On Thursday, May 28, the optical module and CPO sector experienced a broad rally. Zhongji Innolight Co.,Ltd. closed up 7.79%, Suzhou Tfc Optical Communication Co.,Ltd. rose 4.42%, and Eoptolink Technology Inc.,Ltd. gained 3.36%, with these key stocks all reaching new all-time highs. Additionally, Linktel Technologies Co.,Ltd. surged by the 20% daily limit, and Advanced Fiber Resources(Zhuhai),Ltd. jumped over 12%.
Among popular ETFs, the ChiNext AI ETF Huabao (159363), which has over 50% exposure to the optical module/CPO sector and significant holdings in the aforementioned leading stocks, climbed 3.16% intraday to set a new closing high. Its daily turnover exceeded 19 billion yuan, marking a yearly high for trading activity, with accelerated net capital inflows towards the market close. The fund saw a net subscription of 22 million units for the day.
Catalysts include Marvell Technology, a leading US optical communications company, significantly raising its revenue forecast for its optical interconnect business. The company now expects growth of over 70% by the end of fiscal year 2027, a substantial increase from its previous projection of 50% growth.
Kaiyuan Securities noted that the optical interconnect sector is currently benefiting from three favorable factors. On the computing infrastructure side, Nvidia's performance expansion trend is clear, with capital expenditures reaching new highs. On the computing application side, Anthropic achieving profitability for the first time validates the economic viability of large language models. On the computing interconnect side, the application process for CPO is accelerating, leading to a value reassessment for upstream, high-barrier segments. With these three logics converging, the importance of optical interconnect has been significantly elevated, and it is recommended to pay high attention to leading optical module companies.
Guosheng Securities stated that as we move into June, demand expectations for 2027 are gradually becoming clearer. Simultaneously, supply shortages for core upstream optical communication components are expected to gradually ease, potentially accelerating the earnings release for leading companies like Zhongji Innolight and Eoptolink. It is recommended to refocus on the major optical module theme.
