DEFINITION of 'Index Investing'
A form of passive investing that aims to generate the same rate of return as an underlying market index. Investors that use index investing seek to replicate the performance of a specific index – generally an equity or fixed-income index – by investing in an investment vehicle such as index funds or exchange-traded funds that closely track the performance of these indexes.
BREAKING DOWN 'Index Investing'
Proponents of index investing eschew active investment management because they believe that it is impossible to "beat the market" once trading costs and taxes are taken into account. As index investing is relatively passive, index funds usually have lower management fees and expenses than actively managed funds. Lower trading activity may also result in more favorable taxation for index funds as compared with actively managed funds.
