Shanghai, Jan 26, 2026, 06:05 (GMT+8) — Premarket
- Zhongji Innolight’s A-shares ended at 585 yuan, slipping 5.8%.
- Fund disclosures reveal the optical-module maker ranks as the largest holding among active equity mutual funds.
- Shareholders will vote on Jan. 28 regarding a plan linked to an H-share offering and a Hong Kong listing.
Zhongji Innolight Co., Ltd.’s Shenzhen-listed Class A shares dropped 5.8% by Friday’s close and are set to open Monday lower. The slide contrasts sharply with new data revealing the stock as the largest holding in China’s active equity mutual funds. 1
The shift highlights just how aggressively institutions have piled into the AI-hardware supply chain, with positioning—not just earnings—now steering daily fluctuations. A Shanghai Securities News report noted AI themes taking center stage in public-fund portfolios, as Zhongji Innolight surged to the top spot. 2
Wind data, cited in a report by Huaxia Times, showed that 1,273 active equity funds held Zhongji Innolight at the end of Q4, with those holdings making up 12.24% of its free float. Wu Zewei, a researcher at the Star Map Financial Research Institute, described the reshuffle as a “clear signal” that institutional investors are shifting their bets from last cycle’s new-energy leaders to AI computing hardware. On the other hand, Li Fumin, a senior partner at Shandong Longquan Law Firm, cautioned that heavy clustering could heighten volatility once the trade reverses. 3
Zhongji Innolight produces optical transceiver modules—devices that convert electrical signals into light for fast data connections—and investors see it as a direct play on data-centre investment. The broader “optical-module” sector has drawn significant fund interest, with rivals like Eoptolink also ranking prominently in recent fund-holding reports.
Friday brought a block trade of 43,900 shares, totaling roughly 25.69 million yuan, at 585 yuan each, according to exchange data. 4
Zhongji Innolight is set for an extraordinary shareholders’ meeting on Jan. 28, according to a recent company filing. Among the key agenda points: an IPO for overseas-listed shares (H-shares) and a planned debut on Hong Kong’s main board, plus several governance proposals and related motions. 5
On Friday, the stock dropped to 585 yuan from a previous close of 621 yuan, swinging between 580.16 yuan and 615.00 yuan during the session, according to data from Securities Times. That data also pegged Zhongji Innolight’s market value at roughly 650 billion yuan, with a price-to-earnings ratio sitting at 68.36. 6
The crowding story isn’t straightforward. Taiwanese media pointed out that despite Zhongji Innolight climbing to the top of active-fund rankings, funds actually reduced their share count in the fourth quarter. This highlights how a “top holding” can signal price appreciation just as much as new buying. 7
The risk is clear: crowded trades can unravel quickly. A dip in demand from overseas cloud clients, a faster-than-anticipated tech shift, or an earnings report that misses lofty expectations might flip fund concentration from a boost into a burden.
After this week’s shareholder vote, attention shifts to earnings season. According to Eastmoney’s calendar, Zhongji Innolight is set to release its 2025 annual report on March 31. 8
Key markers to watch: the shareholder meeting on Jan. 28 and how the stock moves once Shenzhen opens Monday. Will buyers see Friday’s dip as a buying opportunity or the beginning of a sell-off?
