Global Semiconductor Sector Surges, Driving Shanghai Composite Above 4200 Points

On May 11, major A-share indices opened higher collectively, with the Shanghai Composite Index reclaiming the 4200-point level, marking a new high since July 2, 2015. By the close, the Shanghai Composite rose 1.08% to 4225.02 points, the Shenzhen Component Index gained 2.16%, and the ChiNext Index surged 3.5%.

Sector-wise, semiconductor concepts exploded across the board, with memory chip stocks leading the charge. Commercial aerospace also saw repeated activity. On the downside, port and shipping concepts underwent collective adjustments, with stocks like Guohang Ocean Shipping Co., Ltd., China Merchants Energy Shipping Co., Ltd., and China Merchants Nanjing Tanker Corporation declining.

Over 3100 stocks advanced in the broader market, marking the fourth consecutive day with more than a hundred stocks hitting their daily limit-up. The combined turnover on the Shanghai and Shenzhen exchanges reached 3.54 trillion yuan, exceeding the 3 trillion yuan mark for the fourth straight session and representing an increase of 490.3 billion yuan from the previous trading day.

After more than a decade, the Shanghai Composite Index finally closed firmly above 4200 points.

While many anticipated a strong performance over the weekend, the market's vigor today still exceeded expectations. First, the index's immediate sprint to 4200 points at the open demonstrated a rare decisiveness, significantly boosting confidence among cautious investors and laying a solid foundation for continued strength. Second, the substantial 490-billion-yuan increase in turnover, especially on a base already exceeding 3 trillion yuan, surpassed most market forecasts. Finally, a rapid midday pullback raised concerns of a potential "fade from highs" scenario. However, the Shanghai Composite withstood the test, further indicating strong support at the 4200-point level. Once this support was confirmed, subsequent capital flows unanimously favored continued buying, allowing the indices to maintain their upward momentum.

Having outlined the broader market, the focus now shifts to the day's biggest hotspot: the semiconductor industry chain. It can be said that capital's choice to target semiconductors as Monday's breakthrough point was significantly guided by the global semiconductor sector's initial surge. Last Friday (U.S. Eastern Time), U.S. chip stocks staged an epic rally, with the Philadelphia Semiconductor Index soaring over 5%, expanding its year-to-date gain to 66.25%. In the early hours of May 11 (Beijing Time), following the opening of the South Korean market, shares of memory chip giants SK Hynix Inc. and Samsung Electronics Co., Ltd. skyrocketed, both hitting record highs. This propelled the KOSPI index to surge 4.26%, also reaching a new all-time high. Japanese equities followed suit, with the Nikkei 225 rising 1.02% and shares of Japanese memory giant Kioxia Holdings Corporation jumping over 11%.

Against this backdrop, semiconductor sectors in A-shares and Hong Kong stocks opened sharply higher today. The A-share chip index surged over 3% in early trading. By the close, Changchuan Technology hit its 20% limit-up, Montage Technology surged 18.52%, and Jiangbolong gained 15.97%.

The memory chip market has recently welcomed multiple positive catalysts. In early trading today, South Korea's SK Hynix Inc. surged 12%, once again刷新历史新高, with its market capitalization breaking through the $900 billion mark. Samsung Electronics Co., Ltd. also saw its shares rise over 7%,同样刷新历史新高. Analysis points to a severe supply-demand imbalance as the core driver behind this surge in memory chip stocks. Since the outbreak of conflict in the Middle East in late February, spot prices for DRAM and NAND flash chips have risen approximately 25% and 18%, respectively. Factors contributing to the supply crunch include: South Korean manufacturers accounting for over 60% of global memory chip supply, with Middle East conflicts disrupting maritime logistics and increasing insurance costs, affecting shipments; AI server demand for High Bandwidth Memory (HBM) is consuming significant capacity, squeezing supply for traditional PCs and smartphones; major manufacturers cut capital expenditure over the past two years, limiting their ability to quickly ramp up production in response to growing demand.

Regarding the price uptrend for memory chips, Goldman Sachs recently raised its 2026 DRAM price increase forecast from about 150% to a range of 250%-280%, and its NAND price increase forecast from about 100% to a range of 200%-250%. UBS has called for a "memory super-cycle not seen in nearly thirty years," noting that AI-driven HBM demand continues to encroach on traditional DDR capacity. Coupled with the concurrent爆发 of server replacement cycles and SSD demand, the global DRAM market's supply-demand gap is expected to persist until the fourth quarter of 2027.

