Are ETFs right for you?

While ETFs offer a number of benefits, the low-cost and myriad investment options available through ETFs can lead investors to make unwise decisions. In addition, not all ETFs are alike. Execution prices and tracking discrepancies can cause unpleasant surprises for investors.

Buying high and selling low

ETFs have two prices, a bid and an ask. Investors should be aware of the spread between the price they will pay for shares (ask) and the price a share could be sold for (bid). In addition, it helps to know the intraday value of the fund when you are ready to execute a trade.

At any given time, the spread on an ETF may be high, and the market price of shares may not correspond to the intraday value of the underlying securities. Those are not good times to transact business. Make sure you know what an ETF’s current intraday value is as well as the market price of the shares before you buy.

Tracking error

ETF managers are supposed to keep their funds’ investment performance in line with the indexes they track. That mission is not as easy as it sounds. There are many ways an ETF can stray from its intended index. That tracking error can be a cost to investors.

Indexes do not hold cash but ETFs do, so a certain amount of tracking error in an ETF is expected. Fund managers generally hold some cash in a fund to pay administrative expenses and management fees. In addition, the timing of dividends is difficult because stocks go ex-dividend one day and pay the dividend on some other day while the indexes’ providers assume the dividend is reinvested on the same day the company went ex-dividend. This is a special problem for ETFs that are organized as unit investment trusts (UITs), which, by law, cannot reinvest dividends in more securities and must hold the cash until a dividend is paid to UIT shareholders. ETFs that are organized as investment companies under the Investment Company Act of 1940 may deviate from the holdings of the index at the discretion of the fund manager. Some indexes hold illiquid securities that the fund manager cannot buy. In that case the fund manager will modify a portfolio by sampling liquid securities from an index that can be purchased. The idea is to create a portfolio that has the look and feel of the index and, it is hoped, perform like the index. Nonetheless, ETF managers who deviate from the securities in an index often see the performance of the fund deviate as well.

Several indexes hold one or two dominant positions that the ETF manager cannot replicate because of SEC restrictions on non-diversified funds. In an effort to create a more diversified sector ETF and avoid the problem of concentrated securities, some companies have targeted indexes that use an equal weighting methodology. Equal weighting solves the problem of concentrated positions, but it creates other problems, including higher portfolio turnover and increased costs.

Exchange-traded products (ETPs) are subject to market volatility and the risks of their underlying securities, which may include the risks associated with investing in smaller companies, foreign securities, commodities, and fixed income investments. Foreign securities are subject to interest rate, currency exchange rate, economic, and political risks, all of which are magnified in emerging markets. ETPs that target a small universe of securities, such as a specific region or market sector, are generally subject to greater market volatility, as well as to the specific risks associated with that sector, region, or other focus. ETPs that use derivatives, leverage, or complex investment strategies are subject to additional risks. The return of an index ETP is usually different from that of the index it tracks because of fees, expenses, and tracking error. An ETP may trade at a premium or discount to its net asset value (NAV) (or indicative value in the case of exchange-traded notes). The degree of liquidity can vary significantly from one ETP to another and losses may be magnified if no liquid market exists for the ETP's shares when attempting to sell them. Each ETP has a unique risk profile, detailed in its prospectus, offering circular, or similar material, which should be considered carefully when making investment decisions.
