What caused the market sentiment to fluctuate? **U.S. Stock Night Market Movements** Yunji fell 17.61% in the night market, with no significant news recently. Trading is active, and capital flows are evident. Considering the sector and industry trends, the stock shows significant volatility, and the specific reasons need further observation. **Stocks with High Trading Volume in the Industry** Alibaba fell 0.87% in the night market. Based on recent key news: 1. On February 3, market rumors suggested that the Chinese government might raise the value-added tax for the gaming and financial industries, raising investor concerns about the profit margins of internet giants, leading to a drop in Alibaba's stock price. According to Bloomberg, the Hang Seng Tech Index briefly approached bear market territory. 2. On February 2, Alibaba announced that its Qianwen APP would invest 3 billion RMB to launch Spring Festival activities. Although this move aims to promote AI applications, market concerns about price wars among tech giants intensified, affecting stock performance. 3. On February 4, the Hong Kong stock market experienced increased volatility, with tech stocks plummeting due to tax rumors. Alibaba's stock opened down 1.0% at 159.4 HKD. According to Xinhua News Agency, the rumors lack authenticity, but market sentiment is still affected. Valuation concerns in tech stocks have intensified market volatility. Amazon rose 0.11% in the night market. Based on recent key news: 1. On February 1, Amazon planned to lay off thousands of employees to streamline its organizational structure and accelerate AI integration. This move attracted market attention and could impact AWS, Prime Video, and retail sectors, leading to stock price fluctuations. 2. On February 2, Amazon announced that its capital expenditures for fiscal year 2026 would exceed 150 billion USD, with increased AWS capacity helping to meet AI infrastructure demands, driving stock price up. 3. On February 3, Amazon's stock price rose 2.1% after the company announced it would cut about 16,000 jobs while continuing to hire in strategic areas, boosting market confidence. The investment boom in the AI industry continues, with attention on valuation risks. JD.com fell 0.93% in the night market. Based on recent news: 1. On February 3, JD.com's stock showed weak fluctuations, with three consecutive bearish candles on the daily K-line, and continuous volume contraction during the session, gradually approaching a previous important support area. Due to industry profit pressures and weaker-than-expected consumer recovery, JD.com's short-term fundamentals lack significant catalysts, leading to a stock price decline. Source: Zhitong Finance 2. On February 2, JD.com signed a strategic cooperation agreement with the China-Britain Business Council to promote local business development in the UK. Although this move helps long-term growth, it failed to significantly boost the stock price in the short term. Source: Zhitong Finance 3. On February 3, JD.com will invest over 1.3 billion RMB during the Spring Festival to provide welfare subsidies for frontline employees. Although this move shows the company's emphasis on its employees, it did not have a positive impact on the stock price. Source: Zhitong Finance.
