One Year to Success: Why SourceJet Technology Became the 8th Stock to Break the Thousand-Yuan Barrier

On the morning of March 20, 2026, the A-share market experienced a historic moment. The popular stock of the CPO (Co-packaged Optics) concept, Yuanjie Technology (688498.SH), once hit the daily limit-up, with the stock price reaching a high of 1,140.00 yuan per share. This marked its first entry into the “Thousand-Yuan Stock Club” and also saw the stock price surpass Cambrian (688256.SH), making it the second-highest priced stock in the A-share market, only behind Kweichow Moutai (600519.SH).

After 10:55 AM, the stock price hit the limit again, and by the midday trading halt, Yuanjie Technology was approaching the limit-up again, closing at 1,138.42 yuan per share. The trading volume exceeded 47,000 lots, and its total market value approached 100 billion yuan.

Founded in 2013, Yuanjie Technology focuses on the research, design, production, and sales of optical chips. It is one of the few domestic companies capable of independently developing and manufacturing semiconductor laser chips. In the optical communication field, its main products include 2.5G, 10G, 25G, 50G, 100G, 200G, and higher-speed DFB and EML laser series, as well as high-power CW laser chips used in silicon photonics solutions. It is also the first domestic manufacturer to successfully produce 25G lasers.

On December 21, 2022, Yuanjie Technology was listed on the STAR Market. However, in 2023 and 2024, due to weak telecom markets and price competition, its performance remained under pressure, and its stock price hovered around the hundred-yuan mark.

In 2025, Yuanjie Technology’s performance turned around. According to previous earnings reports, in 2025, its total operating revenue reached 601 million yuan, a year-on-year increase of 138.50%; net profit attributable to shareholders was 191 million yuan, surging over 32 times year-on-year, successfully returning to profitability. The company explicitly stated that the significant growth in sales of CW light source products in data centers and the optimization of product structure were the main drivers of performance growth.

The explosive growth in global AI computing power demand is the direct reason for Yuanjie Technology’s rapid expansion. On one hand, AI has moved from technological breakthroughs to practical applications, with large-scale deployment of consumer and enterprise models, driving exponential growth in token consumption; on the other hand, the focus of computing power demand has shifted from model training to real-time inference. These dual factors have jointly caused global AI computing power demand to grow at an annual rate of 4 to 5 times.

Against this backdrop, optical chips, as a core component of the optical communication industry chain, are experiencing rising demand. Yuanjie Technology’s CW 70mW laser chips for 400G/800G optical modules have achieved mass shipment, and CW 100mW products have also been validated by customers.

Recently, Yuanjie Technology plans to further expand its business footprint by issuing overseas-listed shares and applying for listing on the Main Board of the Hong Kong Stock Exchange.

From a low of 87.70 yuan per share in early April 2025 to 1,140 yuan per share on March 20, 2026, Yuanjie Technology has increased more than tenfold in less than a year, making it one of the most explosive stocks in this round of AI market rally.

In the long history of the A-share market, only seven stocks have previously reached the thousand-yuan level: Kweichow Moutai, Cambrian, Zhong An Ke (600654.SH), YunSai ZhiLian (600602.SH), Stone Technology (688169.SH), Hema股份 (688032.SH), and Aimeike (300896.SZ). Among them, Kweichow Moutai has long held the top spot, while Cambrian reached a new high in 2025 and has remained high since. Now, Yuanjie Technology’s rise has broken the previous pattern of high-priced stocks.
