CSI 300 Index

The CSI 300 (Chinese: 沪深300) is a capitalization-weighted stock market index designed to replicate the performance of the top 300 stocks traded on the Shanghai Stock Exchange and the Shenzhen Stock Exchange. It has two sub-indexes: the CSI 100 Index and the CSI 200 Index. Over the years, it has been deemed the Chinese counterpart of the S&P 500 index and a better gauge of the Chinese stock market than the more traditional SSE Composite Index.
