Alibaba Group Holding Ltd.'s shares surged 19% in Hong Kong trading on Monday, marking the company's biggest single-day gain in over two years and reflecting renewed investor optimism in its artificial intelligence-driven growth strategy. The rally was fueled by robust quarterly results from Alibaba's cloud computing division, which reported an 11% year-over-year revenue increase, largely attributed to surging demand for AI-related services. This performance comes amid broader challenges for the Chinese tech giant, including regulatory scrutiny and a sluggish domestic economy, yet it underscores a pivotal shift toward high-margin tech segments.
