Cambricon(SH:688256) Qi Lu Wan Bao Wang·2025-09-04 08:52Market Overview - The A-share market experienced a significant adjustment on September 4, with all three major indices closing lower. The Shanghai Composite Index closed at 3765.88 points, down 1.25%, the Shenzhen Component Index at 12118.70 points, down 2.83%, and the ChiNext Index at 2776.25 points, down 4.25%. The STAR Market 50 Index fell by 6.09% to a lower level [1] - The total trading volume in the Shanghai, Shenzhen, and Beijing markets reached 25,819 billion yuan, an increase of 1,862 billion yuan compared to the previous trading day [1] Sector Performance - The market displayed a "dual performance" with the consumer sector showing resilience. Retail stocks led the gains, with companies like Huijia Times, Guofang Group, and Baida Group hitting the daily limit. The tourism and food & beverage sectors were also active, driven by the launch of new consumption vouchers in multiple regions [2] - The new energy sector also performed well, with solar energy stocks like An Cai Gao Ke hitting the daily limit, and energy storage and solid-state battery stocks showing strong activity. The domestic new energy storage installed capacity exceeded 100 GW in the first half of the year, providing momentum for the sector [4] Notable Stock Movements - Cambrian, known as the "first domestic AI chip stock," saw a sharp decline of 14.45%, with its market value evaporating by nearly 84 billion yuan in a single day. The stock closed at 1202 yuan per share after a drop of 15.85% during the day. The adjustment is closely related to the upcoming changes in the STAR Market 50 Index sample, which will reduce Cambrian's weight from 15% to 10% [5][6] - Despite Cambrian's significant revenue growth of 4,347.82% year-on-year to 2.881 billion yuan and a net profit of 1.038 billion yuan, its price-to-earnings ratio remains extremely high at 5,117 times, raising concerns about its valuation deviating from fundamentals [5] Market Sentiment - The overall market showed a clear trend of high-low switching, with previously high-performing sectors like AI computing and semiconductors experiencing collective pullbacks. In contrast, lower-performing sectors such as consumer goods, new energy, and some financial stocks attracted capital inflows [7] - Despite the strong performance in the new energy sector, it was not enough to reverse the overall market decline, with over 2,990 stocks falling and only 2,297 rising, resulting in a significant number of stocks hitting the daily limit down [7]
