On October 29, 2002, the TWSE Taiwan 50 Index was launched. The first tradable index for the Taiwan stock market was developed by FTSE International Limited and the Taiwan Stock Exchange Corporation (TWSE). It monitors the top 50 firms based on their overall market capitalization.

The FTSE’s free float approach provides the foundation for the index computation. It guarantees that the market capitalization that is accessible for investment is reflected in the index’s weights. The TWSE Taiwan Index Series Advisory Committee is an independent committee that oversees the index. On April 30, 2002, the base value was established at 5,000.
