2 1 Shi Ji Jing Ji Bao Dao·2025-11-06 05:09Core Viewpoint - The storage chip sector in A-shares is experiencing a significant rally, driven by rising prices and strong demand from the AI industry, particularly following SK Hynix's announcement of HBM4 pricing, which exceeds market expectations [1][2]. Group 1: Market Performance - As of November 6, A-share storage chip stocks saw substantial gains, with companies like Yishitong (688733.SH) and Aisen Co. (688486.SZ) rising over 10%, and Demingli (001309.SZ) hitting the daily limit [1]. - The price of HBM4 has been confirmed at approximately $560, a more than 50% increase from the current HBM3E price of around $370, surpassing previous industry expectations [1]. Group 2: Price Trends - The storage chip market is witnessing a comprehensive price increase, with DDR5 spot prices soaring by 25% within a week due to major manufacturers like Samsung halting contract quotes [2]. - Analysts predict that the suspension of DDR5 pricing by major manufacturers could lead to a quarterly price increase of 30%-50% [2]. Group 3: Demand Drivers - The surge in storage chip prices is primarily driven by the rapid growth of the AI industry, which has created a massive demand for storage. One AI server requires eight times more DRAM than a standard server [2]. - Companies like OpenAI have indicated a monthly demand for 900,000 wafers, equivalent to 53% of the current global DRAM monthly production capacity, significantly boosting the server memory market [2]. Group 4: Supply Constraints - Structural adjustments in supply are exacerbating the supply-demand imbalance, as major manufacturers like Samsung and SK Hynix shift production towards HBM and DDR5 while phasing out DDR4 lines, leading to severe shortages in DDR4 memory [3]. - The current shortage and price increases across all four major storage categories are unprecedented in the industry, according to the chairman of Adata [3]. Group 5: Financial Performance - Companies in the storage sector are reporting strong financial results, with Jiangbolong achieving a revenue of 6.539 billion yuan in Q3, a year-on-year increase of 54.60%, and a net profit surge of 1994.42% [3]. - Baiwei Storage reported a revenue of 2.663 billion yuan in Q3, marking a 68.06% year-on-year increase, with net profit rising by 563.77% [3]. Group 6: Future Outlook - The storage industry is entering a new upcycle, driven by the increasing demand for memory capacity in large model training and inference, which will further tighten the supply of HBM and DDR5 memory [3]. - The overall demand for AI is expected to remain strong, with projections indicating a 24% year-on-year increase in capital expenditure by major cloud service providers by 2026, which will boost demand for storage chips [4].
