Sourcejet Technology Stock Price Breaks 1000: The Comeback Journey from Valley to Peak, Nearly 7x Return in One Year

In the A-share market, the “second-place” stock price has recently changed hands again. A company called Yuanjie Technology has become the market focus with its impressive performance, with its stock price breaking through the 1,000 yuan mark and ranking as the eighth stock in A-shares in history to reach this level.

After the market opened that day, Yuanjie Technology’s stock price rose rapidly, hitting the 20% daily limit around 10 a.m., soaring to 1,140 yuan, and breaking through the key thresholds of 1,000 and 1,100 yuan consecutively. Although the limit was opened during trading, by 2 p.m., the increase remained at 17.76%, successfully surpassing Cambrian, which had fallen sharply that day, making it the second-highest priced stock in A-shares. This eye-catching performance quickly propelled Yuanjie Technology to trending searches with labels like “second-highest stock price” and “thousand-yuan stock.”

Yuanjie Technology’s surge was not accidental but riding the strong momentum of the CPO sector. By 2 p.m., many leading stocks in the CPO sector had surged significantly, with Yuanjie Technology standing out as a shining star due to its remarkable gains.

Looking back over the past year, Yuanjie Technology’s stock performance has been extraordinary. Since March 20 last year, the company’s stock price has increased approximately 6.9 times; if calculated from the beginning of 2025, the total increase exceeds seven times. Starting from a low of 87.99 yuan in April last year, the maximum cumulative increase was nearly 12 times. Over 12 months, the monthly chart showed an unusual pattern of 11 bullish months and only 1 bearish month, demonstrating a remarkably strong trend.

The explosive growth in Yuanjie Technology’s stock price is closely linked to its deep accumulation in the optical communication field. At the recent 2026 NVIDIA GTC conference, Jensen Huang showcased the world’s first mass-produced CPO switch and announced that three technical routes—copper cable expansion, intra-node optical expansion, and inter-node optical expansion—will be advanced simultaneously, with partners needing to increase production continuously. This news has brought huge opportunities to the optical communication industry, and the widespread adoption of CPO packaging optical technology hinges on breakthroughs in external light sources, which is Yuanjie Technology’s core advantage.

As a key supplier of domestic EML and continuous wave lasers, Yuanjie Technology has made deep inroads into AI data centers. The company’s main business covers the research, design, production, and sales of optical chips, including 2.5G, 10G, 25G, 50G, 100G, 200G, and higher-speed DFB and EML laser series, as well as high-power silicon photonic light sources, widely used in fiber-to-home, data centers, cloud computing, 5G mobile networks, backbone communication networks, and industrial IoT sectors.

Since listing on the STAR Market in 2022, Yuanjie Technology’s performance has experienced ups and downs. In 2023, due to underperformance in the telecom and data center markets, as well as intensified price competition for some products, the company achieved revenue of 144 million yuan, down 48.96% year-over-year; net profit attributable to shareholders was 19.5 million yuan, down 80.58%, and it also received inquiries from the Shanghai Stock Exchange. In 2024, the company’s overall revenue still mainly came from the telecom sector, with a high proportion of mid- and low-speed products. Affected by industry downturns and fierce market competition, revenue recovered to 252 million yuan, up 74.63% year-over-year, but net profit turned negative, recording -6.13 million yuan, down 131.49%, and the stock price once fell nearly 70% from its high.

A turning point came in 2025. With the explosive growth in global AI computing power demand, the optical chip industry has entered a development phase. According to the latest earnings report, Yuanjie Technology’s total revenue in 2025 reached 601 million yuan, up 138.50% year-over-year; net profit attributable to the parent company was 191 million yuan, successfully turning profitable. The company stated that under the continuous growth of AI technology-driven optical chip demand, leveraging its technological and product advantages, optimizing resource allocation, it achieved significant sales growth of CW light source products in data centers, increased the proportion of data center business revenue, and further optimized its product structure.

EML lasers and continuous wave lasers are the most technically challenging core components in optical modules. Against the backdrop of rapidly increasing AI computing power demand, Yuanjie Technology’s data center business has grown substantially, especially the high-power CW laser chips needed for silicon photonics solutions, which have been supplied to industry leaders such as Zhongji Xuchuang and Tanfeng Communications. According to Goldman Sachs research, the company has achieved mass production of 70mW continuous wave lasers and has been validated by customers with 100mW products, gaining an early advantage in mainstream 800G/1.6T optical module technology routes. The gross profit margin of data center products is higher than that of traditional telecom products, becoming an important support for profit growth.

While achieving impressive results in the capital markets, Yuanjie Technology is actively planning for future development. The company plans to issue shares overseas (H-shares) and apply for listing on the Main Board of the Hong Kong Stock Exchange to complete a dual-platform “A+H” layout. It is also expanding production capacity.

However, Yuanjie Technology also faces many challenges. Technologically, the optical chip industry’s technological routes are evolving rapidly. While its CW light sources perform well in the current 400G/800G era, emerging technologies like thin-film lithium niobate are also developing quickly. As a core optical source supplier, whether its technology can perfectly adapt to new modulation schemes and whether its production capacity can keep pace with industry shifts to next-generation technologies remain to be seen. In terms of internationalization, the company plans to list in Hong Kong and promote the construction of a U.S. manufacturing base, but in 2024, overseas revenue was only 237,400 yuan, and in the first half of 2025, it was just 25,560 yuan. Meanwhile, the global demand for AI computing power is mainly overseas. This means the company will face direct competition in international markets from established giants like Lumentum and Coherent, which possess deep technological patents and strong customer loyalty.
