A-shares midday review: Shenzhen Component Index and ChiNext Index both rose over 1% in the morning session, with green power and computing hardware sectors experiencing a collective surge.

China’s A-share three major indexes rose across the board in the morning session. By midday, the Shanghai Composite Index was up 0.88%, the Shenzhen Component Index was up 1.37%, the ChiNext Index was up 1.26%, and the Beijing Enterprises Index 50 was up 1.04%. In the first half of the session, the combined trading value of the three markets—Shanghai, Shenzhen, and Beijing—reached 14752 billion yuan, increasing by 1507 billion yuan versus the previous day. Across the market, more than 4500 individual stocks advanced.

On sectors and themes, power, fiber optics, tourism and hotels, precious metals, computing power leasing, copper-cable high-speed connectivity, CPO, education, airport and shipping, and the sports industry led in gains. Oil and gas extraction and services, photovoltaic equipment, and baijiu stocks lagged relatively. On the trading screen, concept stocks tied to “computing-and-power coordination” continued to surge. Huadian Liaoning achieved an 8-day consecutive limit-up, while more than 10 stocks—including Jinco Power, Shao Neng Co., and Huadian Energy—hit limit-up.

A spike in bidding prices triggered a fiber-optic reversal; related stocks climbed in tandem. Changfei Optics hit the limit-up at one point during the day, while Changguang Huaxin and Fiberhome Communications led in gains. China’s average daily Token calls exceeded 140 trillion. The computing power leasing sector directly benefited, with Oriented and Liting Electronics both registering limit-up, and Huanxin New Network, Founder (East) Communications, and Wangsu Technology leading the way. In addition, multiple sectors such as CPO, precious metals, and education also moved higher.

On the other hand, the oil and natural gas sector followed the decline in international oil prices. Tongyuan Oil, Intercontinental Oil and Gas, and CNOOC all fell.
