A-shares midday review: The ChiNext Index rose over 3% in the half-day session, hitting a new high for the year, with photovoltaic equipment and CPO concept stocks leading the gains.

The three major A-share indices rose collectively in the morning session. By midday, the Shanghai Composite Index was up 0.16%, the Shenzhen Component Index rose 1.57%, the ChiNext Index gained 3.3%, and the Beijing Stock Exchange 50 Index increased 0.63%. In the first half of the day, the combined trading value across the Shanghai, Shenzhen, and Beijing markets reached 14,539 billion yuan, up 1,391 billion yuan from the previous day. More than 2,100 stocks across the entire market rose.

In terms of sectors and themes, photovoltaic equipment, batteries, energy metals, power, optical fiber, CPO, tourism and hotels, and PET copper foil led the gains; oil and gas exploration and services, Huawei Ascend, data security, computing power leasing, diversified finance, and chemical raw materials were among the biggest decliners.

On the trading screen, driven by the overnight rally in U.S. optical communications stocks, optical module and CPO concept stocks rose across the board. Yuanjie Technology hit a 20cm limit-up and its share price broke through 1,000 yuan, while Xinyisheng and Zhongji Xuchuang surged at the same time. New energy track stocks such as photovoltaics and batteries strengthened during the session, with Chint Power and Shangneng Electric both reaching the daily limit-up. It is reported that Tesla is seeking to purchase photovoltaic manufacturing equipment worth $2.9 billion from Chinese suppliers. Meanwhile, sectors such as power, optical fiber, and tourism and hotels were active.

On the other hand, most oil and gas stocks pulled back, with Zhunyou Shares and Qianeng Hengxin seeing the biggest declines. The computing power leasing sector also retreated; Chaosun Communication hit the daily limit-down, while Dawi Technology and Eastern Guoxin fell as well.
