Which Chinese stock index reached its 2015 peak just before China’s major stock-market crash?

The Shanghai Composite reached its 2015 peak just before China’s major stock-market crash.

The index closed at 5,178.19 on June 12, 2015, after a powerful rally that had begun in the previous year. Rising retail participation, margin financing, and expectations of continued economic growth helped drive share prices sharply higher.

The market then reversed. By late August, the Shanghai Composite had lost about 40 percent from its June peak, contributing to worldwide financial anxiety. International investors watched the decline closely because China had become a major part of the global economy.

The Shanghai Composite tracks shares listed on the Shanghai Stock Exchange. It is not the same as the Shenzhen Component or Hong Kong’s Hang Seng Index, although all three are commonly discussed when describing Chinese and regional market movements.
