Index fund definition
An “ index investment company ” is a type of investment fund that mirrors the operation of a market index, such as the S & P 500.

For case, the S & P 500 grocery store index measures the performance of approximately 500 large-capitalization companies in the U.S. You ca n’t invest in a specific market index itself, but you can invest in an index fund that tracks it. Your index investment company will likely perform very closely to how the index itself performs.

How index funds work

Since there is person doing the work of choosing these investments, the management fees for actively-managed investments tend to be higher. many reciprocal funds use active voice management strategies. passive voice management, on the other hand, is a scheme where a fund coach builds a portfolio of investments that reflect an existing index, such as the S & P 500. This way, the performance of the index store normally closely mirrors that of the index, no hands-on management necessary.
