ETFs Definition of 'Exchange-Traded Fund (ETF)' An ETF, or exchange traded fund, is a marketable security that tracks an index, a commodity, bonds, or a basket of assets like an index fund. Unlike mutual funds, an ETF trades like a common stock on a stock exchange. ETFs experience price changes throughout the day as they are bought and sold. ETFs typically have higher daily liquidity and lower fees than mutual fund shares, making them an attractive alternative for individual investors. Because it trades like a stock, an ETF does not have its net asset value (NAV) calculated once at the end of every day like a mutual fund does. Breaking Down 'Exchange-Traded Fund (ETF)' An ETF is a type of fund which owns the underlying assets (shares of stock, bonds, oil futures, gold bars, foreign currency, etc.) and divides ownership of those assets into shares. Shareholders do not directly own or have any direct claim to the underlying investments in the fund; rather they indirectly own these assets. ETF shareholders are entitled to a proportion of the profits, such as earned interest or dividends paid, and they may get a residual value in case the fund is liquidated. The ownership of the fund can easily be bought, sold or transferred in much the same was as shares of stock, since ETF shares are traded on public stock exchanges. Advantages of ETFs By owning an ETF, investors get the diversification of an index fund as well as the ability to sell short, buy on margin and purchase as little as one share (there are no minimum deposit requirements). Another advantage is that the expense ratios for most ETFs are significantly lower than those of the average mutual fund. When buying and selling ETFs, an investor would typically have to pay the same commission to your broker that you'd pay on any regular order, but at COPIA, all your transaction costs are included in your advisory fee. There exists potential for favorable taxation on cash flows generated by the ETF, since capital gains from sales inside the fund are not passed through to shareholders as they commonly are with mutual funds.
