The lithium battery industry chain is active, with Haike Xinyuan stock price hitting an all-time high

In this week’s list of top-performing stocks (excluding newly listed stocks in the past month), several lithium battery and green energy concept stocks led in gains. Among them, Haike Xinyuan (301292.SZ) surged over 51% in a single week, setting a historic high in stock price, becoming this period’s top stock. Lianxiang Co., Ltd. (603272.SH) rose over 48% in the past week, ranking second. Additionally, Rongjie Co., Ltd. (002192.SZ), Huadian Liaoneng (600396.SH), and Jiemite (300868.SZ) all saw gains of over 40%.

The top stock Haike Xinyuan belongs to the lithium battery material industry chain and is a leader in lithium battery electrolyte solvents:

According to the 2025 semi-annual report information, the company has been focused on the research, production, and sales of carbonate series lithium-ion battery electrolyte solvents, additives, and high-end propylene glycol and other fine chemicals, building a “lithium battery materials + consumer chemicals” dual-driven pattern.

• Lithium battery electrolyte materials: High-quality clients, occupying an A-supply position among leading electrolyte companies such as Tianci Materials, BYD, Ruifeng New Materials, enchem, soulbrian, and Mitsubishi; actively expanding the second growth curve, laying out new additives, solid electrolytes, and new solvents for lithium battery electrolytes.
• Consumer chemicals: The company is one of the main domestic manufacturers of food-grade and pharmaceutical-grade polyol products, and one of the earliest enterprises in the country to achieve stable mass production of bio-based 1,3-butanediol.

The company’s performance forecast for 2025 shows an expected net loss of 175 million to 197 million yuan, with the loss amount reduced. During the reporting period, relying on the rapid development of downstream new energy vehicles and energy storage markets, the market demand for the company’s main products, electrolyte solvents, and additives continues to rise. In addition, the main products of electrolyte solvents and additives are expected to see price increases in late November 2025, but due to the proximity to the year-end, the driving effect on annual profitability was not fully released.

In the secondary market, on March 27, Haike Xinyuan hit the 20% limit up, with stock prices reaching an all-time high, previously rising over 16% on March 26, with a cumulative increase of over 51% for the five trading days of the past week.

In fact, in addition to Haike Xinyuan, Rongjie Co., Ltd. in this week’s top stocks also belongs to the lithium battery industry chain, related to lithium mining concepts.

Recently, in the face of weak market conditions, the new energy sector represented by lithium batteries has strengthened against the trend, with related concepts such as lithium mining, electrolytes, lithium battery anodes, and sodium-ion batteries repeatedly gaining strength, among which, on March 26, the lithium battery electrolyte sector surged, and on March 27, lithium mining concept stocks collectively exploded.

Some media pointed out that geopolitical conflicts in the Middle East have caused international oil prices to soar, which, while driving up oil and related sectors, has also boosted market attention towards the new energy industry chain. Taking this crisis as an opportunity, further strengthening energy security through new energy has become a focus for many institutions.

CITIC Securities’ research report pointed out that in the short term, against the backdrop of a significant rise in oil and gas prices, the new energy industry is expected to benefit from its flexible allocation attributes and improved economic advantages, leading to accelerated demand growth; in the medium to long term, there is a shortfall in oil and gas resources in China, Europe, and the Asia-Pacific region, and the development of clean energy will shift from a low-carbon transition optional path to a necessary strategy for ensuring energy security.

Stock price hit the limit down three times, why did Huada Technology become the worst stock?

The worst stock Huada Technology belongs to the automotive parts industry:

Public information shows that the company mainly engages in the development, production, and sales of passenger car body parts, related molds, and battery boxes, motor shafts, motor casings, and energy storage boxes for new energy vehicles. Its products include stamped and welded products such as automobile body components and engine assembly pipes, with major customers including SAIC Volkswagen, FAW Volkswagen, and other leading joint venture brands, making it a leader in the stamped parts joint venture era.

What is going on? How did Huada Technology experience three limit downs in a week?

In terms of news, on March 17, Huada Technology announced that its shareholder and director Liu Danqun intends to reduce holdings of no more than 6.15 million shares, accounting for 1.31% of the company’s total share capital and 25% of her holdings in the company.

However, on March 19, the company announced again that based on confidence in the company’s development prospects and recognition of the long-term investment value of the company’s stock, to protect shareholder interests and enhance investor confidence, the shareholder holding more than 5% of the shares and also a director and general manager, Ge Jianghong, plans to increase holdings of the company’s shares within six months using personal or self-raised funds from the date of this announcement.
