Today, HESAI-W's stock price plummeted by 9.01%, ranking among the top declines in the Hong Kong stock market, with a trading volume reaching HKD 368 million, indicating a large-scale capital outflow. The MACD daily line formed a death cross signal below the zero axis, suggesting that the medium-term downward trend is being further confirmed, and the bearish forces have shifted from probing to dominating. For a leading lidar company in its growth phase, such a significant single-day decline often indicates a temporary shake in the market's valuation logic, and the bulls will need time to rebuild confidence in the short term. On the industry level, the automotive parts and intelligent driving sectors have recently shown a divergence in performance. BYD's stock fell by 3.94% to HKD 90.2 today, while Geely Automobile dropped by 1.24%, putting pressure on the entire automotive supply chain. On the news front, global long-term bond yields remain high, with the U.S. 30-year Treasury yield reaching 5.20%, a new high since 2007, creating systemic pressure on high-valuation growth stocks in a high-interest-rate environment. Additionally, members of the Federal Reserve's FOMC have clearly stated that interest rate cuts are not advisable until inflation meets targets, further dampening market expectations for liquidity easing. For technology companies like HESAI that are still in the early stages of commercialization and rely on valuation premiums, the deterioration of the interest rate environment directly impacts their pricing foundation. From a technical perspective, the 9% single-day decline has pushed the stock price into the short-term oversold range, but the death cross pattern below the MACD zero axis indicates that the medium-term weakness has not yet bottomed out. The trading volume of HKD 368 million shows concentrated selling pressure, and attention should be paid to whether the volume quickly shrinks—if it stabilizes with reduced volume, a technical rebound may occur; if selling pressure continues to increase, the weakness will further extend. The overall weakness in the Hong Kong stock automotive sector creates a linkage pressure. The short-term trend reference is clearly bearish, and significant volume-driven declines will require time for technical recovery. Under the dual pressure of a global high-interest-rate environment and sector-wide weakness, a rebound may require stronger catalysts to trigger, and investors should be wary of the possibility of trend continuation. _This article provides only technical analysis and market information for reference and does not constitute any investment advice.
