A-share review | Index differentiation, Science and Innovation 50 fell more than 5%, nuclear power grids bucked the trend and strengthened, semiconductor memory chips continued to adjust
The Zhitong Finance App learned that on August 3, the three major A-share indices collectively closed down. The yellow and white lines were clearly divided, and the overall performance of small and medium capitalization stocks was better than that of large-cap weighted stocks. At the close, the Shanghai Stock Exchange Index fell 0.59% to 3809.66 points, the Shenzhen Securities Index fell 0.96% to 13448.29 points, the GEM index fell 1.24% to 3302.55 points, the Science and Technology Innovation 50 Index fell 5.08% to 1552.89 points, and the Beijing Stock Exchange 50 fell 0.66% to 1076.07 points. The Shanghai and Shenzhen markets traded 386 million yuan throughout the day in 1997, down 544.562 billion yuan from the previous trading day. In the entire market, 4005 stocks rose, 1,466 fell, 83 rose or stopped, and 9 fell to a halt, accounting for about 72% of the increase. In terms of sectors, controlled nuclear fusion/nuclear power, power grid equipment, wind power equipment, motors, paper making, photovoltaic equipment, and planting industries registered the highest gains; sectors such as glass glass fiber, semiconductors, electronic chemicals, storage chips, lithography machines, and coal mining registered the highest declines.
driving factors
On the same day, the market showed structural differentiation with “weak indices and strong individual stocks”. The decline in major indices was dragged down by technology sectors with large market capitalization such as semiconductors, while most small and medium capitalization stocks recorded increases. The nuclear power/controlled nuclear fusion sector has exploded across the board, and many stocks such as Jiusheng Electric, Libert, Heduang Intelligence, Fusion Nuclear Power, and China Nuclear Construction have risen and stopped. The catalyst came from the decision of the Executive Meeting of the State Council on July 31 to approve a total of 8 new units for four nuclear power projects, with a total investment of over 170 billion yuan. The power equipment industry chain such as grid equipment, wind power, and motors strengthened simultaneously, and all sectors increased by more than 2.5%.
The AI application platform rebounded, with 6 connected boards for smart education, 2 connected boards for Tianyu Mathematics and Hengyin Technology. The official DeepSEEK-v4-Flash API began public testing on July 31, and the National Supercomputing Internet launched the model call and download service on August 2.
The semiconductor industry chain continued to be adjusted. Science and Innovation 50 fell 5.08%, GigaYi Innovation fell to a standstill, leading electronics fell to a halt. Changchuan Technology fell 12.41%, Precision Electronics fell 12.57%, Core Source fell slightly by 11.04%, and Tuojing Technology fell more than 10%. Korea's KOSPI closed down 5.13% on the same day, Samsung Electronics and SK Hynix both fell nearly 9%, and the overseas semiconductor sector weakened simultaneously.
The glass and glass fiber sector fell 7.17%; China's Jushi fell to a halt; the electronic chemicals sector, Honghe Technology, fell to a halt.
Popular sector aspects
1. Nuclear power/controlled nuclear fusion: The sector exploded across the board, and more than 10 stocks including Jiusheng Electric, Libert, Heduang Intelligence, Nuclear Power Finance, and China Nuclear Construction rose and stopped. On July 31, the executive meeting of the State Council decided to approve four nuclear power projects: Zhuanghe Phase I, Zhejiang Jinqimen Phase II, Guangdong Taipingling Phase III, and Shandong Laiyang Phase I, with a total investment of over 170 billion yuan. The nuclear power equipment industry chain was directly catalyzed.
2. Power grid equipment/electricity: The power grid equipment sector rose 2.68%, and many stocks such as Jiusheng Electric, Baili Electric, and Great Wall Electric rose and stopped. The power sector rose 1.11%, while Shennan Electric Power A, Huadian Lioneng, and Leshan Electric Power rose and stopped. The power equipment industry chain linkage expectations brought about by continued progress in the construction of new power grids and centralized approval of nuclear power projects provide support for related sectors.
3. AI application: Chuanzhi Education has 6 consecutive boards, Tianyu Mathematics and Hengyin Technology have 2 consecutive boards, and Jihong Co., Ltd. has risen and stopped. The official DeepSeek-V4-Flash API began public testing on July 31. The National Supercomputing Internet launched a model call and download service on August 2; the photovoltaic equipment sector rose 1.81%, Tongwei shares, Follett, and Guosheng Technology rose and stopped, and the General Administration of Market Regulation launched price compliance guidance for the photovoltaic industry on July 31 to boost the sector.
Adjust the section
The semiconductor sector fell 5.84%, with the largest decline in the direction of memory chips. Zhaoyi Innovation fell to 340.74 yuan, with turnover exceeding 23 billion yuan; lead base electricity fell to a halt; Changchuan Technology fell 12.41%, Precision Electronics fell 12.57%, Core Source fell slightly by 11.04%, Tuojing Technology fell by more than 10%; Deming Li fell 9.56%. The glass and fiberglass sector fell 7.17%, while China's Jushi fell to a halt. The above directions all had large increases in the previous period, and the decline was the highest on the same day. Overseas, South Korea's KOSPI closed down 5.13% on the same day, while Samsung Electronics and SK Hynix both fell nearly 9%.
