A stock exchange index is a statistical measure of changes in the securities markets. An index represents a portfolio of securities traded on the marketplace that’s regarded as reasonably representative of the marketplace as a whole. Each index has its own method of calculation. It’s usually expressed as a change in the base value. For a better understanding of the stock exchange, an index ought to be read not in its absolute numerical value but in the percent change in its numerical value. An individual can’t invest in an index directly. But you can invest in index related mutual funds.
