Goldman Sachs raised its Zhongji Innolight H-share long position to 10.57 percent, while Morgan Stanley increased its stake to 8.3 percent, HKEX filings show.
The changes were disclosed in Hong Kong Exchanges and Clearing filings on Aug. 21. Goldman Sachs' long position rose from 9.33 percent on Aug. 17, while Morgan Stanley's increased from 8.15 percent on Aug. 18.
Zhongji Innolight is a leading optical module manufacturer whose products support AI data center infrastructure. The company's H-shares trade on the Hong Kong Stock Exchange, alongside its A-shares on the Shenzhen Stock Exchange. The stock price reaction to the filings was not immediately available.
The simultaneous increases by two of the world's largest investment banks reflect strong institutional confidence in the company. The optics and AI infrastructure sector could see additional buying interest from other institutional investors as a result.
The increases come as demand for high-speed optical transceivers continues to grow with AI data center buildouts. Zhongji Innolight supplies optical modules to major cloud and AI infrastructure providers, making it a key supplier in the AI compute supply chain.
Morgan Stanley's increase of 15 basis points and Goldman Sachs' increase of 124 basis points represent meaningful position adjustments for both institutions. The Goldman Sachs increase is particularly notable, crossing the 10 percent threshold, which may trigger additional disclosure requirements under HKEX rules.
The dual increases follow a period of sustained demand for optical interconnect solutions from hyperscale cloud providers. Companies such as Nvidia and Microsoft have been expanding AI infrastructure capacity, driving demand for the high-bandwidth optical modules that Zhongji Innolight produces. The company competes with other optical module makers including Coherent and Lumentum in the global market.
For holders, the dual increases suggest institutional conviction in the company's growth trajectory. Investors will watch for further HKEX disclosures and the company's next earnings report for updated guidance on revenue and margin trends. The position increases also come at a time when global investment banks are selectively increasing exposure to AI infrastructure names, a trend that could support further inflows into the sector.
