The GTEX is a broad-based, free-float, market-capitalization-weighted composite index of highly capitalized and actively traded stocks listed on the board of the GreTai Securities Market, a non-profit organization modeled after the NASDAQ. The GTEX index provides a performance benchmark for the Taiwanese over-the-counter securities market. As of September 12, 2011, the total adjusted market capitalization of the GTEX was approximately US $52 billion.
