Institutional investors often sell funds (or fire managers) once they have underperformed the market over the last two to three years, typically replacing them with funds or managers that recently outperformed. This seemingly sensible strategy, intended to identify skilled managers, is often bad for future returns. No doubt some of the recently stellar managers have skill, but high alpha is often a result of luck, and the newly expensive holdings typically set the stage for poor future performance. Meanwhile recently disappointing managers often provide exposure to assets, factors, and strategies that have become inexpensive and are positioned for near-term success.
In this article,1 we show that investors should urgently stop relying so heavily on past performance to choose investments. Performance chasing is a reliable path to poor investment results: too often it means that we sell newly cheap and buy newly expensive assets. When we supplement information about past performance with current relative valuation—compared with past norms—our decisions will be far more richly informed. We can determine whether the past performance was merely a consequence of portfolio revaluation, which may be more luck than skill, and we can determine whether the portfolio is now cheap or rich. And, we can predict mutual fund performance with better reliability than past methods.
Last year, in a series of articles, we demonstrated that relative valuations can predict future performance of equity factors and smart beta strategies. We now show that factor valuations can not only forecast factor returns, but can also forecast mutual fund alpha,2 and can provide a powerful tool to select the managers that have better chances of future outperformance. Factors and strategies can get relatively expensive after periods of great performance, and can get relatively cheap after periods of poor performance. When a factor or a strategy is cheap relative to its own history, it tends to perform well, while valuations that are high relative to historical norms predict subsequent underperformance.
The counterintuitive policy of firing recent winners and hiring recent losers, relative to the market, is—demonstrably—a better way to invest than the conventional performance-chasing manager-selection rules that most investors rely on today. Harvey and Liu (2017) demonstrate there is no repeatability in performance, which makes performance chasing in manager selection largely futile. Making matters worse, Cornell, Hsu, and Nanigian (2017) document mean reversion in mutual fund performance. The research we present in this article provides evidence that valuations are a key reason for this mean reversion: underperforming managers tend to hold cheaper assets, with cheaper factor loadings, setting them up for good subsequent performance, whereas recently winning managers tend to hold more-expensive assets. We show that investors can better identify funds likely to outperform in the future if they know 1) the return forecasts estimated for various factors, based on their relative valuations; and 2) the fund’s exposure to these various factors.
In institutional investing, standard procedure is to terminate managers and funds after about three years of underperformance. Retail investors and their broker/advisors are frequently even less patient. Often in evaluating past manager performance, investors do little to adjust for a manager’s style. Terminated managers are predictably dominated by representatives of recently underperforming (and often newly cheap) styles. Will these terminated managers be replaced with another underperforming manager, representing a newly cheap style? Hardly.3 They are most likely to be replaced with a recently impressive manager, one that is representing a newly expensive style and thus positioned for future underperformance.
This standard procedure of seeking managers with stellar past performance is both intuitive and comfortable. Our ancestors on the African veldt did not survive by running toward a lion, so it should not be surprising that we, today, still instinctively avoid what has caused us pain and losses, while seeking more of what has given us joy and profits. This behavior is innate. Yet, in investing, what seems intuitive and comfortable rarely pays off—all too often, it leads to bad choices. In the capital markets, whatever has recently mauled us in the past is (slightly) more likely to comfort us in the future, than to inflict further pain.
Underperforming strategies are often newly cheap and might well be better candidates for new assets, not for termination. For example, the Russell Value Index underperformed the market in the last three years of the tech bubble by an enormous 2,400 basis points (bps), laying the foundation for 39% more wealth generated by value versus the market in the next three years and 49% more wealth in the subsequent five years.4 One of us (Arnott) had clients declaring in the year 2000—the height of the tech bubble—they will never again invest with a value manager. It is easy to understand those investors’ frustration when the wealth generated by the Russell 1000 Value Index (and most value managers) was fully 24% less than the broad market Russell 1000 Index over the last three years of the tech bubble. The irony is that, if no adjustment is made for style, and for the manager’s current relative valuation, as compared with past norms, the star manager with brilliant results is often a better candidate for termination than a manager who has recently disappointed. The outcome of this performance-chasing practice (both in manager selection and investment style) makes investors losers from poor timing.5
If a manager has performed brilliantly and the manager’s assets are at record-high valuations relative to the market, investors should arguably redeem, not invest more. If a manager has performed badly and the manager’s assets are at an exceptionally cheap relative valuation, investors should seriously consider topping up, rather than firing the manager. We are not suggesting that past performance is irrelevant, only that it’s a terrible predictor of future prospects. Likewise, past success is not always a sell signal.
