CICC released a research report on September 16 stating that "locking orders" and "locking materials" became key words in exhibition surveys, with order schedules for some high-speed optical chip companies extending to 2028 and beyond, and visibility for optical module orders covering 2027 and beyond; a Goldman Sachs report released on September 7 raised its forecast for the global optical module market space from 2026 to 2028. On the policy front, the Ministry of Industry and Information Technology and five other departments jointly issued the "Opinions on Promoting the High-Quality Development of Historical Classic Industries" on September 7, incorporating traditional specialty industries such as brewing into the support framework. The yellow rice wine concept rose 7.65% on the day, ranking first among concept sector gainers. On the day, the combined turnover of the Shanghai and Shenzhen markets increased by 226.405 billion yuan from the previous trading day, but sectors such as banking, insurance, complete automobiles, and construction machinery closed lower. Hot sectors 1. Semiconductors: The semiconductor industry chain strengthened across the board, with silicon wafers, silicon carbide, and equipment leading the gains. GRINM Semiconductor Materials hit the 20CM daily limit up, Crystal Growth & Energy Equipment Inc. hit the 20CM daily limit up, Grinm Advanced Materials, Hangzhou Lion Microelectronics, and Zhejiang MTCN Technology hit the daily limit up, and SICC Co.,Ltd. rose more than 11%. A CITIC SEC research report expected that the relatively tight heavily doped silicon wafers are likely to continue rising in price in the second half of the year, and related companies may raise next year's long-term agreement prices in September to October. 2. Computing power hardware: CPO, optical communications, and optical fiber directions collectively surged. Shenzhen Zesum Technology and Jiangxi Welgao Electronics hit the 20CM daily limit up, Accelink Technologies, Jiangsu Etern, Nanjing Huamai Technology, and Fujian Qingshan Paper Industry hit the daily limit up, Hubei DOTI Micro Technology rose more than 14%, and EverProX Technologies rose more than 12%. After surveying the 27th China International Optoelectronic Exposition, CICC noted that order schedules for some high-speed optical chip companies have extended to 2028 and beyond, and visibility for optical module orders covers 2027 and beyond. 3. Yellow rice wine: The yellow rice wine concept index rose 7.65%, ranking first among concept sector gainers on the day. Kuaijishan Shaoxing Rice Wine recorded a second consecutive daily limit up, while Zhejiang Guyuelongshan Shaoxing Wine and ShangHai JinFeng Wine hit the daily limit up. The Ministry of Industry and Information Technology and five other departments jointly issued the "Opinions on Promoting the High-Quality Development of Historical Classic Industries" on September 7, including brewing, to which yellow rice wine belongs, in the scope of historical classic industries; a Huatai research report believed that the volume-price logic of the yellow rice wine industry is expected to undergo reconstruction. Sectors in correction The construction machinery sector was among the biggest decliners on the day, with the SW construction machinery industry index falling 4.17%. Sany Heavy Industry fell 6.72%, while Guangxi Liugong Machinery, Shantui Construction Machinery, and Jiangsu Hengli Hydraulic declined in tandem. The livestock breeding index fell 2.43%. The aviation airport, insurance, baijiu, banking, shipping port, and complete automobile concept indices fell 0.92%, 0.85%, 0.85%, 0.68%, 0.67%, and 0.31%, respectively, all within 1%.
