CSI

China Securities Index Co., Ltd. (CSI), known in Chinese as 中证指数有限公司 and commonly shortened to 中证, is a major index provider and benchmark index compiler for China's capital markets. It was established as a joint venture by the Shanghai Stock Exchange and the Shenzhen Stock Exchange, giving it a central role in the construction and maintenance of equity indices that track the performance of listed companies in mainland China. Its official website is csindex.com.cn. CSI's core business is the development, calculation, publication and licensing of indices and benchmarks. These include broad market benchmarks, size and sector indices, strategy and thematic indices, and fixed income indices. Among its best-known products is the CSI 300 Index, which tracks the performance of 300 large and liquid A-share stocks listed on the Shanghai and Shenzhen exchanges and is widely used as a benchmark by asset managers, mutual funds, exchange-traded funds and institutional investors. As an index provider, CSI sits within the financial services and capital markets ecosystem. Its indices serve as the basis for index-tracking products such as ETFs and index funds, as performance benchmarks for portfolio managers, and as underlying references for derivatives and structured products. The company also provides index-related data services and licensing to domestic and international financial institutions. CSI operates primarily in China but its indices are used globally by investors seeking exposure to Chinese equities and bonds. Its ownership by the two main mainland stock exchanges positions it as a quasi-official standard-setter for A-share benchmarks. The company is not listed on a stock exchange itself; it is a private joint venture owned by the exchanges.

China Securities Index Co., Ltd.

Its creation reflected the growth of China's capital markets and the increasing demand for standardized, investable benchmarks that could support index funds, ETFs and derivatives. A central development in CSI's history was the launch of the CSI 300 Index, a large-cap A-share benchmark that became one of the most widely followed indicators of the Chinese equity market. The CSI 300 is calculated by CSI and is used as the underlying index for numerous index funds and ETFs, as well as a performance benchmark for domestic and international asset managers. CSI subsequently expanded its index family to cover mid- and small-cap segments, sectors, themes, strategies and fixed income, building a broad suite of benchmarks.

Its indices are licensed to fund managers, exchanges and financial institutions for the creation of investment products and for benchmarking purposes.
