The GF Fund SSE Science and Technology Innovation Board 50 ETF (588060) rose over 3%, with the weighted stock SMIC surging over 14% on increased volume, pushing its market value above the trillion yuan mark Against the backdrop of overnight declines in overseas chip stocks, domestic semiconductor stocks continue to surge. The STAR 50 Index rose nearly 4% yesterday and continues to soar today. As of 14:01, the STAR 50 Index, with a semiconductor weight of 73.8%, is up 3.08%, reaching a new historical high; among the major weighted stocks, SMIC is up over 14%, with a market value exceeding one trillion; Tsinghua Unigroup is up over 13%, and Cambrian and Inspur are both up over 3%. Changxin Technology's performance has exceeded expectations, and Yangtze Memory Technologies' IPO is accelerating, with the "capital mobilization" of the domestic storage giants injecting strong momentum into the entire semiconductor sector. On May 19, the China Securities Regulatory Commission disclosed that Yangtze Memory Technologies has completed its IPO counseling filing and is officially targeting the capital market. The fundraising and expansion plans of the two storage giants are expected to translate into certain orders for upstream equipment and materials companies, marking a golden window period for domestic substitution. At the same time, a profound "migration" is occurring in the global semiconductor supply chain. As overseas giants shift their production capacity to the high-profit AI sector, a large number of mature process orders are accelerating their return to China. SMIC recently revealed that its 8-inch production line has been running at full capacity since the second quarter of last year. Due to many overseas memory factories exiting the civilian market, there is a shortage of dedicated NOR Flash and NAND Flash capacity, and this demand is concentrating on domestic manufacturers represented by SMIC. From the breakthrough of the storage giants to the return of mature process orders, China's semiconductor industry is leveraging the AI super cycle to achieve collective leaps in multiple key links of the supply chain. Huayuan Securities pointed out that the global semiconductor supply chain has entered an expansion cycle, and domestic wafer fabs are increasing local support to ensure supply chain security, promoting significant breakthroughs in domestic production in etching, thin film deposition, and other processes, while coating, developing, and measurement processes will also see progress in domestic production. As the expansion of advanced storage and process wafer fabs continues, the self-controlled sector is expected to usher in a new upward cycle, benefiting core equipment, components, materials, and cleanroom fields from this industrial trend.
