Which index fell nearly 43% from its 2015 peak during China’s stock-market crash?

The Shanghai Composite Index fell nearly 43% from its 2015 peak during China’s stock-market crash.

The index reached a five-year high of 5,178.19 on June 12, 2015. It then dropped rapidly as leveraged retail speculation unwound, margin financing became more difficult, and investors questioned the sustainability of earlier gains. By August 2015, the market had suffered a dramatic decline from its peak.

Chinese authorities introduced several measures, including trading restrictions, support for share purchases, and interventions involving listed companies. These actions attempted to stabilize prices but also raised questions about the role of government in the market.

The Shanghai Composite is often confused with the Shenzhen Component Index because both are major Chinese benchmarks. The Shanghai index tracks shares listed on the Shanghai Stock Exchange, including many large state-owned companies. The 2015 episode was not identical to the 2008 global financial crisis: it was primarily a sharp domestic equity-market correction, although it affected international confidence and commodity markets.
