ETF Evaluation: Looking Under the Hood

Understanding how an ETF is constructed can provide a clearer picture of its exposure. A good place to start is by looking at an ETF’s holdings and the security inclusion process for the index it tracks. A detailed look at the underlying holdings can help investors understand if the fund suits their needs. For example, if an investor is seeking targeted exposure to a specific sector, looking into whether an ETF holds large multinational conglomerates that are involved in a broad array of businesses may factor into whether or not the ETF is the best fit.

To learn more about an ETF’s portfolio construction, investors also should examine two critical attributes: the security inclusion rules of the underlying index,¹ which govern what securities the fund should hold; and the fund’s allocations to the selected securities. In particular, it is important to take a closer look at the degree to which the underlying holdings are concentrated or diversified; both approaches have benefits and drawbacks depending on an individual’s risk tolerance and investment goals.

Tracking the Competition

Evaluating an ETF’s performance can include looking at the fund’s performance both on its own and in comparison to peers or an underlying index. Performance over time can provide valuable insights into how the fund has fared under different market conditions. Assessing performance against its peers can provide insights into how similar investments with relatively small differences in security selection processes, exposures, or allocations may react to changes in the market.

Performance can also be measured against its underlying index. Total return difference is a measure of how closely an ETF performs relative to its index. Many factors can influence an ETF’s total return difference, such as the normal operation of a fund, the liquidity of an ETF’s underlying holdings, or a foreign market’s trading hours. For example, a discrepancy may develop between the index returns and the ETF’s net asset value (NAV) if a U.S.-traded ETF holds securities that are traded overseas and one market is open while others are closed.

Evaluating an ETF’s performance can include looking at the fund’s performance both on its own and in comparison to peers or an underlying index.

A small total return difference that is close to the expense ratio is normal, while a large difference beyond that may warrant further investigation. However, keep in mind that total return difference can vary widely from one type of ETF to another. For example, U.S. equity ETFs generally track their indexes relatively tightly, while international ETFs and fixed income ETFs can experience higher tracking discrepancies due to a variety of factors.

ETF Expenses: What It All Costs

The total cost of owning an ETF encompasses:

Fund expenses. Also known as the ETF's expense ratio, is often the only explicit cost investors are able to compare, and can sometimes assume an outsized importance when evaluating ETFs. While low fund expenses can seem like an obvious plus, it is important to remain aware of the kind of performance or exposure that accompanies the low fee. For example, an ultra-low-cost ETF that cannot deliver solid performance or the desired exposure may not be the best choice.

Trading costs.  These can include commissions, liquidity, and bid-ask spreads.²

• Commissions are the fees investors pay to buy or sell ETFs—these vary widely depending on the individual brokerage, with some offering commission-free trading for select ETFs. 
• The liquidity of the underlying holdings also has a large influence on trading costs, because some securities are more liquid than others. For example, an ETF that holds a basket of extremely liquid large-cap domestic companies will typically have lower bid-ask spreads, and therefore tends to be easier to trade in a cost-effective manner. On the other hand, an ETF that deals in more difficult-to-trade securities such as thinly-traded bonds or foreign equities will tend to experience higher bid-ask spreads and elevated trading costs, which may impact ETF returns.

Portfolio turnover and rebalancing.³ To remain in line with their respective indexes and ensure their underlying securities are held in the correct proportions, ETFs must periodically rebalance their holdings.⁴ The more frequently they rebalance, the higher the portfolio turnover. ETFs with higher portfolio turnover may incur elevated trading costs on the underlying securities, which can detract from returns.

Capital gains. Although ETFs are known for their tax efficiency, some types may still generate tax liabilities for shareholders in the course of their operations. The fund provider’s website should specify whether the ETF has made taxable distributions, and if so, how much.

Key Takeaways

Evaluating ETFs is a critical skill for ETF investors. By taking a closer look at how an ETF delivers exposure and taking the time to understand performance, underlying holdings, and ownership costs, you should be well-equipped to choose the right ETF for your needs.
