You can’t directly invest in an index, but you can invest in the stocks making up the index and you can invest in mutual funds and exchange traded funds (ETFs) that attempt to track the index.

Stocks trade on exchanges run by stock exchange operators like the London Stock Exchange (LSE) and the New York Stock Exchange (NYSE). Sometimes those companies also run stock market indexes. The FTSE 100 (pronounced ‘footsie’), an index of the 100 biggest stocks listed on the LSE, is owned by the LSE.
