Which market index plunged 8.49% on China’s Black Monday, August 24, 2015?

The Shanghai Composite plunged 8.49 percent on China’s Black Monday, August 24, 2015.

The Shanghai Composite Index tracks shares listed on the Shanghai Stock Exchange. On August 24, 2015, it fell 8.49 percent, while other major markets also suffered heavy losses. The session became known internationally as China’s Black Monday and formed part of a broader Chinese stock-market downturn.

The turmoil followed a dramatic rise in Chinese share prices and a sharp reversal that began in June 2015. Concerns about slowing economic growth, currency policy, market valuations, and the effectiveness of official interventions increased selling pressure. Global markets were affected because investors feared that China’s slowdown could weaken worldwide growth.

The Shanghai Composite is not the same as Hong Kong’s Hang Seng Index or the Shenzhen Component. Those indexes represent different exchanges and groups of listed companies, although all were affected by the wider episode.