Beyond the comprehensive爆发 of the semiconductor industry chain, several other leading sectors played crucial supporting roles in today's record-high turnover and index gains. (1) Commercial Aerospace The commercial aerospace板块 achieved its sixth consecutive gain. Electric Power Science and Technology Blue Sky Co., Ltd. surged 7.6%, with its stock price续创历史新高. *ST Hangkongtu gained over 14%. Junda Automobile Fittings Co., Ltd. secured its second consecutive limit-up, LandOcean Energy Services Co., Ltd. rose over 12%, while stocks like AVIC Jonhon Optronic Technology Co., Ltd. and China Information and Communications Technologies Group Corporation Limited followed higher.

On May 11, the Tianzhou-10 cargo spacecraft was successfully launched from the Wenchang Space Launch Site in Hainan. The Tianzhou-10 will also carry flexible encapsulated monocrystalline silicon solar cell samples into space for in-orbit space environment experiments. This project aims to provide technical support for China's commercial space internet constellation deployment, space computing power, and the future development of the space photovoltaic industry. Additionally, the second Aerospace Information Technology Conference was held in Tongxiang, Zhejiang, from May 9 to 10. With the theme "Tongxiang's Aerospace Aspirations, Symbiosis of Stars and Clouds," the conference focused on cutting-edge technologies and industrial integration in the aerospace information field, with the commercial aerospace sector being one of the core议题.

(2) Rare Earth Permanent Magnets The rare earth permanent magnet concept fluctuated higher. China Rare Earth Resources and Technology Co., Ltd. hit the limit-up, followed by gains in China Rare Earth Group Co., Ltd., China Northern Rare Earth (Group) High-Tech Co., Ltd., Jiuling Technology Co., Ltd., Baotou Steel Union Co., Ltd., and Zhongke Magnetic Industry Co., Ltd..

On the news front, customs data showed China's rare earth exports in April reached 5,308.6 metric tons, a year-on-year increase of 10.9%. Policy-wise, the "Regulations for the Implementation of the Mineral Resources Law of the People's Republic of China (Draft)" was reviewed and passed by the State Council executive meeting on May 9. Analysis suggests this represents a supply-side reform in key mineral sectors like rare earths. The strategic importance of China's resources like rare earths, tungsten, antimony, gallium, and germanium is becoming more prominent, potentially moving beyond simple supply-demand dynamics, with strategic scarcity premiums expected to be increasingly reflected in prices. Furthermore, recent expectations for Sino-U.S. consultations on rare earth issues have strengthened,明显升温 market attention on the rare earth sector. Currently, China's rare earth industry holds 69% of global smelting and separation capacity and over 90% of refining and processing capacity. In the medium term, China's dominant position in the global rare earth trade landscape is likely to persist.

(3) Computing-Power Synergy On Monday, the computing-power synergy concept maintained its strength. Datang International Power Generation Co., Ltd. recorded its fourth consecutive limit-up, closing at 6.09 yuan per share. Guiguan Electric Power Co., Ltd. and Gansu Energy Chemical Co., Ltd. both hit their limit-up. Stocks like Huadian Liaoneng, Jinkai New Energy Co., Ltd., Huadian Energy Co., Ltd., Yuneng Holdings Co., Ltd., and Huaneng Huayin Electric Power Co., Ltd. followed higher.

After the market close last Friday, four government departments jointly released the "Action Plan for Promoting the Mutual Empowerment of Artificial Intelligence and Energy." The plan aims to推动协同布局 of computing facilities and regions rich in new energy resources, promoting the local consumption of green electricity. Within the power sector, companies involved in direct green power supply to computing parks stand to benefit significantly. The accelerated large-scale application of artificial intelligence is rapidly driving a surge in electricity负荷 for computing facilities. Supported by both政策与行业双重利好, the multi-departmental plan推动AI与能源双向赋能, aiming to foster a良性格局 where "energy supports AI development, and AI empowers energy transition." Coupled with the红利 of dual-carbon goals and the ongoing推进 of measures like nuclear power mechanism pricing, "direct green power connections," and "computing-power synergy," the industry's supply-demand structure continues to improve.
