stock market - Stok Market Index

A measuring tool

A stock market index measures a part of the stock market to help investors know the performance on a specific portfolio.   This kind of index is made available to investors via the news or firms that deal with this kind of information specifically. There are different ways that the stock market indexes are classified.

For companies that are fairly large and located throughout the world, then they will be located on the S&P Global 100 or MSCI World. Besides a world index like the S&P Global 100, there are national indices as well, which more specifically present the performance o that nation. Stock market indices may also have various versions, which should also be considered.
