Which Chinese stock-market index fell more than 8% on Black Monday, August 24, 2015?

The Shanghai Composite fell more than 8% on Black Monday, August 24, 2015.

The index declined 8.49% that day, its largest one-day fall since 2007. The drop occurred during a broader period of Chinese stock-market turbulence that began after a rapid rise in share prices and included concerns about economic growth, corporate earnings, and the effectiveness of government interventions.

The Shanghai Composite tracks shares listed on the Shanghai Stock Exchange and is one of the most widely watched measures of Chinese equities. Its decline affected global sentiment because investors feared that weakness in China could reduce demand for commodities and slow the wider world economy.

This episode should not be confused with the 2015 devaluation of the renminbi or with Hong Kong's separate Hang Seng Index. The two Chinese markets are connected but have different listings, structures, and benchmarks.
