China's ChiNext index rises 1% to 3,145.89

The ChiNext index, a benchmark for China's high-growth technology companies, rose 1% to 3,145.89 on September 12, 2025, following a week of market volatility. The uptick comes amidst a surge in margin trading and potential new orders for Boeing from Chinese airlines.

On September 17, the margin trading balance on the Shanghai and Shenzhen stock markets reached a record CNY2.405 trillion (USD337.6 billion), according to data from China Securities Data . This significant increase in leverage has been attributed to a rise in retail investors, with the number of individual investors climbing 0.6% from Sept. 1 to Sept. 7. The surge in margin trading has led to a tug-of-war between bulls and bears, with the Shanghai Composite Index and Shenzhen Component Index closing lower despite reaching new highs earlier in the day.

Analysts remain optimistic about the long-term outlook for the market. Hua Xiaowei, director of the Shanghai Securities Research Institute, noted that sharp adjustments during rapid rallies are normal fluctuations and do not necessarily indicate the end of the upward trend . Zhang Di, chief macro analyst at China Galaxy Securities, also highlighted the attractiveness of value and blue-chip stocks due to stable cash flows and improved interest rate spreads, while noting that pricey technology stocks may face pressure without further easing measures .

The potential new order from Chinese airlines for Boeing, which could be up to 500 jets, has further bolstered market sentiment. This reported deal could end a sales drought that has been hurting Boeing's bottom line since 2017 . The European Union's extension of its review of Boeing's $4.6 billion purchase of Spirit AeroSystems until October 14 has also provided Boeing with much-needed time to modify its acquisition bid .

Boeing shares have seen comfortable returns this year, with a roughly 22% profit on shares held since the start of January. The company's stock has performed unevenly, with some downgrades in March and April due to tariff-related uncertainty, but has seen impressive growth throughout the summer . Most analysts remain bullish on Boeing, with an average rating of buy and price targets around $250.

In conclusion, the ChiNext index's 1% rise on September 12, 2025, reflects a market that is cautiously optimistic amidst record margin trading and potential new orders for Boeing. While market volatility persists, the long-term outlook for the Chinese stock market and Boeing remains positive.
