Shanghai and Shenzhen markets recovered in mid‑day trading on Wednesday as investors poured money into renewables and battery-related names, leaving most other stocks lagging. The ChiNext (创业板) index led gains, rising 1.74% by the close of the half‑day session, while the Shanghai Composite edged up 0.05% and the Shenzhen Component gained 0.85%. The STAR Market (科创板) diverged, slipping 0.18%.
Turnover expanded as trading reached RMB 1.67 trillion, about RMB 70.2 billion higher than the previous session, underscoring elevated investor activity. Yet the market’s internals painted a more mixed picture: more than 3,200 listed stocks declined, a sign that the rally was concentrated in a handful of thematic sectors rather than broad‑based.
The strongest momentum was concentrated in “green power” and energy‑storage themes. Green power names staged a breakout, with 绿发电力 posting a second consecutive limit‑up and 节能风电 hitting its daily limit. Energy‑storage plays also led the market, as 正泰电源 completed a re‑rally to the limit and 阳光电源 jumped more than 10%. Battery‑chain components drew fresh attention too: lithium miner 威领股份 logged its second limit‑up in four trading days.
Chemicals showed a cyclical rebound with several stocks hitting limits, while capital‑intensive equipment plays tied to gas turbines lagged; companies associated with that theme, including 杰瑞股份, 图南股份 and 海联讯, all fell. The pattern — a narrow advance led by clean‑energy and battery suppliers alongside broad weakness elsewhere — highlights a pronounced sector rotation.
This intraday action matters beyond mere daily moves. China’s policy push for decarbonisation, expansion of renewable capacity and electrification of transport has created structural demand for power‑grid upgrades, inverters, storage systems and battery minerals. Those long‑term trends are drawing fast, often speculative, capital into listed names perceived to be direct beneficiaries.
At the same time, the market’s concentration raises classic concerns: elevated turnover and clustered gains can presage volatile reversals if policy signals shift or commodity prices move unfavourably. Valuation pressure in the favoured pockets is increasing, and the bulk of listed companies are not participating in the rally, leaving the market vulnerable to disappointing macro data or regulatory headlines.
Looking ahead, investors will watch for confirmation of the rotation over several sessions, any government or regulator comments on subsidies and grid‑connection rules, and movements in global commodity prices — especially lithium and other battery materials. For now, China’s equity market is reflecting a tug‑of‑war between structural, policy‑driven narratives and the short‑term dynamics of speculative flows.
