Which Chinese stock exchange saw the Shanghai Composite plunge during the 2015 Chinese stock-market crash?

The Chinese stock exchange where the Shanghai Composite plunged during the 2015 Chinese stock-market crash was the Shanghai Stock Exchange.

The Shanghai Stock Exchange is one of mainland China’s principal securities markets. A strong rise in Chinese share prices during 2014 and the first half of 2015 attracted many inexperienced retail investors and encouraged borrowing to buy stocks.

The Shanghai Composite reached a 2015 closing high of 5,166.35 on June 12. It then fell sharply as leveraged positions were unwound, economic concerns grew, and confidence in the rally weakened. The government responded with measures including trading restrictions, support for share purchases, and investigations of market activity.

The turbulence spread to other global markets, although its causes and effects differed from those of the 2008 crisis. The Shanghai Composite is an index, while the Shanghai Stock Exchange is the marketplace on which many of its constituent shares trade.
