fueling strong gains.

Markets also focused on the Bank of Japan’s upcoming meeting, where the central bank is expected to hold rates but adopt a hawkish tone amid signs of economic resilience.

Elsewhere, Australia’s ASX 200 rose 0.2%, South Korea’s KOSPI gained 0.3%, and Singapore’s Straits Times Index surged 0.9%. India’s Nifty 50 futures pointed to a positive open, tracking regional momentum.

Despite strong stock market gains, U.S. stock index futures dipped in Asian trading as investors remained cautious over trade tariffs, a potential recession, and an upcoming Federal Reserve meeting. Meanwhile, heightened geopolitical tensions in the Middle East dampened risk appetite.
