China News and Finance, March 25—On the 25th, the three major A-share indexes rose by more than 1%, with the Shanghai Composite Index reclaiming the 3,900-point level.

In terms of the market, sectors such as communications cables and supporting equipment, sports, and military equipment restructuring concepts led the gains across both markets; sectors such as oil and gas extraction, oil and gas extraction and services, and silicon solar-grade materials were among the top decliners.

The green power concept remained active. More than 20 stocks including Huaneng Liaoning Energy, Huaneng Energy, and Shaoneng Co., Ltd. hit the daily limit. The computing power leasing concept strengthened, and multiple stocks including Ourida and Daanwei Technology hit the daily limit. Military industry shares rose strongly, with Great Wall Military Industry delivering a second consecutive daily limit. Oil and gas shares continued to adjust, with Tongyuan Petroleum falling by more than 6%.

The optical communications concept surged, and many stocks including MINGPU Optical Magnetics, Zhaofei Optical Fibers, and Yangtze Optical Communication hit the daily limit. It was learned from China Information and Communication Technology Group’s (China Xinke Group) National Key Laboratory of Optical Communication Technology and Networking that, together with Pengcheng Laboratory and Fujitow Changkang Fiber Technology Co., Ltd., the laboratory achieved important technological results in the field of ultra-high-capacity real-time optical transmission. For the first time, on a 24-core single-mode optical fiber with a length of 10.3 kilometers, it achieved real-time bidirectional transmission capacity of 2.5 petabits per second (Pb/s). This is another key breakthrough by China Xinke in the direction of optical transmission featuring “ultra-high capacity, ultra-high rates, and ultra-long distance.”

By the close, among all traded stocks in the Shanghai and Shenzhen markets, the ratio of stocks rising versus falling was 4,874:560. There were 105 stocks hitting the daily limit in both markets, and 4 hitting the daily limit on the downside.

As for individual stocks, some of today’s daily-limit gainers were: Pingtan Development (10.05%), Great Wall Military Industry (9.99%), Zhongli Group (9.98%), Huaneng Liaoning Energy (10.03%), and Hunan Tianyan (9.95%). Stocks hitting the downside daily limit were: Huada Technology (-10.01%).

The top five stocks by turnover rate were: Shiya Technology, Hongming Electronics, Shouhang Xinneng, Zhongli Group, and Diesen Co., Ltd., at 77.580%, 76.591%, 53.793%, 45.609%, and 40.080%, respectively.

Guangfa Securities said that in the short term, the market may continue to fluctuate repeatedly at current levels in order to digest floating gains and wait for clearer fundamental signals. Investors should stay patient, shift from a broad-based rally mindset to cultivating and deeply developing segmented sectors, and actively seize structural opportunities while controlling overall risk.

Yuekai Securities said that from the long-term perspective, the current market adjustment is more about pressure being concentrated and released rather than a reversal of the trend. It still remains firmly and consistently optimistic about A shares long term. Specifically, it is still recommended to focus on two main lines: first, “HALO” trading targets where the supply-demand situation improves, the price-increase expectations are relatively strong, and earnings are expected to recover—such as non-ferrous metals, power equipment, basic chemicals, oil refining and petrochemicals, and coal industries. Second, domestic independently controllable technologies related to scientific and technological self-reliance and self-strengthening—domestic computing power, artificial intelligence, new energy, energy storage, commercial aerospace, and defense and military industry—and related sectors may remain active repeatedly throughout the year.
