Which Shanghai stock index peaked on June 12, 2015, before China’s major market crash?

The Shanghai Composite peaked on June 12, 2015, before China’s major market crash.

The index reached 5,178.19, ending a dramatic rally fueled by easier credit, retail speculation, and strong participation by individual investors. After that peak, Chinese share prices fell rapidly. Authorities responded with measures including trading restrictions, support for large companies, changes to initial-public-offering activity, and efforts to stabilize brokerages and major shareholders.

The Shanghai Composite tracks shares listed on the Shanghai Stock Exchange and includes both A shares and B shares. It is not the same as the Shenzhen Component or the CSI 300, which use different groups of stocks and calculation methods.

The episode is often described as the 2015 Chinese stock-market crash, although the turbulence extended into 2016. The Shanghai Composite lost more than 40% from its June peak to its late-August 2015 low, making the peak date a key reference point for measuring the decline.
