The ChiNext Index, China’s primary gauge for growth and technology stocks, closed 1.65% higher on June 3, 2026, though it gave back more than half of its intraday gains. The index had soared nearly 4% earlier in the session, reflecting a market defined by extreme volatility and massive liquidity. Trading volume across the Shanghai and Shenzhen exchanges ballooned to 3.13 trillion yuan, a significant increase of 337 billion yuan over the previous session.
Sectoral rotation was the defining feature of the day’s trading. Power and coal utilities remained consistently active, with several regional energy firms hitting the daily 10% limit-up. These traditional sectors were joined by high-growth 'concept' stocks in the semiconductor and optical communication space. The CPO (Co-packaged Optics) sector reached historic highs, driven by expectations of intensified AI infrastructure demand, while chip manufacturers like Huate Gas saw gains as high as 20%.
Despite the positive performance of the headline indices—with the Shanghai Composite and Shenzhen Component ending in the green—the broader market sentiment told a more complex story. More than 3,700 individual stocks finished the day lower. The internet finance sector, which had led previous rallies, underwent a sharp correction, with several major players dropping over 10% as investors locked in profits from recent gains.
The volatility in Chinese domestic markets comes against a backdrop of regional turbulence and shifting commodity landscapes. While Japanese and South Korean markets hit record highs, Southeast Asian markets such as Indonesia faced steep declines. Domestically, the surge in energy stocks was likely bolstered by supply-side concerns following Russia’s sudden ban on aviation kerosene exports, highlighting the sensitivity of Chinese industrial stocks to global geopolitical shifts.
