Exchange-Traded Fund (ETF) is a form of securities that trade on an exchange that contains many types of investments, including stocks, commodities, bonds, or a mixture of investment types. Considered as a marketable security, ETFs are easily bought and sold, offering the best attributes with lower fees and tax-efficiency. A one-size-fits-all solution, ETFs combine the features of a mutual fund, with the intraday trading feature of a closed-end fund. ETFs can be more cost-effective and more liquid than mutual funds, enabling them to have more diversification benefits while also mimicking the ease with which stocks are traded.
