The three major A-share indices rose collectively on the first trading day after the holiday. By the close, the Shanghai Composite Index increased by 0.87%, the Shenzhen Component Index rose by 1.36%, the ChiNext Index gained 0.99%, and the Beijing 50 Index was up by 0.37%. The combined trading volume of the Shanghai, Shenzhen, and Beijing markets reached 22,182 billion yuan, an increase of 2,192 billion yuan compared to the previous day, with over 4,000 stocks rising across the three markets.

In terms of sectors and themes, the top gainers included oil and gas exploration and services, precious metals, cultivated diamonds, glyphosate, fertilizers, coal mining and processing, optical fiber, power grid equipment, and port shipping. The biggest declines were seen in film and television cinemas, AI applications, computing power leasing, tourism and hotels, insurance, white liquor, duty-free shops, and brain-computer interfaces.

On the market, geopolitical risks escalated again. The U.S.-Iran game boosted oil prices, leading to a broad rally in the oil and natural gas sectors, with over ten stocks such as Zhongman Petroleum and Intercontinental Oil & Gas hitting the daily limit. The cultivated diamond sector strengthened in the afternoon, with Siford and Wolder hitting the 20% daily limit during trading, as some institutions noted that diamonds perfectly meet the heat dissipation needs of AI chips. International phosphate fertilizer prices broke through $700 per ton, driving continuous gains in the fertilizer sector, with nearly ten stocks like China National Chemical Corporation and Jinchengda hitting the daily limit. Additionally, non-ferrous metals, power grid equipment, and optical fiber concept stocks also surged significantly.

Conversely, the film and television cinema sector experienced a collective plunge, with Light Media hitting the 20% daily limit during trading, and Wanda Film, Hengdian Film, and Shanghai Film also hitting the daily limit. According to data from the National Film Administration, the total box office for the 2026 Spring Festival holiday reached 5.752 billion yuan, with 120 million viewers.

The AI application and computing power leasing sectors showed weakness, with Daily Interactive and People’s Daily Online among the biggest decliners.
