Broker Research List Released! Wind Power, Photovoltaic, and Storage Chip Show High Popularity

Wind data shows that since the beginning of this year, securities firms have conducted over 940 investigations into A-share listed companies, mainly focusing on electronics, machinery, electrical equipment, chemicals, and other industries. Among them, 25 listed companies received visits from no less than 30 securities firms.

It is worth noting that popular stocks in the wind power and photovoltaic sectors remain highly active, and with recent increases in storage prices continuing to ferment, the investigation interest in storage chips remains strong.

Specifically, Dajin Heavy Industry has been the most followed listed company by securities firms this year, with over 90 firms conducting investigations; Tianshun Wind Power, Jinko Energy, Huqin Technology, and Nape Mining Machinery have also been investigated by no fewer than 50 firms; companies like Jingzhida, Ninebot, Weisheng Information, and Hailianxun also attract significant attention.

Wind Power and Photovoltaic Sectors Lead in Popularity, Power Equipment Becomes Key Focus of Investigations

Recently, power equipment and new energy sectors represented by wind power, photovoltaics, and grid equipment have continued to be hot topics for securities firms’ investigations. Recently, the “14th Five-Year Plan” outline was released, mentioning “strengthening the construction of new energy infrastructure” and emphasizing “promoting the safe, reliable, and orderly replacement of fossil fuels with non-fossil energy sources,坚持风光水核等多能并举，实施非化石能源十年倍增行动” (pursuing multiple energy sources including wind, solar, water, and nuclear, and implementing a ten-year plan to double non-fossil energy).

In the wind power sector, Dajin Heavy Industry is undoubtedly the “popular king,” leading the market with investigations from 95 securities firms. Since March, Dajin Heavy Industry has been visited twice by securities firms, and during investigations, the company stated that its revenue structure is mainly driven by overseas business. By the end of 2025, the company’s total overseas order backlog exceeds 10 billion yuan, mainly scheduled for delivery over the next two years, covering offshore wind projects in the North Sea, Baltic Sea, and other regions.

Similarly, Tianshun Wind Power, also in wind equipment, received intensive investigations from 58 firms. During investigations, Tianshun Wind Power noted that after the Russia-Ukraine war, Europe’s energy focus has shifted significantly toward offshore wind (offshore wind power). Over the next decade, with the participation of local European, Chinese, and Southeast Asian supply chains, the certainty of European offshore wind will increase. Additionally, companies like Zhenjiang Shares and Taisun Wind Power have also attracted investigations from more than 10 firms.

The photovoltaic sector remains equally hot. Jinko Energy and Dico Co., Ltd. received investigations from 52 and 42 firms respectively. Companies along the photovoltaic industry chain such as Trina Solar, Canadian Solar, and Daqo New Energy also received attention from over 20 firms. The focus of investigations includes technological iteration, overseas market expansion, and industry chain price trends.

In the grid equipment field, Siyuan Electric, Huaming Equipment, and Haixing Electric have been investigated by more than 10 firms. With the release of the “14th Five-Year Plan” and the expected 4 trillion yuan in fixed asset investment by the State Grid Corporation, the future growth potential of related companies has attracted strong interest from institutions.

Storage Chips Continue to Rise, Multiple Concept Stocks Gathered for Investigations

Storage chips have also been a recent focus of securities firms’ investigations. As the semiconductor cycle gradually warms up and downstream demands such as AI and high-performance computing drive growth, the industry’s prosperity has significantly rebounded.

Since the beginning of this year, global storage chips have entered a new round of price increases. On March 18, cloud providers like Alibaba Cloud and Baidu Smart Cloud simultaneously raised prices for AI computing power and storage products, with increases of up to 34%. Recently, OPPO and Vivo also announced price hikes for their smartphones.

Wind data shows that multiple storage chip and related concept stocks have attracted high attention from securities firms. Institutions generally focus on storage chip price trends, domestic substitution progress, and companies’ expansion into emerging fields.

Among them, Dongxin Co., Ltd. has been investigated 7 times this year, with a total of 38 securities firms paying attention, making it one of the most investigated companies in the storage chip field. As a relatively pure storage chip design company in the A-share market, its SLC NAND products are widely used in industrial and communication fields. Dongxin stated during investigations that its 1xnm flash memory products have achieved mass production, with continuous design and process optimization, significantly improved product reliability, and successful sales.

Jiangbolong and Baiwei Storage, representing storage modules and packaging/testing fields, have also been investigated multiple times this year, attracting many securities firms. Additionally, companies like Huqin Technology, Aisen Co., Ltd., and Hengkun New Materials, due to their key positions in the industry chain, have also received intensive investigations.

Securities Firms Are Generally Optimistic About the Future Market

Recently, many securities firms have held strategy meetings or released spring strategies, remaining generally optimistic about the market outlook.

CITIC Securities’ chief A-share strategist Qiu Xiang believes that the spring A-share market is at a critical juncture. The focus in the next phase will shift from valuation to profit margins. Low valuation and pricing power are the two most important factors; low valuation is the strongest shield. Favorable valuation is better than high valuation, value investing is better than growth, and large caps outperform small caps. In terms of allocation, they advocate firmly focusing on China’s advantageous manufacturing and pricing power.

Zheshang Securities believes that as the Shanghai Composite Index consolidates upward, the industry is expected to undergo a more comprehensive revaluation. The industry allocation strategy is to “balance new and old energy, and enhance cyclical consumption.” They suggest focusing on four main directions: 1) power equipment benefiting from “computing and electricity synergy” and supply chain clearing (photovoltaics, wind power, lithium batteries); 2) under the HALO trading environment, traditional industries are expected to see value revaluation, including power, communications services, glass fiber, general steel, coke, gas, and coal mining, as well as communication services, power, and grid equipment; 3) cyclical products spreading internally, paying attention to relatively lagging basic chemicals, agriculture, forestry, animal husbandry, and fishery; 4) in consumer segments, such as biomedicine (innovative drugs) and consumer services.

Shenwan Hongyuan believes that confidence should be maintained. The first half of this year is unlikely to be the peak of this round of market, and a new wave of gains may start in the second half of 2026, extending into the first half of 2027. This will be driven by nonlinear changes in fundamentals and accelerated inflows of incremental funds.
