Investing.com– Most Asian stocks rose on Tuesday, with Hong Kong markets rallying on increasing optimism over more Chinese stimulus, while confidence in the country’s AI capabilities drove buying into major technology shares.
Japanese shares were also standout performers, with the country’s five largest trading houses marking strong gains after billionaire investor Warren Buffett’s Berkshire Hathaway Inc (NYSE:BRKa) increased its holdings in the companies.

(TYO:8053), and Marubeni Corp. (TYO:8002)- after Berkshire Hathaway increased its holdings in each company to nearly 10%.
