Major market indices opened higher today (January 16) before the Shanghai Composite Index turned negative. The power equipment and electronics sectors led the gains. In market movements, the power grid equipment sector experienced a surge of limit-up stocks, with more than 10 stocks, including Hanlan Cable, Guangdian Electric, and Baobian Electric, hitting their daily limit-up. Reports indicate that State Grid Corporation announced that its fixed asset investments during the "16th Five-Year Plan" period will reach 4 trillion yuan, a record high representing a 40% increase compared to the "14th Five-Year Plan" period. The semiconductor sector also performed strongly, with stocks like Pairomicro, Kingsemi, and Tianyue Advanced rising over 10%. Memory chip concepts were particularly robust, with leaders including Jingce Electron, Lanjian Electron, and Biwin Storage. Among individual stocks, *ST Chengchang, Tiansheng New Materials, and Zhite New Materials resumed trading today. *ST Chengchang (001270) experienced an instant "heaven-to-earth" rebound after opening, having secured 10 limit-ups in the 11 trading days prior to its suspension, bringing its total to 11 limit-ups including today. The stock has been a major performer in the recent commercial aerospace theme. The company stated in a previous abnormal volatility announcement that the commercial aerospace industry is in its early stages, and the progress and timing of batch launches and network deployment for low-orbit satellite constellations remain uncertain. After suspending trading for verification on January 13, the company resumed trading today following the release of its verification results, indicating that while its stock's short-term gains significantly outpaced the sector and the Shanghai Composite Index, no major changes have occurred in its fundamentals, and significant trading risks exist. Tiansheng New Materials opened close to its limit-up upon resuming trading. The company plans a private placement to Rongsheng Zhirui. Upon completion, Rongsheng Zhirui will directly hold 13.30% of the company's shares. Concurrently, its acting-in-concert party, Rongsheng Xintai, intends to acquire a 5.45% stake via a share transfer agreement. After the completion of both transactions (excluding equity incentives), Rongsheng Zhirui and its acting-in-concert parties will collectively hold 18.75% of the shares, making Rongsheng Zhirui the new controlling shareholder and YU Lidong the new actual controller. Zhite New Materials fell sharply after resuming trading, at one point dropping over 19%. The stock had experienced consecutive limit-ups over just a few trading days from January 5 to January 12, accumulating gains of nearly 200%. The rapid price appreciation suggests overheated market sentiment and a pronounced "pass the parcel" effect. The company clarified that, to date, its business does not involve AI applications, artificial intelligence, quantum technology, robotics, or commercial aerospace, and it has not generated any related revenue.
