What exactly is an ETF. ETF stands for exchange traded fund. ETF's consist of a basket of stocks much like the Dow 30, Nasdaq 100, or S & P 500. ETF's have been put together to mirror index like activity in the stocks that comprise it.
ETF's function much like mutual funds in that they consist of stocks in indexes,industries, or sectors of industries. The beauty of these financial products is they can provide you exposure to areas of concentrated risk in a sector or industry over a number of different stocks rather than just one or two. It allows you to enjoy the benefts of a rising or falling market yet in general reduces the overall risk of exposure to an individual security.
ETF's provide some advantages over mutual funds in that they generally have lower expense ratio's than most mutual funds. They are more passively managed which reduces costs and they can be sold during the day which you cannot do with your mutual fund. All mutual fund sales are transacted at the end of the business day and can affect adversely the value of your investment if you are trying to trade it during the day. ETF's can also be sold short which you cannot do with your mutual fund. In other word's a mutual fund constantly exposes you the long side of the market even in a declining market. With an ETF you can sell it short if you think the market or sector that ETF represents is going to decline in price and it can be purchased using margin.
They are a great way to diversify and enjoy the benefits of ownership such as price appreciation and dividend capture.
