Shanghai — Feb 8, 2026, 08:33 GMT+8. The trading session wrapped up; markets are now closed.
Zhongji Innolight Co Ltd (300308.SZ) shares dropped 3.9% to close at 540.01 yuan on Friday. The optical transceiver manufacturer, traded in Shenzhen, could see renewed attention when China’s A-share markets resume trading Monday. 1
Why it’s on the radar now: Zhongji has turned into a flashpoint for China’s “AI infrastructure” trade, as local media note its heavy fund exposure. The report also flagged that the broader optical-module space is feeling the squeeze, with U.S. tech volatility and shifting projections for AI-fueled data-center demand weighing on the sector. 2
Zhongji’s latest forecast tells a different story. In a Jan. 31 filing, the company projected 2025 net profit attributable to shareholders between 9.8 billion and 11.8 billion yuan—an increase of 89.50% to 128.17% on the year. Management credited the jump to robust shipment growth and a larger share of high-speed products in its portfolio. 3
The filing pointed to a few volatile items that can throw off quarterly results: equity incentive expenses, shifts in inventory, credit-loss provisions, and foreign-exchange losses as the U.S. dollar softened. 3
CFO Wang Xiaoli and board secretary Wang Jun told investors that a large portion of customer orders are booked all the way through Q4 2026, according to an investor-relations record. That same document noted that ramp-up is underway for 800G and 1.6T products, though upstream supplies—particularly some optical chips—remain tight. 4
Simply put, 800G and 1.6T are shorthand for ultra-fast data rates—800 gigabits per second and 1.6 terabits per second, respectively—typical in top-tier data center connections.
Friday’s action said it all. Shares swung from 530.30 yuan to as high as 561.88 yuan, with closing data showing turnover hit roughly 17.91 billion yuan. 5
Some on the Street say the recent slide has more to do with positioning than anything fundamental. A Sina fund report flagged profit-taking after strong earnings forecasts and noted that “shareholder reduction” is weighing on sentiment in the short run. On the flip side, capex plans from North American cloud providers got a positive mention in a CITIC JianTou Securities note. The same report quoted ETF manager Cao Xuchen, who called optical modules a “clear industry trend.” 6
That’s the backdrop traders face as they head into Monday. When the sector finds its footing, Zhongji tends to be where dip buyers make their first move—just as quickly, it’s also the spot they exit if sentiment sours.
Still, there’s a clear risk here: a slowdown in the global AI capex story, or a pickup in selling from big holders, could quickly send this crowded trade into reverse. Throw in supply snags and currency moves, and you’ve got a stock that could stay choppy—even if the headline profits keep coming in strong.
Earnings are up next. According to TradingView’s calendar, Zhongji is scheduled to release results March 31. Shares have slid roughly 12% over the last week, pulling back from their late-December highs. 7
