Exchange-traded funds, or ETF’s, have taken the investment world by storm over the last few years. The first ETF, commonly known as the Spider (SPDR), was formed in 1993. This particular ETF tracks the S&P 500, and it is still one of the most widely held ETF’s. The ETF has basically emerged as an alternative to the mutual fund. There are many similarities between an ETF and an index fund, but there are also some key differences. Let’s take a closer look at exactly what an ETF is and why it has become so popular with investors.

An ETF is a security that tracks a particular group of assets. Some ETF’s track a stock index, but some also track areas such as commodities or bonds. While the majority of ETF’s are index related, the SEC did authorize the creation of actively managed ETF’s in 2008, and some investors are starting to go in that direction. For most investors, the single biggest perk to an ETF is the ability to buy or sell it at anytime throughout the day with a stock broker. This is in stark contrast to a mutual fund, which simply has its Net Asset Value calculated at the close of trading each day.

If there is one word that accurately describes an ETF it is flexibility. If you are an investor and are considering purchasing an ETF, you should realize that an ETF can be used in many different ways. Some like to use an ETF as a long-term investment, which is very practical. The upside to this is you are getting the benefits of a mutual fund without the high expense ratios, and with the ability to liquidate your position at any time. Other investors like to use an ETF to actively trade, which can be very profitable as well if you know what you are doing. The flexibility of the ETF allows an investor to sell short, use limit orders, and most ETF’s now offer the capability to buy and sell options. Clearly, the ways to utilize an ETF are unlimited, which gives the investor all the control!
