Most of us know the names of global indices, but not all know what they are or understand how an index works. An index not only can be analyzed, but it can also be traded. An Index is a group of companies from the same industry, coming into the market under one name. Indices are sometimes also called indexes, but they mean the same asset.

What is a stock index?

The stock index shows the value of a group of stocks from one sector, country, or region, and it is used to measure the overall performance of the ‘place’ it is coming from. The FTSE100 represents 100 companies from the London Stock Exchange, with the largest market capitalization. The first index was created in May 1896, by Charles Dow. It contained that time 12 most significant companies of the US, and today this index includes the 30 largest companies in the US.
