Which Shanghai stock-market index reached its 2015 bubble peak on June 12 before China’s crash?

The Shanghai Composite reached its 2015 bubble peak on June 12 before China’s stock-market crash.

The index closed at 5,166.35 on that date after a dramatic rally that had begun in 2014. The rise was fueled by increased retail participation, margin borrowing, and expectations that economic policy would support equities.

Prices then fell sharply. The Chinese government introduced measures including trading halts, restrictions on some sales, and support purchases in an effort to stabilize the market. The decline also affected international markets through concerns about China’s economy and commodity demand.

The Shanghai Composite tracks shares listed on the Shanghai Stock Exchange. It is different from the Shenzhen Component Index, the CSI 300, and Hong Kong’s Hang Seng Index, although all are used to discuss Chinese or regional markets.