Just like ignorance of past performance is self-evidently naïve, so is ignorance of current valuation levels. When investors use a richer toolkit that combines past performance and current relative-valuation levels, the decision will not always be to fire the winners and hire the losers, or vice versa. If a fund has outperformed, but the assets are not at newly lofty valuation levels, that manager is amply deserving of consideration for a far larger allocation. Conversely, if a manager has had bad performance relative to the market, and the assets have not become massively cheaper, that’s really bad news. In most cases, this should be grounds for immediate dismissal.
If Skill Exists, Does It Persist?
Performance chasing could be useful if past performance were a good indication of management skill. Sadly, scant evidence exists that skill can be identified from performance alone.6 That said, we shouldn’t ignore past performance altogether. Poor performance can indicate sloppy execution, high transaction costs, or high fees, all of which will erode performance in the future every bit as much as they have in the past. Therefore, it makes just as much sense to fire poor performers who routinely lose money as a consequence of elevated trading costs or fees as it does to fire managers with deeply misguided strategies.
Can we distinguish such managers from the managers who have underperformed by dint of their strategies becoming newly cheap? Yes, we can, albeit without great precision. Relative valuation is the key. Relative valuation and performance go hand in hand. Equity factors, just like individual stocks or different asset classes, can get cheap at certain times and expensive at other times. If mean reversion occurs in valuations, the expensive valuation today is likely to disappoint in the future. Reciprocally, today’s cheaply valued factor or strategy is likely to offer strong future return prospects.
Our analysis relies on data from Morningstar Direct Mutual Fund Database for the period January 1990–December 2016. The dataset reports historical monthly total returns for all mutual funds, including those liquidated or merged. This ensures our mutual fund dataset is largely free of survivorship bias. We limit our sample to include US open-end long-only active equity funds with at least two years of return history, as of December 2016, and which have at least one of the A-share, no-load, and institutional share classes.7 For the funds with multiple share-classes, we select the share class with the earliest start date.
Our final US fund sample consists of 3,331 funds—a mixture of live funds and funds that no longer exist today. Figure 1 illustrates the evolution of the fund sample over time. Our sample size, the blue line, begins with 420 funds in 19908 and gradually increases to a peak of 2,342 funds in 2008, before falling to about 1,800 funds in 2016 (on the left scale). The green sawtooth line tracks the percentage of funds with reported returns, but without reported expense ratios (on the right scale). Information on fund expense ratios is not available for many funds, especially in the early part of the sample.9 Our analyses use net-of-expense fund returns, which is how Morningstar Direct reports these data.
The funds in the database are then classified into one of nine groups: by size into large-, mid-, and small-cap, and by style into value, blend, and growth. When we perform the analysis relative to a peer group, we equally weight the performance of all funds in each of the nine categories to produce the average peer-group performance.
The Danger of Performance Chasing
Many investors routinely fire recently underperforming managers and hire recently outperforming managers. This rule makes intuitive sense, but does it really help the investor? To answer the question we combine all the data into one regression and use past performance as an explanatory variable to forecast subsequent performance. We use net-of-expense performance because it is the performance that investors get to keep. To control for persistence in poor performance arising from fund expenses, we add a second variable—trailing average fund-expense ratios—to the regression. Managers who suffer a recurring performance drag from high expense ratios are likely to underperform in the future.10
Multiple ways are available to measure performance. We study four variations: 1) simple return, 2) return relative to the market, 3) return relative to the peer group, and 4) return controlling for the Fama–French five factors (market, value, size, profitability, and investment factors) plus momentum and low-beta factors.11
We examine fund performance using three horizons:
- one-year past performance, to forecast subsequent one-year performance;
- three-year past performance, to forecast subsequent three-year performance; and
- five-year past performance, to forecast subsequent five-year performance.
In the regression, we pool observations across different time periods.12 Table 1 reports the results of our bivariate regression analysis. Panel A displays the results of past performance forecasting subsequent performance, and Panel B presents the results when we consider the trailing expense ratio. In the latter case, the relationship between expenses and subsequent performance is reliably negative. We are far from the first authors to document this finding; for example, Barber, Odean, and Zheng (2005) show that, with solid statistical significance, higher expenses are associated with worse performance. Nevertheless, our findings are a powerful reminder that high fees often imply lower returns.
