Core Viewpoint - The global storage chip market has entered an unprecedented price surge since the second half of 2025, driven primarily by the AI computing revolution rather than traditional consumer electronics demand [1][6]. Supply Side Analysis - The supply side is struggling to expand production quickly, with new wafer fabs taking an average of 18-24 months to establish, and stable supply often taking even longer to materialize [1][6]. - Overseas storage manufacturers have adopted production cuts and cautious capital expenditure during the previous downturn, leading to reduced supply elasticity, which causes prices to rise with slight demand fluctuations [1][6]. - Even with domestic manufacturers being more proactive, significant new capacity is unlikely to be reflected in statistics until the second half of 2026 or later [1][6]. Demand Side Analysis - The demand structure is shifting, with AI data centers increasing the priority for HBM, server memory, and enterprise SSDs, leading manufacturers to focus resources on high-margin products, thereby squeezing the supply of general-purpose DRAM and NAND [1][6]. - Downstream entities are pre-locking quantities and stockpiling, further amplifying short-term shortages and price increases [1][6]. Price Trends and Expectations - Compared to 2025, the price increase in storage chips this year is characterized by being more "comprehensive" and with a steeper slope, moving from structural shortages to mainstream DDR5 and client SSDs [2][7]. - The market's imagination regarding NAND/SSD demand is being elevated by AI, with leading companies emphasizing the potential for context storage layers to enhance inference efficiency and GPU utilization [2][7]. Future Outlook and Investment Opportunities - The current market conditions are expected to remain favorable at least until the first half of 2026, with strong upward price expectations for the first and second quarters of 2026 [3][8]. - Key variables include the release pace of new capacity, especially from domestic manufacturers, and the alleviation of advanced packaging/testing bottlenecks related to HBM [3][8]. - Investment opportunities include profit elasticity and product structure upgrades for storage IDM, as well as opportunities in equipment, materials, components, and advanced packaging/testing segments related to capacity expansion and generational upgrades [3][8].

Group 1 - A-shares showed mixed performance on September 18, with the Shanghai Composite Index rising by 0.08%, driven by gains in sectors such as computer hardware, semiconductors, and motorcycles, while basic metals and diversified finance sectors faced declines [1] - The chip technology stocks performed strongly, with the chip ETF (159995) increasing by 3.12%, and notable individual stock performances included Haiguang Information up by 8.04%, Ruixin Micro up by 7.94%, and Longxin Zhongke up by 5.57% [1] - According to TrendForce, NAND Flash wafer prices are expected to rise by 10% to 15% in Q2 2025 due to tightening supply and recovering demand, while client SSD prices are projected to increase by 3% to 8% [3] Group 2 - Micron announced a halt in pricing for all DDR4, DDR5, LPDDR4, and LPDDR5 storage products, with expectations of price increases following a one-week suspension of quotes [3] - As the mobile season and enterprise demand increase in Q4 2025, the storage sector is anticipated to experience a new round of price hikes [3] - The chip ETF (159995) tracks the Guozheng Chip Index, which includes 30 leading companies in the A-share chip industry across various segments such as materials, equipment, design, manufacturing, packaging, and testing [3]
