Zhongji Innolight's 10.47% stake and liquid-cooling/CPO demand drive Jones Tech

Zhongji Innolight buys 10.47% stake for 1.747 billion yuan Optical module giant Zhongji Innolight agreed to buy 10.47% of Jones Tech from its controlling shareholders at 55.70 yuan per share, a 1.747 billion yuan deal. The strategic investor brings confidence and potential heat-dissipation synergies as high-end optical modules ramp up. Control stays unchanged.
This is the single biggest new force behind the stock, bringing a deep-pocketed strategic partner and validating Jones Tech's thermal materials business.
China's first data center liquid cooling national standard released China approved its first national standard for cold-plate liquid cooling in data centers, effective February 2027. Tightening energy rules and AI server power density are forcing liquid cooling adoption. Jones Tech, which makes thermal materials, jumped 20% on the news as a direct beneficiary.
A new regulation creates a durable, policy-backed demand wave for Jones Tech's core thermal products.
Nvidia CPO switches enter mass production, lifting optical supply chain Nvidia said its Spectrum-X silicon photonics switches are in full mass production, cutting power use and laser counts. Jones Tech hit a second straight 20% limit as a CPO concept stock. Faster CPO adoption means more optical modules and more heat to manage, supporting demand for its materials.
It ties Jones Tech to a fast-growing technology cycle that expands the market for its thermal and shielding products.
Stake transfer registration completed, making Zhongji Innolight a major shareholder The 1.747 billion yuan transfer was registered on September 29, so Zhongji Innolight now officially holds over 5% of Jones Tech. The deal is done, not just planned. Jones Tech's first-half 2026 revenue rose 10.66% and profit rose 13.59%, and the stock is up over 122% this year.
Completion removes deal uncertainty and confirms the strategic partnership is real, a fresh milestone beyond the August announcement.

Earnings Surge and Fund Buying Offset Tax and Selloff Shocks

First-half profit forecast up 283–296% on AI data center demand DSBJ expects H1 2026 net profit of 2.9–3.0 billion yuan, up 283–296% year on year. The jump comes from data center investments, its optical module business integration, and solid consumer electronics and auto parts. This directly boosts earnings expectations and supports a higher stock price.
The profit surge is the core fundamental driver behind the stock's re-rating.
Zhang Kun adds DSBJ to top ten holdings for first time Top fund manager Zhang Kun added Dongshan Precision to his fund's top ten holdings in Q2, shifting away from baijiu toward tech growth. This signals rising institutional demand and can attract more buyers, pushing the price up.
Institutional buying is a direct demand catalyst for the shares.
New environmental tax on VOCs to raise compliance costs from 2027 China will pilot an environmental protection tax on volatile organic compounds across eight industries, including general equipment manufacturing, starting January 1, 2027. DSBJ fell 9.74% on the news as investors worry about higher compliance costs and tighter regulation.
This is a new regulatory cost that could pressure future margins.
CPO sector selloff and PCB rebound show high volatility On July 17, CPO concept stocks plunged and DSBJ hit the daily limit down amid a broad tech selloff. By July 27, the PCB sector rallied and DSBJ rebounded 6.39%. These sharp swings reflect sector-wide sentiment, not company-specific news, and add short-term trading risk.
The extreme price swings show how sector sentiment can overwhelm fundamentals in the short run.
