# New superconducting materials have emerged, and 17 concept stocks have shown positive year-on-year growth in performance for the first three quarters

According to Science and Technology Daily, an international research team published a paper in the latest issue of Nature Nanotechnology, stating that they have developed germanium materials with superconductivity, which can conduct electricity in a zero-resistance state, allowing current to flow continuously without loss. Achieving superconductivity in germanium opens up new pathways for developing scalable quantum devices based on existing mature semiconductor processes. According to Securities Times Data Treasure, there are 27 concept stocks related to superconductivity in the A-share market. As of the close on November 3, the total market value of these concept stocks reached 619.1 billion yuan. Since the beginning of this year, these concept stocks have averaged a 57.75% increase, significantly outperforming the Shanghai Composite Index during the same period. In terms of performance data, there are 17 superconductivity concept stocks with year-on-year net profit growth in the first three quarters of this year. Yongding Co., Goaland, Guangda Special Materials, Baosheng Co., and Haitai Development have relatively high net profit growth rates
