A total of 183 institutions have conducted research on Eoptolink in the past week, including 64 fund companies, 13 securities companies, 17 sunshine private equity funds, and 14 insurance institutions. The surge in both Eoptolink's performance and stock price is inseparable from Nvidia's "catalysis". Recently, Huang Renxun announced that the "H20" chip sales will be "unbanned" soon, which has attracted the capital market to pay close attention to a number of AI industry chains; at the same time, the company's optical module business, which relies on Nvidia and other large manufacturers, has performed outstandingly and has driven its stock price to hit record highs. Compared with the issue price, Eoptolink has accumulated a total increase of more than 100 times (after adjustment). A-shares have continued to rise recently, and the Shanghai Composite Index closed at a new high this year on Friday. Institutional research stocks have risen sharply, with an average increase of more than 2% in the past week. Eoptolink, Bohui Co., Ltd., Zhijiang Bio, Zhongji Xuchuang, Pengding Holdings, etc. have all risen by more than 20%.
