The eighth thousand yuan stock in A-share history is born: Yuanjie Technology tops the list

1、 A technological miracle that skyrocketed nearly 8 times in a year, from a hundred yuan to a thousand yuan

The thousand yuan journey of Yuanjie Technology can be regarded as the most shocking growth myth of A-shares in recent years. Looking back to March 20, 2025, the company's stock price was only 127.05 yuan per share. In just one year, the cumulative increase in stock price was as high as 792%, and the market value soared from billions to nearly 100 billion yuan. Since March, the company's stock price has accelerated its upward trend: on March 2, it surged 11.05% to break through the previous high point, on March 10, it surged 13.84% to stand at 900 yuan, and on March 20, it broke through the thousand yuan mark with a 20% limit up, becoming the second thousand yuan stock on the Science and Technology Innovation Board after Cambrian.

The stock price explosion this time is not accidental. As a leading provider of scarce high-speed optical chip IDM (Vertical Integrated Manufacturing) in China, Yuanjie Technology is deeply committed to AI computing power needs. Its core products, CW light sources and high-speed laser chips, are the core hardware of CPO and AIDC (Artificial Intelligence Data Centers). With the popularization of AI models such as OpenClaw, the demand for high bandwidth and low-power optical communication in global data centers is growing exponentially. Yuanjie Technology has become one of the most beneficial links in the industry chain with its technological barriers and large-scale supply capabilities.

2、 The performance turned losses into profits, and the fundamentals supported the soaring stock price

Behind the rise in stock price is a fundamental reversal in the performance of Yuanjie Technology. The company's 2025 performance report shows that it achieved a total operating revenue of 601 million yuan for the year, a year-on-year increase of 138.50%; The net profit attributable to the parent company was 191 million yuan, successfully turning losses into profits. Compared to before, the company's net profit in 2023 decreased by 80.58%, and it incurred a loss of 6.1339 million yuan in 2024. The explosive performance in 2025 is directly due to the increased volume of data center business.

Specifically, the company has achieved mass shipment of CW70mW laser chips for AI data centers, completed customer verification of 100GPAM4EML products, significantly increased the proportion of data center business revenue, and the gross profit margin of this sector is significantly higher than that of traditional telecommunications business, becoming a core driver of profit growth. At the same time, the company continues to promote its international layout. In early March, it announced its intention to issue H shares and list on the Hong Kong Stock Exchange, further opening up global market space and injecting momentum into long-term growth.

3、 A-share Thousand Yuan Stock Guide: The Track Changes from Consumption to Technology

The addition of Yuanjie Technology has further enriched the lineup of the A-share "thousand yuan stock club". Historically, a total of 7 A-share stocks have touched the price of 1000 yuan before, namely, China Security Technology, Kweichow Moutai, Yunsai Zhilian, Cambrian, Stone Technology, Homai Shares, and Aimike. From the perspective of industry distribution, early thousand yuan stocks were mostly concentrated in traditional fields such as consumption and home appliances. However, in recent years, the rise of technology stocks such as Cambricon and Yuanjie Technology marks a continuous increase in capital market recognition of hard and core technologies.

It is worth noting that only Kweichow Moutai, Cambrian and Yuanjie Technology maintain the price above 1000 yuan in the current A-share 1000 yuan camp. Among them, Kweichow Moutai, as a consumer leader, has long held the title of stock king; Cambrian reached the top with AI chip technology; Yuanjie Technology breaks through in the field of optical chips, representing the three core tracks of consumption, AI computing power, and optical communication, reflecting the direction of China's economic transformation and industrial upgrading.

4、 The field of optical chips is booming, and domestic substitution is entering a golden period

Yuanjie Technology becoming a thousand yuan stock is essentially a reassessment of the market's value in the field of optical chips. Driven by the demand for AI computing power, CPO, as the next generation optical communication technology, has become the optimal solution to solve transmission bottlenecks in data centers with its high bandwidth and low power consumption advantages, driving the continuous high demand for optical chips. As one of the few domestic enterprises with independent intellectual property rights and large-scale production of high-speed optical chips, Yuanjie Technology breaks the monopoly of overseas technology and is the core benchmark for domestic substitution.

From the perspective of industry prospects, with the popularization of 400G/800G optical modules and the advancement of 800G/1.6TCPO technology, the market size of optical chips will continue to expand. Institutions predict that the compound annual growth rate of the global optical chip market is expected to exceed 40% from 2026 to 2028, and domestic optical chip companies will further increase their market share with cost and service advantages. As a leading player in the industry, Yuanjie Technology is expected to continue to benefit from the dual logic of industry dividends and domestic substitution.
