Asian stocks rise on AI rally; US futures edge higher

Asian stocks mostly rose Tuesday following an AI-led rally on Wall Street, with U.S. futures edging higher and oil prices extending losses ahead of major corporate earnings and central-bank decisions. South Korea's Kospi jumped 3.6%, led by chipmakers SK Hynix and Samsung Electronics, while Tokyo's Nikkei 225 added 2.2% on gains in AI-related stocks like Advantest and SoftBank Group. Hong Kong's Hang Seng slipped 0.2% and Shanghai's Composite edged 0.1% lower, with traders watching China's closed-door Communist Party plenum. On Monday, the S&P 500 rose 0.7%, recovering losses from last week, driven by Nvidia's 2.4% gain. Alphabet, Microsoft, and Amazon report earnings this week, offering insight into AI spending, while the Federal Reserve is expected to hold rates steady Wednesday.
