Understanding Exchange-Traded Funds (ETFs)
What is an ETF?
An Exchange-Traded Fund (ETF) is an investment fund that trades on stock exchanges, much like stocks. ETFs hold multiple underlying assets, rather than only one like a stock does. They can contain various investments, including stocks, bonds, commodities, or a mixture of investment types. ETFs offer the best attributes of two popular investment vehicles: the diversification benefits of mutual funds plus the trading flexibility of stocks.
