Which Chinese stock-market benchmark fell sharply after China’s 2015 market bubble burst?

The Shanghai Composite fell sharply after China’s 2015 stock-market bubble burst.

The Shanghai Composite rose dramatically from mid-2014 into June 2015, helped by margin lending, retail-investor enthusiasm, and expectations surrounding economic reform. It reached 5,178.19 on June 12, 2015. The market then reversed, and the index fell by more than 40 percent over the following months.

Chinese authorities responded with measures including trading suspensions, restrictions on some sales, efforts to support share prices, and investigations into market activity. The turbulence also produced several days of global concern, particularly when Chinese share declines coincided with worries about slowing economic growth and falling commodity prices.

The Shanghai Composite is not the same as Hong Kong’s Hang Seng Index or the Shenzhen Component Index. It tracks shares listed on the Shanghai Stock Exchange, while the other benchmarks represent different markets and groups of companies.
