Which index fell from 5,178.19 after China's 2015 stock-market bubble peaked?

The Shanghai Composite fell from 5,178.19 after China's 2015 stock-market bubble peaked.

The Shanghai Composite reached its 2015 closing high of 5,178.19 on June 12, after Chinese equities had surged for roughly a year. The rally was fueled by increased margin borrowing, retail investor enthusiasm, and expectations surrounding economic reforms. Prices then reversed sharply, producing severe turbulence in mainland Chinese markets.

The index lost more than 30% in the weeks after its June peak, despite official efforts to stabilize trading. The Shanghai Composite is often confused with the Shenzhen Composite or the Hang Seng Index. It is a mainland benchmark centered on stocks listed on the Shanghai Stock Exchange, while the Hang Seng tracks major companies listed in Hong Kong.
