Standard & Poor's, the largest financial index company in the world, announced that it had bought the famous Goldman Sachs Commodity Index (GSCI) from Goldman Sachs Group, and also bought two stock indexes, namely Goldman Sachs Industrial Index (GSSI) and Goldman Sachs Technology Index (GSTI).

GSCI, founded in 1991, is one of the most important indexes in the international commodity market. The funds it tracks are as high as $6 billion, most of which are traded in OTC derivatives. The index covers 24 commodities and is considered as the benchmark index to reflect the investment performance of commodity market at present.

after a short transition period, this index will be renamed as S&P GSCI Commodity Index (S&; PGSCICommodityIndex）。

The most famous S&P index series is the S&P 5 Index, which was compiled in 1957 and calculated by the weighted average method. It is weighted by the number of stocks listed and calculated by the base period. Compared with the Dow Jones Industrial Average, this index has a wide sampling area, strong representativeness, high accuracy and good continuity, and is generally considered as the target of an ideal stock index futures contract.

According to industry experts, at present, institutional investors usually include commodities in their asset portfolios in order to better diversify risks. After S&P obtains GSCI, it will provide investors with additional tools for portfolio and risk management, and at the same time, it will increase the content of S&P index.

the Goldman Sachs industrial index is a diversified index, which broadly represents health care, financial institutions, public utilities, consumer companies and cyclical industries, while the Goldman Sachs technology index is a composite index of American technology stocks, including six technology classification indexes.
