Leverage Positions Unwound

Chinese stock traders significantly reduced their leveraged positions last month. This unwinding contributed to a sharp sell-off in technology shares. Margin financing, which allows traders to borrow funds for stock purchases, fell 14% in July. Its outstanding value reached 2.59 trillion yuan (US$383.4 billion) by July 31. This was down from a record 3.01 trillion yuan on June 25, according to Chinese financial data provider Wind. The reduction demonstrates growing caution among investors.

Tech Sell-Off Intensifies

The deleveraging was concentrated on tech-focused boards in Shanghai and Shenzhen. This coincided with a broader cooling of global artificial intelligence (AI) investor enthusiasm. Investors questioned the need for extensive capital spending on data centres and cloud services. This re-evaluation came amid elevated stock valuations and expectations of tighter monetary policy from the US Federal Reserve. These factors collectively pushed traders to reduce their exposure.

Star Market Performance

The tech-heavy Star Market 50 Index bore the brunt, falling 26% in July. This marked its sharpest monthly decline since the index began. Wang Chen, a partner at Xufunds Investment Management in Shanghai, noted that investors exiting leveraged positions largely explains the market's substantial decline. He specifically cited technology and AI stocks. He added that overseas AI stock volatility both prompted and accelerated China's deleveraging.

Implications for Beijing

This substantial deleveraging presents a challenge to Beijing's efforts to stabilise its equity market. The reduction in margin debt shows investors are wary of high valuations, particularly in tech. For Asian investors and businesses, this suggests continued volatility in China's tech sector. Capital flows into these areas may remain subdued. The market's reaction to global sentiment shifts also highlights the interconnectedness of tech valuations.
