The China A-share stock market has two exchanges – Shanghai stock exchange (SSE) and Shenzhen stock exchange (SZSE). The SSE is the world’s 5th largest stock market by market capitalization at US$5.5 trillion as of April 2018. The combined market capitalization of the listed companies on the SZSE is US$2.285 trillion. It is the 8th largest stock exchange in the world, and the 4th largest in Asia.

The most important Indices in China A-share are CSI 300, CSI 500 and CSI 800.

  • CSI 300 Index,consists of the 300 largest and most liquid A-share stocks.
  • CSI 500 Index, consists of the largest remaining 500 A-Share stocks after excluding the CSI 300 Index. CSI 500 Index reflects the overall performance of small-mid cap A-shares.
  • CSI 800 Index, consists of all the constituents of the CSI 300 Index and CSI 500 Index.

*K Score coverage excludes companies in the financial services and pharmaceutical industries because the financial report of many companies is too dissimilar from the rest of the market.