The on-diagonal results reported in Panel A of Table 1 focus on the key question of our study: What is the relationship between past and future fund performance?
Simple return. This variable pools together information across time and across funds, and produces the strongest relationship in this set of results: past high return usually leads to losses, whereas past low return usually leads to gains. These relationships are reflected in a negative slope: past winners are future losers. Because we are pooling across time, mean reversion in market performance is likely responsible for a significant portion of this result. And, of course, we cannot use this information to cross-sectionally differentiate the managers at any one time.
Panel A of Figure 2 shows the three-year subsequent performance of the quintiles of funds sorted on past performance (and controlling for past fees): recent winners, on average, underperform recent losers by 1.1% a year (10.5% for the loser quintile minus 9.4% for the winner quintile). As in the regression results, the bar chart results pool observations across different time periods. Despite not being able to use this observation to cross-sectionally differentiate the managers, it still has profound implications.
Joe Kennedy famously said on the eve of the 1929 stock market crash: “When shoeshine boys have tips, the stock market is too popular for its own good.” The negative relationship between a manager’s past and future simple returns means that when your cab driver or bartender (shoe shine boys are less common these days) tells you about an investment with recent double- or triple-digit returns—beware! That may just be the signal to stay away from the market, and most particularly, from the winningest funds. Reciprocally (from repeated personal experience in 1974, 1982, 1987, 2002, and 2009), when you hear reasonably savvy people saying they’ll never invest in stocks again, chances are stocks are at extremely low valuations and are a bargain.13
Return relative to the market. We also observe a negative relationship when we examine the variable return relative to the market, albeit a less powerful relation than in the case of simple return: past outperformance relative to the market leads, on average, to future underperformance, while past underperformance is usually followed by future outperformance. Unlike in the case of simple return predictability, the return relative to the market does not depend on the variation in market performance. Also, the relationship is statistically weaker compared to the simple return, indicating that mean reversion in the market is responsible for much of the simple return predictability. Panel B of Figure 2 shows the three-year performance of quintiles of funds sorted based on past performance relative to the market, and controlling for past fees. We see the recent winners, on average, underperform the recent losers by 1.0% a year (0.7% for the loser quintile minus ?0.3% for the winner quintile).
Whereas the simple return predictability helps us make two decisions—how much to allocate to equity (if at all) and which managers to invest in—the relative-performance results help us only with the latter decision. The mean reversion in the relative-performance results implies that the proverbial “three years down and out—controlling for fees” manager selection rule is a money-losing strategy, even if only modestly so. Investors able to stay the course with managers, despite their underperformance, and to routinely consider discarding managers after brilliant recent performance, will end up with greater eventual wealth, even if the ride may be bumpy at times.
Return relative to peer group. To compute this variable we subtract the average performance of all the funds in the group the fund belongs to (as identified by size and style) from the fund’s performance. Unlike in the case of the simple return or the return relative to the market, we do not find mean reversion in performance once we control for manager peer-group performance. The observation that performance becomes weaker when we move from simple to relative performance, and disappears completely when we control for size and style, points to the likely sources of outperformance: 1) the mean reversion in market-wide performance we observe in the simple return results, and 2) the mean reversion in style we observe in both the simple return and the return relative to the market.
A significant body of research exists on overall market predictability. Later in this article we will explore the second driver of fund relative performance, style-return predictability.
Return controlling for factor exposure. The most restrictive of the four variables is the return that we control for factor exposure. This variable allows us to examine persistence in performance after controlling for a very comprehensive list of factor exposures. Here, we (finally!) find a healthy degree of persistence.
We would like to emphasize three important caveats:
- Although seven-factor-adjusted past return is a pretty good predictor of seven-factor-adjusted future return, an investor cannot spend seven-factor-adjusted future return!
- The set of factors we control for was not known during the majority of our sample period and thus introduces look-ahead bias into our analysis.
- When we examine the off-diagonal predictability based on the past alpha, the persistence either becomes insignificant or switches signs, depending on the horizon.
Our findings suggest caution: The results may be less robust than they seem. Seven-factor-adjusted past return is not a good predictor of simple return, relative return, or even performance relative to peers.
Overall, we observe mean reversion in performance especially on the three- and five-year horizons. The sobering implication is that the usual practice of firing recent losers and hiring recent winners achieves the exact opposite of what is intended. When we seek to allocate capital to the most skilled managers, the usual practice of manager rotation instead allocates capital to funds and managers that are more likely to disappoint!
