Storage chip concept surges strongly, Chaoying Electronics hits daily limit, Baivi Storage stock reaches new high

Storage chip concept rebounded strongly again during the trading session on the 25th. As of the latest report, Beiwei Storage rose over 12%, continuing to hit a new all-time high; Shengbang Co., Xiechuang Data, and others gained over 10%, Chaoying Electronics and Sanfu Co. hit the daily limit, Jiangbolong rose nearly 8%, and Demingli increased about 7%, also reaching new highs.

On the evening of the 24th, Beiwei Storage announced that the company signed a routine operational procurement contract with a certain storage manufacturer. The company agreed to purchase a specific type of storage wafer from the supplier according to the contract’s specified quantity, price, and schedule. The total committed purchase amount is $1.5 billion, with a commitment period of 24 months.

The announcement states that, according to the contract, the company’s purchase volume of this product within 12 months accounts for 11.1% of its NAND Flash procurement total in 2025 and 18.01% of its NAND Flash sales total in 2025, both relatively small proportions. The company signed the contract to lock in part of its basic usage for the next 24 months, aligning with its business scale and planning, with overall manageable risks.

According to recent reports from Yonhap News Agency, Samsung Electronics’ union members approved a collective struggle action proposal with a 93.1% approval rate. The union plans to hold a rally on April 23 and conduct an 18-day nationwide strike from May 21 to June 7.

CITIC Securities pointed out that if the strike occurs as scheduled, it could impact Samsung’s chip production lines at the Pyeongtaek Semiconductor Complex in South Korea, affecting the capacity release of DRAM, NAND flash, and HBM chips at the site. Once production lines halt, restarting and re-testing the production chain will be time-consuming and resource-intensive. Since 2026, driven by strong demand for AI, storage chips remain in a tight supply-demand pattern with prices continuously rising. According to Omdia data, Samsung Electronics’ share of the global DRAM market in Q4 2025 is 36.6%, and according to TrendForce data, its share of the global NAND market in Q4 2025 is 28%. The potential risk of production stoppages at Samsung could further exacerbate the global supply tightness of storage chips.

The institution believes that storage price increases and high prosperity are expected to continue throughout 2026. Meanwhile, Samsung’s possible total strike could be an opportunity for domestic major storage manufacturers to expand their market share. In recent years, domestic storage giants have rapidly advanced capacity building and technological breakthroughs. Domestic 3D NAND products achieved mass production of 232-layer flash memory in 2025 and continue to iterate toward higher stacking layers. Domestic DRAM products have achieved mass production of mainstream fourth and fifth-generation DDR4, DDR5, LPDDR4X, LPDDR5/5X, etc. Capacity expansion and technological iteration of domestic storage giants are expected to accelerate during the “14th Five-Year Plan” period, with their global market share likely to continue increasing. Against the backdrop of global shortages of storage products, rising prices and profitability, relatively low domestic market share, and strong domestic industry policy support, the growth potential of core suppliers of materials and components, driven by storage giants’ expansion, is highly certain.
