The Dow Jones China Offshore 50 Index is created by Dow Jones & Company, Inc., first published in October, 2005. It is designed to serve as the basis for index-linked products, particularly exchange-traded funds (ETFs) and derivatives. The index intends to represent the largest stocks of compa¬nies whose primary operations are in mainland China but that trade on exchanges in Hong Kong or the U.S.

The Dow Jones China Offshore 50 Index is constructed by selecting companies from the broad-based Dow Jones China Index with the objective of optimizing the factors of greatest importance in an investable index: liquidity; turnover rate; transaction costs and tracking error against the broad-market benchmark.
