BEIJING -- China's Shenzhen Stock Exchange on Wednesday said that it has launched the SZSE 50 Index, which provides real-time market information.

The new index aims to add to the supply of high-quality indices and meet investor demand for index investment, according to the Shenzhen bourse.

It is expected to enrich the investment targets of high-quality enterprises, channel resources to leading enterprises in key industries, and inject capital liquidity into the real economy.

By the end of September, the total market capitalization of these sample companies totaled 7.6 trillion yuan ($1.06 trillion), data from the bourse shows.
