Exchange-Traded Fund

A security that represents all the stocks on a given exchange. For example, an exchange-traded fund may track the Standard and Poor's 500. The organization issuing the exchange-trade fund owns each of the stocks traded on the S&P 500 in approximate ratio to their market capitalization. ETF shares can be bought, sold, short-sold, traded on margin, and generally function as if they were stocks. Investors use exchange-traded funds as a way to easily diversify their portfolios at relatively low cost. See also: SPDR.

Exchange traded fund (ETF). Exchange traded funds (ETFs) resemble open-ended mutual funds but are listed on a stock exchange and trade like stock through a brokerage account.

You buy shares of the fund, which in turn owns a portfolio of stocks, bonds, commodities, or other investment products. You can use traditional stock trading techniques, such as buying long, selling short, and using stop orders, limit orders, and margin purchases.

The ETF doesn't redeem shares you wish to sell, as a mutual fund does. Rather, you sell in the secondary market at a price set by supply and demand. ETF prices change throughout the trading day rather than being set at the end of the trading day, as open-end mutual fund prices are.

Each ETF has a net asset value (NAV), which is determined by the total market capitalization of the securities or other products in the portfolio, plus dividends but minus expenses, divided by the number of shares issued by the fund.

The market price and the NAV are rarely the same, but the differences are typically small for the most widely traded conventional ETFs. That's due to a unique process that allows institutional investors to buy or redeem large blocks of shares at the NAV with in-kind baskets of the fund's securities or other products.

Most ETFs are linked to a market index, which determines the fund's portfolio. While the majority of the indexes are traditional, some are described as fundamental. In those indexes, components of the index are identified on the basis of selective criteria, such as their performance, rather than their market capitalization.

Exchange-Traded Fund (ETF)

What Does Exchange-Traded Fund (ETF) Mean?

A type of closed-end mutual fund that trades like a stock on an exchange; ETFs usually are constructed to track an index, a commodity, or a basket of assets like an index fund. ETFs fluctuate in price during the trading day as they are bought and sold on an exchange just like a stock.

Investopedia explains Exchange-Traded Fund (ETF)

Because it trades like a stock, an ETF does not have its net asset value (NAV) calculated every day the way an open-end mutual fund does. By owning an ETF, an investor gets the diversification of an index fund as well as the ability to sell short, buy on margin, and purchase as little as one share (like a stock). Another advantage is that the expense ratios for most ETFs are lower than those of the average mutual fund. When buying and selling ETFs, one pays a brokerage commission, just as one would for a stock. The most widely recognized ETF is called the Spiders (SPDR), which tracks the S&P 500 index and trades under the symbol SPY.
