As of the close, the Hang Seng Index rose 1.46% to 23,294.42, the Hang Seng Tech Index rose 0.29%, and the China Enterprises Index rose 1.37%. On the board, internet stocks were mostly higher, with Meituan and Xiaomi up more than 3%, while Lenovo fell more than 7%; oil stocks strengthened, with PetroChina up more than 5%; food stocks advanced, with Tingyi up more than 5%; the application software sector was sluggish, with Zhipu down more than 9%. Oil stocks strengthened, with PetroChina up more than 5%. PetroChina recently released its 2026 third-quarter report. In the third quarter, operating revenue was 793.573 billion yuan, up 10.4% year on year; net profit attributable to shareholders was 51.84 billion yuan, up 21.6% year on year. Everbright Securities said that in the first three quarters, PetroChina's full-industry-chain advantages were highlighted, and its performance reached a new high, in line with expectations. It is bullish on the company's potential for "increasing reserves and production" and the long-term growth of its natural gas business, maintaining a "buy" rating on the company's A+H shares. Food stocks advanced, with Tingyi up more than 5%. Kaisheng Securities pointed out that the sector's chip structure is showing a trend of improvement. Along with long-term adjustment, pressure from institutional holdings and floating shares has been released to some extent, and the PE of most leading companies is at a historically low percentile, while market expectations have already been revised downward. Overall, the combination of low valuation, low expectations, and low crowding constitutes an objective basis for left-side allocation in the sector. Analysts said that the core support for the food and beverage sector's recent strength against the trend comes from a "rebalancing" on the funding side. The application software sector was sluggish, with Zhipu down more than 9%. Overnight, Google's stock price closed down 12.64%, the largest single-day drop since its listing in 2004. Its market value evaporated by nearly $500 billion in a single day, the second-largest single-day market value loss in U.S. stock history, second only to Nvidia's record in January 2025. The company's third-quarter revenue and adjusted earnings per share both missed expectations, and free cash flow turned negative to $9.07 billion. Google's financial report made the market question both the monetization capability of the AI application side and the pace of capital expenditure growth on the AI hardware side.
