Over the past week, China's three major A-share indices were mixed. Landun Optoelectronics became the strongest stock with a weekly gain of 148.76%, while Gansu Consulting led declines with a weekly drop of 24.82%. On August 14, Landun Optoelectronics sealed another 20% limit-up, securing its fifth consecutive daily limit since resuming trading, with the share price at 47.29 yuan and a total market value of about 8.7 billion yuan. Its cumulative gain over the past five trading days reached nearly 150%. The core catalyst for this surge was the major asset restructuring plan disclosed on the evening of August 7, under which the company intends to acquire a controlling stake in Suzhou Lanchuang Technology through a combination of share issuance and cash payment. The target company mainly produces high-performance vacuum coating equipment, which is manufacturing equipment for the company's upstream core optical components. Landun Optoelectronics said the transaction is a key step in improving its optoelectronics industry chain layout. After completion, it will add a high-performance vacuum coating equipment business, achieving a strategic extension from high-end optical analysis and measurement instrument manufacturing to upstream core optical thin-film equipment manufacturing. The company also cautioned that the transaction may be suspended, terminated, or cancelled, and that its overall operating performance still faces significant challenges. Full-year 2025 revenue was 399 million yuan, down 34.53% year on year, with a net loss attributable to shareholders of the listed company of 88.77 million yuan. The weakest stock, Gansu Consulting, hit a high of 14.67 yuan on August 6, its highest since May 2022, before reversing sharply. It fell by the daily limit on August 7, August 10, August 13, and August 14. As of the close on August 14, it reported 9.66 yuan, with a total market value of about 4.49 billion yuan, despite first-quarter 2026 net profit attributable to the parent company of 58.25 million yuan, up 5.90% year on year.
