Aimed at providing investors in China and around the world with an accurate tool for tracking equity performance in China’s growing stock markets, the Dow-China Indexes are constructed with the same strict standards used to develop the Dow Jones Global Indexes.

Float-adjusted shares, which exclude all state-owned shares and unlisted employee shares, are used for stock selection and index calculation, in order to provide an accurate representation of the shares that are actually available to investors for trading. Dow Jones Indexes excludes block holdings of individuals, other companies or governments that exceed 5% of total market value in calculating free-float for selection of component stocks.

The Dow-China Indexes were launched May 27, 1996. Dow Jones & Company, a world-wide provider of business information, launched the Dow-China Indexes to commemorate the 100th anniversary of the world’s most widely reported market indicator, the Dow Jones Industrial Average, which was launched in 1896. All four indexes in the Dow-China Index series have a base value of 100 on Dec. 31, 1993.
