Which Shanghai stock-market index fell 8.49% on China’s Black Monday in August 2015?

The Shanghai Composite fell 8.49% on China’s Black Monday, August 24, 2015.

The Shanghai Composite is a broad index of shares listed on the Shanghai Stock Exchange. Its 8.49% fall on August 24 was one of the most prominent sessions in the 2015–2016 Chinese stock-market turbulence. The sell-off followed a major decline from the market's June 2015 peak and reflected concerns about economic growth, corporate earnings, market valuations, and the government's attempts to stabilize prices.

The Chinese market downturn affected global confidence and contributed to sharp falls in stock markets elsewhere. It also raised questions about the role of margin financing, government intervention, and the relationship between China's domestic share market and its wider economy.

The Shanghai Composite should not be confused with the Shenzhen Component or the CSI 300. These indexes cover different groups of Chinese shares and can post different daily results. The Hang Seng Index, meanwhile, tracks companies listed in Hong Kong rather than the Shanghai market.
