On January 7, the concept of controlled nuclear fusion strengthened again. Six stocks, including China Nuclear Construction, Yeti Group, and China Machinery Heavy Equipment, rose and stopped, while individual stocks such as Yingjie Electric, Zhongtai, Valin Cable, and Huatong all rose more than 6%. Since January, controlled nuclear fusion concept stocks have continued to rise, with a cumulative increase of more than 10% for 13 stocks including Yuandong Co., Ltd. According to the news, China's controllable nuclear fusion technology is once again entering a new breakthrough. Recently, the Institute of Plasma Physics of the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences announced that the experiments of an all-superconducting tokamak nuclear fusion experimental device known as the “artificial sun” have verified the existence of a free zone of tokamak density, found a way to break through the density limit, and provided an important physical basis for high-density operation of magnetically constrained nuclear fusion devices. The relevant research results were published in the international academic journal “Science Advances”. According to statistics, there are 59 individual stocks with controlled nuclear fusion arrangements in A-shares. According to the data, R&D expenses for 22 shares accounted for more than 5% of revenue in the first three quarters of 2025. Changguang Huaxin, AGCO Cyber, Jingye Intelligence, and Juguang Technology all ranked first, with more than 20%. Looking at the year-on-year increase in R&D expenses, of the 22 shares mentioned above, R&D expenses for 16 shares increased year-on-year. Juguang Technology, Jingye Intelligence, and AGCO Cyber had the highest year-on-year increases of 87.76%, 64.87%, and 42.62%, respectively.
