Nanjing Wavelength Opto‑Electronic Science & Technology Co Ltd: Surge in a Tech‑Driven Market

Nanjing Wavelength Opto‑Electronic Science & Technology Co Ltd (stock code 301421) has captured investor attention with a remarkable 7.24 % jump on September 18, 2025, closing at 94.50 CNY—the highest price the stock has ever reached. The move brought the share price to 92.13 CNY, the 52‑week high, and pushed the market‑capitalisation to roughly 10 billion CNY.

Context: AI‑Enhanced Vision and a Rally in Optics

The rise coincides with a broader surge in the AI‑eye‑glasses segment. On the same morning, several peers—such as Yongxin Optics, Kosen Technology, and Yingcheng Vacuum—recorded gains of over 11 %, while Wavelength Opto‑Electronic hit a 20 % limit‑up. The rally is driven by a renewed focus on the integration of artificial intelligence with optical hardware, a trend underscored by Meta’s announcement of a forthcoming “Meta Connect 2025” conference where the company will showcase its AI‑glasses vision.

Institutional momentum is evident. According to the Securities Times’ “Data Treasure” dataset, 41 AI‑glasses concept stocks have attracted net borrowing from the market, with several firms projected to achieve net‑profit growth rates above 20 % in 2026 and 2027. Wavelength Opto‑Electronic itself has attracted significant capital: the company’s net purchase by the market in September surpassed 9 billion CNY, a figure that reflects a strong confidence in its growth trajectory.

Market‑Wide Conditions

The Shenzhen stock market experienced a 2.38 trillion CNY trade volume on September 18, a 353 billion CNY increase from the previous day. The three major indices—Shanghai Composite, Shenzhen Component, and ChiNext—showed modest gains, reinforcing that the optical and AI‑glass sectors were outpacing the broader market.

Institutional Flow and Deep Stock Trading

Deep Stock Trading (through the Shenzhen Stock Connect) added a net inflow of 30.15 million CNY to Wavelength Opto‑Electronic on September 17, reflecting overseas interest in the firm’s potential. Meanwhile, the Tiger List of the day recorded the company as one of the top 12 stocks that received significant net purchases from the deep‑stock‑trading seat, indicating a strategic positioning by institutional investors.
