It is worth mentioning that the 2024 stocks with the highest consecutive trading days Hainan Shuangcheng Pharmaceuticals and Guangdong Songfa Ceramics are both merger and reorganization concept stocks. Hainan Shuangcheng Pharmaceuticals, which primarily deals in pharmaceutical injections, announced on December 6, 2024, the progress and risk warning for its major asset restructuring, stating that it plans to purchase 100% of Aura's shares held by 25 trading counterparts, including Hong Kong Aura Investment Co. Limited and WinAiming Limited, through issuing shares and cash payment, with plans to raise matching funds through issuing shares to no more than 35 specific investors. According to data, Aura Co., Ltd. primarily focuses on the field of analog chips and mixed-signal chips. The company successfully broke the foreign technology monopoly through the successful wafer production and mass production of its first de-jitter clock chip, and established cooperative relationships with several renowned international integrated circuit design companies, including SiTime, Renesas Electronics, and NXP Semiconductors. Analysts indicate that if Hainan Shuangcheng Pharmaceuticals successfully acquires Aura Semiconductors, it will not only facilitate the company's strategic transformation but also broaden its profit margins, as the infusion of high-quality semiconductor assets will lay a solid foundation for sustainable business development.
