On April 10, shares of Eoptolink Technology Inc., Ltd., a leading player in the optical module sector, rose over 3% during trading, hitting another record high. The company's total market capitalization surpassed 500 billion yuan, marking a cumulative increase of more than 830% over the past year. The ChiNext AI ETF Hua Bao (159363), which holds significant positions in the "Yi Zhong Tian" portfolio of optical module leaders, also surged over 2% to a new all-time high.
Eoptolink's stock has continued its upward trend recently, climbing more than 3% and pushing its total market cap above the 500 billion yuan threshold, underscoring its dominant position in the CPO (co-packaged optics) field. As a core component of the "Yi Zhong Tian" portfolio—which includes Zhongji Innolight, Eoptolink, and TFC Optical Communication—both Eoptolink and Zhongji Innolight reached new historical highs today. At one point, their combined stock value even exceeded that of Kweichow Moutai, reflecting strong market expectations for the CPO segment. Although some margin traders have recently reduced their holdings in Eoptolink, its margin balance remains among the highest in the A-share market, indicating sustained long-term optimism amid divergent views.
The CPO sector's activity is benefiting from persistent demand-side drivers, with several stocks in the segment seeing average daily trading volumes exceeding 10 billion yuan, supported by frequent participation from quantitative and institutional funds. Among high-priced stocks, the TMT (technology, media, and telecommunications) sector accounts for nearly 85%, with electronics and communications playing a dominant role. Sub-sectors such as semiconductor equipment and digital chip design have shown particularly strong performance. This trend aligns with the rise of former stock champions like Cambricon and Yuanjie Semiconductor Technology, highlighting the growing weight of tech stocks in the A-share market.
Eoptolink's market cap growth is not an isolated case. Several other tech leaders, such as Biwin Storage, have seen their market capitalizations break through the 100 billion yuan mark this year, with margin traders noticeably increasing their positions. This further confirms the shift of capital toward the technology sector. Overall, the high growth momentum in the CPO and semiconductor industries continues to drive related stocks to new highs, though attention should be paid to fluctuations in margin financing and valuation divergences within the sector.
The CPO concept remained active today, with leading stock Eoptolink rising over 3% and reaching a fresh record high. Its one-year gain of more than 830% and market cap exceeding 500 billion yuan reflect the sustained high growth of the computing power industry chain, fueled by global AI demand. Recent announcements from Alibaba about increasing investments in AI computing infrastructure, along with ongoing data center and cloud computing investments by international giants like Google and Microsoft, are directly boosting demand for hardware such as optical modules. On the policy front, the Central Economic Work Conference emphasized "innovation-driven development" and "cultivating new growth drivers," suggesting continued benefits for the hard-tech sector. Within the segment, stocks like Zhongji Innolight and Changguang Huaxin also strengthened, showing strong market consensus on the computing power theme. However, caution is warranted as stocks with large short-term gains may face technical corrections; investors should monitor earnings performance and global AI capital expenditure trends.
As a leader in the optical module industry, Eoptolink's stock rose over 3% to a new historical high, with its total market cap surpassing 500 billion yuan and a one-year increase of more than 830%. This fully demonstrates its leading position in the CPO field and high market recognition. As a core member of the "Yi Zhong Tian" portfolio, Eoptolink, together with Zhongji Innolight, has driven sector activity, benefiting from surging AI computing demand, rapid cloud computing development, and growth in cryptocurrency, which continue to boost industry sentiment.
On the policy side, the Central Economic Work Conference highlighted innovation-driven development and technological self-reliance, while global AI leaders like Google and Microsoft have signed power purchase agreements and made forward-looking investments, providing long-term tailwinds for the optical module industry chain.
In terms of capital flows, although margin traders show some divergence, Eoptolink's margin balance remains high among A-shares, with frequent participation from institutional and quantitative funds. Average daily trading volumes exceeding 10 billion yuan reflect the capital shift toward the technology sector. Strong demand-side drivers, a recovery in the semiconductor industry boosting soldering material demand, and the TMT sector's nearly 85% representation among high-priced A-shares—with electronics and communications in dominant roles—further underscore the sector's high growth. The rise of tech stocks like Cambricon and Yuanjie Semiconductor Technology also validates the industry's robust momentum.
Eoptolink's market cap growth is not an exception. Other tech leaders like Biwin Storage have broken the 100 billion yuan market cap level, with margin traders increasing their positions significantly, highlighting the rising weight of tech stocks and high expectations for the CPO segment. Against a backdrop of policy support, technological iteration, and global liquidity easing, Eoptolink and the optical module industry are well-positioned to benefit, driving both earnings and valuations higher.
