Which 2015 Chinese stock-market index peaked on June 12 before a major sell-off?

The Shanghai Composite peaked on June 12, 2015, before the major Chinese stock-market sell-off.

The Shanghai Composite reached 5,178.19 points that day after a powerful rally driven by retail participation, margin borrowing and expectations that economic or policy support would continue. The market then fell sharply, and volatility continued into 2016. Authorities responded with measures including trading restrictions, interventions and investigations into market activity.

The turbulence affected global confidence because China was a major engine of world economic growth. Concerns about slowing Chinese activity, excessive leverage and the sustainability of the rally spread to other markets and commodities.

China has several important benchmarks, which can cause confusion. The Shenzhen Component tracks a different exchange, while Hong Kong’s Hang Seng Index is not the same as the mainland Shanghai Composite. The June 12 peak specifically identifies the Shanghai benchmark.
