Why Your Portfolio Is Probably Trailing “The Market”

Why Your Portfolio Is Probably Trailing “The Market”

 “U.S. Stocks Close at Records” was the headline of a front-page article in a recent edition of the Wall Street Journal. As a result of strong recent results, the S&P 500 Index, a widely-followed index that tracks the performance of large-cap U.S. stocks was up more than 10% year to date through September 30. Over the last 12 months, the index was up nearly 18%, according to data from Ycharts.

Many investors with of all stripes with varying objectives and risk tolerances may have examined a recent account statement or checked their balance online and noticed that their portfolio hasn’t fared quite so impressively. In this brief commentary, we offer our thoughts as to why this may be the case.

The short answer is that most investors hold balanced, globally diversified portfolios. What this means is that they, by definition, hold assets other than just U.S. large cap stocks. In an environment in which U.S. large-cap stocks have outperformed most all other major asset classes that comprise a typical globally-diversified, balanced investor’s portfolio, every dollar or percentage point of portfolio assets allocated to something other than U.S. large-cap stocks has hampered performance relative to a portfolio entirely comprised of these stocks over the last year. For many investors that we work with, we see three potential primary contributors to a portfolio’s underperformance relative to the S&P 500 over the last year.

Potential contributor #1: Investors typically own some bonds to provide ballast in their portfolio and to dampen the volatility of stocks. While stocks are typically held to play the role of “return generator” in a portfolio, high-quality investment-grade bonds are sought after to play the role of “risk manager.” The appropriate mix of stocks and bonds in a portfolio is investor-specific and is driven by each investor’s unique objectives, spending needs, time horizon and willingness to bear risk. Investors with high spending needs, a short time horizon and who are unable or unwilling to tolerate substantial volatility in their portfolio will generally hold a portfolio more heavily allocated to bonds, while those with the opposite traits will generally hold a higher allocation to stocks. As you can see in Exhibit 1, bonds have significantly trailed stocks year to date and over the last year.

Potential contributor #2: Many investors diversify their stock holdings beyond U.S. borders by holding international stocks. Global diversification across geographies broadens the investment horizon and positions the portfolio to capture returns wherever they may occur. While in hindsight, we are easily able to ex-post or after the fact observe that U.S. stocks outperformed their international peers over the last year, what’s often forgotten or otherwise not appreciated is that we did not (and neither did anyone else) know that would be the case ex-ante, or prior to the fact. This is ultimately the crux of the case for international diversification. Absent possessing a crystal ball that will reveal ex-ante whether U.S. or foreign stocks will outperform, the best we can do is to diversify so as to ensure we capture some of the strong returns wherever they ultimately occur. Over the long-run, diversification works to smooth out the volatility of the ride by making the highs a bit less high and the lows a bit less low. Depending on an investor’s unique situation, we generally recommend investors allocate 30% or more of their stock holdings to international stocks absent any other investor-specific considerations. As you can see in Exhibit 2, foreign developed market and emerging market stocks have significantly trailed the S&P 500 over the last year.


Potential contributor #3: Many investors may “tilt” their portfolio to overweight value stocks relative to broad stock market indexes. A large body of evidence shows that value stocks (i.e., those trading at a low price relative to some fundamental measure such as book value of equity or earnings) have historically outperformed their growth stock counterparts and by extension the broad market averages not just in U.S. markets but in many other markets around the globe.[1] Like all other successful strategies, the value investing approach goes through periods of underperformance where value stocks trail the broader market. While such periods are unfortunate and can be difficult to live through, we view them to be necessary and integral to the potential long-term success of the strategy. Without the uncertainty associated the potential for periodic underperformance we believe we are unlikely to see persistent differences in expected return over the long run. As Exhibit 3 demonstrates, U.S. value stocks have notably trailed the S&P 500 over the last year.
