[Caixin.com] As global AI computing infrastructure construction continues to ramp up, demand for 800G and 1.6T high-speed optical modules is strong, and the third-quarter revenue and net profit of three domestic optical module companies located in the middle of the industry chain—Zhongji Innolight (300308.SZ), Eoptolink (300502.SZ) and T&S Communications (300394.SZ)—grew substantially accordingly. But the stock prices of all three companies have fallen for several consecutive months from their mid-year highs.

At the close on October 29, Zhongji Innolight traded at 582.05 yuan, down 8.53% for the day, with a total market value of about 685.6 billion yuan; Eoptolink traded at 228.40 yuan, down 11.06%, with a total market value of about 318.6 billion yuan; T&S Communications traded at 161.60 yuan, down 19.77%, with a total market value of about 176.3 billion yuan. Since peaking successively from late June to early July, all three stocks have pulled back more than 56%, with sharp single-day drops of nearly 9% and weeks of steady declines along the way.
