ETF
An exchange-traded fund (or ETF) is an investment fund traded on stock exchanges, much like stocks.[citation needed] An ETF holds assets such as stocks or bonds and trades at approximately the same price as the net asset value of its underlying assets over the course of the trading day. Most ETFs track an index, such as the S&P 500 or MSCI EAFE. ETFs may be attractive as investments because of their low costs, tax efficiency, and stock-like features.
