Wuhan wins the gamble! Hubei welcomes its first company with a market value of 200 billion yuan, with the big bull stock Changfei Optical Fiber soaring over 10 times, AI computing power + hollow-core optical fiber driving the stock price, far exceeding institutional expectations.

How does the AI and AI computing power boom drive explosive growth in fiber optic demand?

Wuhan’s leading stock, Changfei Fiber, continues its “unstoppable” journey. On April 2, the A-share market saw a broad correction; the Shanghai Composite Index fell by nearly 1%, and the Shenzhen Component Index dropped by more than 2% in the afternoon. Changfei Fiber’s stock price hit the daily limit, reaching a high of 338.80 yuan. In nearly 8 trading days, it fell only once, with a cumulative gain as high as 56%, and market trading activity remained highly active.

Since 2025, Changfei Fiber’s stock price has surged from under 30 yuan to above 330 yuan, with a cumulative increase of more than 10 times; during this period, the highest rise reached 12 times. Changfei Fiber in Hong Kong also showed strong performance: in 2024, when its share price hit the lowest point, it was only 6.4 HKD; this year, in March, it climbed to a peak of 206.8 HKD, with the highest increase reaching 31 times.

From the perspective of market performance, Changfei Fiber has become an undisputed core leader in the fiber optic industry. Guotai Junan Securities previously released a report, raising its target price to 293.87 yuan. Its key logic points to two major directions: the breakout of AI computing power and the commercialization of hollow-core fiber optics. At that time, the market already had strong expectations; yet the current stock price has far surpassed that target price.

The core logic driving market speculation in Changfei Fiber is concentrated in the combined resonance of three layers of catalysts. First, the pace of AI computing power infrastructure construction is accelerating. Globally, data centers are seeing an explosive surge in demand for high-end fiber optics; a 10,000-GPU cluster requires the consumption of tens of thousands of high-end fiber cores. As the world’s largest supplier of fiber preforms, fiber optics, and cables, Changfei Fiber directly benefits from this trend. Second, a fundamental reversal has occurred in the supply-and-demand landscape of the fiber optic industry: the price of G.652.D fiber has risen sharply, and the logic of both volume and price rising together is clear. Third, Changfei Fiber has globally leading technology reserves in the hollow-core fiber optics field. Compared with traditional solid-core fibers, hollow-core fibers have lower latency and faster transmission speeds, and are viewed as the next-generation core material for interconnecting AI data centers. The market positions it as the “shovel-seller” in the AI computing power era.

On the news front, Changfei Fiber recently disclosed its annual report data. For full-year 2025, its total operating revenue was 14.252 billion yuan, up 16.85% year over year; net profit was 814 million yuan, up 20.4% year over year; earnings per share were 1.07 yuan. Its sales gross margin was 30.73%; operating cash flow per share was 4.4122 yuan. The results show a steady growth trend.

It is worth noting that after this round of big gains, Changfei Fiber’s market capitalization has exceeded 2000 billion yuan. Among this, the A-share market capitalization is about 1350 billion yuan, and the Hong Kong market capitalization is about 710 billion yuan. It is not only Hubei Province’s “No. 1” listed company by market capitalization, but also the first listed company with a market capitalization exceeding 2000 billion yuan.

Changfei Fiber is located in Wuhan, the core base of China’s fiber optic and cable industry. It mainly relies on the Wuhan East Lake High-tech Development Zone—the famous “Optics Valley.” It has a complete manufacturing industrial chain with Changfei Fiber as the leading player. In addition, the Optics Engineering discipline at Huazhong University of Science and Technology behind Optics Valley has consistently ranked No. 1 in China.
