Major stock indices showed mixed performance, with the Shanghai Composite Index and Shenzhen Component Index experiencing volatile adjustments in the morning session, both falling more than 1% intraday. The combined half-day turnover for the Shanghai and Shenzhen markets reached 1.51 trillion yuan, an increase of 2 billion yuan from the previous trading session. Memory chip concepts defied the broader market decline with a late-morning rally. By the midday break, Langxin Technology surged by the 20% daily limit, while Guoke Microelectronics rose over 10%. Yingxin Development and Taiji Industry also hit the upside limit, and Biwin Storage Technology Co.,Ltd. advanced more than 8%, continuing to set new historical highs. Additionally, Hengshuo Co., Ltd. and Yacon Electronics followed with gains.
Industry developments indicate a new wave of price increases in the semiconductor sector. Reports suggest wafer foundries such as United Microelectronics, Vanguard International Semiconductor, and Powerchip Semiconductor Manufacturing are raising prices. Citing Taiwan's Economic Daily News, financial media reported that following memory chips and packaging, the semiconductor supply chain may see another round of price hikes. Mature process wafer foundries including United Microelectronics, Vanguard, and Powerchip could adjust quotes as early as April, with increases reaching up to 10% or more. United Microelectronics declined to comment on market rumors but previously noted that current pricing conditions are "more favorable than before." Vanguard's price adjustment letter indicated plans to revise foundry prices starting April 2026 but did not disclose the extent of the increase, with the company not responding to inquiries. Powerchip confirmed it has begun raising prices this quarter, primarily adjusting product lines with lower gross margins. Additionally, major customers in mature processes, led by driver IC design houses, are planning price hikes due to rising costs.
Separate reports indicate the global semiconductor industry is preparing for a new round of price increases. Three major international chip design firms—Texas Instruments, NXP Semiconductors, and Infineon Technologies—have recently issued price adjustment notices to customers, announcing increases for some products effective April 1. Among them, certain Texas Instruments products could see hikes of up to 85%. Infineon's mainstream products are expected to rise between 5% and 15%, with some high-end products facing even larger adjustments. Southwest Securities pointed out that explosive demand and rigid supply are driving continuous price increases, with memory entering a super cycle. First, AI model technology is exceeding expectations with iterative upgrades, leading to explosive growth in global token consumption and generating massive demand for data storage, processing, and retrieval, ushering in a super boom cycle for the storage industry. Second, overseas memory manufacturers are shifting limited capacity toward high-margin HBM and DDR5 products, severely squeezing capacity for consumer-grade and low-end memory chips and widening the supply-demand gap. Third, following excessive capacity expansion and capital expenditure in the last cycle, memory manufacturers are acting more cautiously this cycle. Moreover, high-end HBM memory chips face challenges such as long cleanroom construction cycles and difficult yield ramp-ups, keeping short-term supply tight. Against this backdrop of explosive demand and rigid supply, industry forecasts suggest memory prices will continue rising overall through 2026.
Riding the AI wave, China's domestic storage industry chain is rising comprehensively. Against the backdrop of the global storage industry's rapid advancement, domestic storage enterprises are leveraging advantages such as engineering talent dividends, well-developed infrastructure, and comprehensive industrial chain support to rise at an impressive pace. Leading local companies like Yangtze Memory Technologies, ChangXin Memory Technologies, GigaDevice Semiconductor, and Longsys are achieving breakthroughs in AI computing, consumer electronics, and enterprise markets through independent architectural innovation and process iteration, continuous capacity expansion, and steady yield improvements, driving China's storage sector from scale growth to technological leadership. Central China Securities stated that AI is driving strong demand for memory, with the memory cycle continuing its upward trend. AI and domestic innovation demand are expected to significantly benefit domestic storage manufacturers, suggesting attention to investment opportunities in domestic storage module and chip makers. Recently, overseas analog chip manufacturers including Texas Instruments, Analog Devices, and Infineon have issued price hike notices. Analog chips play a critical role in AI system stability, energy efficiency, and scalability, serving key functions in power conversion, voltage regulation, and signal chain management, and playing an important role in the large-scale construction of AI data centers. AI servers are driving substantial increases in demand for power management chips and signal chain chips, while recovering demand in industrial and automotive sectors is aiding the analog chip industry's recovery. Benefiting from the global analog chip industry's recovery and AI demand explosion, domestic analog chip manufacturers are accelerating innovation, suggesting attention to investment opportunities in this segment.
