On March 18, the A-share market experienced fluctuations and differentiation during trading. The computing power leasing, CPO optical module, and cloud computing-related sectors in the technology track all strengthened, with the computing power sector actively thriving against the trend due to strong industrial logic. The cloud computing ETF (159890), which tracks the CSI Cloud Computing and Big Data Theme Index, rose 2.6% during the trading session as of the time of publication.
In terms of constituent stocks, Data Harbor hit the daily limit, leading optical module company Eoptolink rose over 6%, and Zhongji Xuchuang increased by over 4%; the computing hardware sector also performed well, with Unisplendour rising over 3%, Inspur Information up over 2%, and Zhongke Shuguang increasing by over 1%; in the computing service sector, Dongfang Guoxin rose over 16%, highlighting the upstream and downstream linkage effects in the industrial chain.
The outbreak of the computing power sector's market this round is primarily due to the intensive catalysis of multiple news events. On March 18, Alibaba Cloud officially announced price increases of up to 34% for AI computing power and storage products, with the price of the PingTouGe computing card rising by 5%-34% and intelligent storage increasing by 30%, further validating the tense supply-demand pattern in the industry; prior to this, cloud service providers both domestically and internationally, including AWS, Google Cloud, and Tencent Cloud, had successively initiated price adjustments, with Tencent Cloud's Hunyuan model increasing by over 400%, completely breaking the cloud computing industry's more than ten-year tradition of &#34;only decreasing and not increasing,&#34; officially confirming the global cloud service price increase cycle.
At the same time, the OFC 2026 conference focused on 1.6T optical communication technology, and NVIDIA's Feynman chip is accelerating the implementation of chip-level optical communication, with the CPO industrialization process continuing to accelerate, providing ongoing industrial catalysis for the computing power industry chain.
In terms of capital flow, the cloud computing ETF (159890) saw a cumulative net inflow of over 30 million in four out of the last five days, with major funds in the morning session focusing on the three main technology lines of electronics, communications, and computers. Eoptolink ranked among the top in net capital inflow across the market, with funds in the cloud computing sector precisely targeting high-boom segments such as upstream hardware, optical modules, and computing power leasing.
CITIC Securities pointed out that the market in March should focus on the inflation main line of the computing power chain, with domestic and foreign computing power demand expected to continue to exceed expectations, and the prosperity of upstream hardware and optical communication segments being more prominent. Meanwhile, Guojin Securities also stated that the growth slope of domestic computing power demand continues to rise, and the price increases by cloud service providers effectively validate the improvement in industry ROI, with the prosperity of the entire domestic computing power industry chain expected to accelerate.
As an efficient tool for laying out the computing power industry, the cloud computing ETF (159890) precisely covers the two core segments of AI computing power (41%) and AI applications (32%), with artificial intelligence content reaching 41%. The top ten holdings include leading companies in the software and hardware fields such as iFlytek, Kingsoft Office, Zhongji Xuchuang, Eoptolink, and Inspur Information.
