On July 9th, the three major A-share indices opened high in the morning and then fell. The ChiNext Index rose by more than 1.8% at one point, but then fluctuated and fell back. By the midday close, the Shanghai Composite Index fell by 0.46%, the Shenzhen Component Index fell by 0.35%, the ChiNext Index rose by 0.13%, and the Kechuang 50 Index rose by 3.19%. Most individual stocks in the two markets fell more than they rose, with over 4600 individual stocks falling. The two markets had a total turnover of 1.7 trillion yuan in the morning session, a decrease of 54 billion yuan compared to the previous day. In terms of market performance, the semiconductor sector was active, with a collective strength in the Longxin concept, storage chips, advanced packaging, semiconductor materials and equipment. Muxi shares rose by over 19%, reaching 1000 yuan per share to achieve a historical high. The PCB concept also showed strength, with Baoding Technology hitting the limit up, and other stocks following suit. The innovative pharmaceutical concept saw a rebound during the day, with companies like Chengdu Xiandao and Asymchem Laboratories experiencing significant gains. The oil and gas sector continued its strength, with Tong Petrotech Corp. rising by over 17%. On the downside, the non-ferrous metal sector saw a decline, with Xinjiang Baodi Mining leading the way. The lithium battery industry chain continued to decline, with companies like Guangzhou Tinci Materials Technology and Delixi New Energy Technology hitting the limit down. Energy metals and lithium resource stocks also weakened. In terms of automation, Siasun Robot & Automation showed weak performance. Additionally, the ultra-high voltage and power grid equipment sectors performed poorly, and the chemical stocks continued to adjust. In terms of news, on July 9th, Longxin Technology, a leading domestic DRAM company, released its IPO prospectus and preliminary pricing announcement for the Kechuang board, with the company's new shares expected to be available for purchase on July 16, 2026. Public information shows that Longxin Technology is the largest and most technologically advanced integrated DRAM research, design, and manufacturing company in China. Since its establishment in 2016, the company has focused on the research, design, production, and sales of DRAM products. The company has completed the production from the first-generation technology platform to the fourth-generation technology platform, and its core products and technology have reached international advanced levels. Guolian Minsheng Securities pointed out that under the demand for AI, global semiconductor industry prosperity continues to rise, and the storage industry chain inflation and production expansion resonate. Longxin Technology's IPO may drive a new Capex cycle in China. Looking ahead, EB SECURITIES believes that the A-share market sentiment remains cautious. Stock market speculation is evident, which continues to restrict short-term market trends. Looking ahead, with the centralized disclosure of interim performance forecasts, the logic of "performance determines success or failure" becomes increasingly clear. Popular sectors mentioned in the report include the strength of the computing power chip concept, the oscillation strength of the PCB concept, the rebound of the innovative pharmaceutical concept, and the continued strength of the oil and gas concept. In terms of institutional views, EB SECURITIES believes that the current stock market shows a speculative nature that continues to restrain short-term market trends. Orient Securities believes that the short-term market is in a downward trend and recommends a balanced approach to investing.
