An exchange-traded fund is an investment fund traded on stock exchanges, much like stocks. An ETF holds assets such as stocks, commodities, or bonds and generally operates with an arbitrage mechanism designed to keep it trading close to its net asset value, although deviations can occasionally occur. Most ETFs track an index, such as a stock index or bond index. ETFs may be attractive as investments because of their low costs, tax efficiency, and stock-like features.
THE VALUE OF INVESTMENTS AND THE INCOME FROM THEM MAY GO DOWN. YOU MAY NOT GET BACK THE ORIGINAL AMOUNT INVESTED.
