The Chinese Securities Index (CSI) 300 consists of 300 stock with the highest total market value and liquidity of all the "A" shares listed on the Shanghai and Shenzhen stock exchanges. It is the key index for Chinese stock prices. The Index is calculated using the weighted average method of total market value, a method that includes the adjustment of floating share ratios. The computation sets 31 December 2004 as the base time with a total market value of 1,000, and then the subsequent total market value is indexed.

The continuity of Index is secured by adjusting the total market value in a manner that precludes any influence of paid capital increases, new listing and delisting, which are not considered valid indicators of market conditions.