Panel B of Table 1 conveys a commonsense finding that higher fees mean lower returns. Interestingly, the coefficient is generally between one and two, which means that a 10 bp increase in fees usually costs more than 10 bps in performance (10 to 20 bps, to be specific). It would seem that the more expensive managers also incur more hidden costs. Performance differences are vast, so fixating on a few basis points of difference in fees is foolish, especially when hidden costs will often dwarf the fees. Although the best managers and products often cost more, there is no assurance that paying more will necessarily get you a better manager or product.
Investors clearly understand that higher fees can have a negative impact on their net return, as is evident in the price war in mutual fund fees, but a few basis-points difference in visible fees is far less meaningful in performance impact than the often-large hidden costs.14 For example, switching from a low-turnover strategy to a sloppily constructed strategy that spends scores of basis points in incremental trading costs can cost the investor dearly in performance.15 The same holds true for the buyers of opaque high-fee products (hedge funds and illiquid private investments), for which substantial costs may be hidden from sight.
Why Comfortable Is Rarely Profitable
Last year we published a series of articles studying the link between factor valuations and factor subsequent performance (Arnott et al.  and Arnott, Beck, and Kalesnik [2016 a, b]). The key point of the articles is that, just like individual asset classes or individual stocks, factors tend to perform better from a starting point of trading cheaply, and tend to perform worse after they become expensive. Figure 3, Panel A, reproduces the charts for two factors we studied in our earlier work—value and size—showing the link between each factor’s relative valuation and its subsequent return.
Each factor is based on a long–short portfolio. Value is long a value portfolio, and short a growth portfolio; size is long a small-cap portfolio, and short a large-cap portfolio. The relative valuation is based on the valuation of the long portfolio relative to the short portfolio. This relative valuation is a blend of four relative-valuation ratios: price to book, price to five-year average sales, price to five-year average cash flows, and price to five-year average dividends, each computed for the long portfolio relative to the short portfolio.16 The average valuation indicates whether the factor is trading cheap or rich relative to historical norms.
For each point on Panel A, the position on the horizontal axis represents the starting relative valuation for the factor from some start date, while the vertical position shows the factor return over the following five years. The negative relationship between the valuation and subsequent return illustrates that as the factor gets cheap it tends to perform better; as it get expensive it tends to perform worse. Although we only display the relationship for the value and size factors, the same relationship holds for most factors and strategies we examined in the US, international, and emerging markets.17
The timing of factors’ becoming cheap or expensive is not random. Figure 3, Panel B, which spans the full historical sample period of 1967–2016 for eight of today’s most popular factors, shows that previous 10-year factor returns and the subsequent factor valuation are powerfully correlated. Lousy past performance leaves factors cheap, while brilliant past performance leaves them expensive. The strong and consistent positive correlations between past performance and the resulting relative valuations suggest that equity factors tend to get cheap as they underperform and tend to get expensive as they outperform. And, as we saw in Panel A, expensive factor relative valuation presages lousy returns and cheap pricing presages brilliant returns.18
Panel B provides a plausible clue for why past winners tend to disappoint, while past losers tend to positively surprise. Most funds have persistent factor exposures, and those exposures explain the lion’s share of the fund’s return in excess of the market. When a factor performs poorly it drags down the fund’s return, which contributes to cheap valuations that lead to future superior performance. It also works the other way around: stellar performance of a factor will boost the fund’s return, pushing its valuations higher until they are very expensive, and setting the fund up for future disappointing performance. Plus ça change, plus c’est la même chose.
Let’s test our conjecture that the mean reversion in fund performance is driven by cycles in factor valuations, which presents a potential opportunity to use factor relative attractiveness to gauge fund relative attractiveness. Beyond establishing a link between valuation and subsequent return, our “Look Before You Leap” and “Alice in Factorland” (Arnott, Clements, and Kalesnik  and Arnott, Kalesnik, and Wu ) series of articles show that investors can quantitatively forecast future factor returns based on a factor’s current relative valuation.
An exponential line of best fit for the data in Figure 3, Panel A, provides the average historical relationship between a factor’s valuation and its subsequent return, indicating that we can forecast the forward-looking factor return based on the current valuation level relative to its historical norm. Any model calibrated with in-sample data will, of course, do a decent job “forecasting” factor performance in the same sample period. Arnott, Beck, and Kalesnik (ABK) (2017) take this a step further, showing that such valuation-based models can also forecast subsequent factor alpha out of sample. We use the method described by ABK to create factor return forecasts for the three most popular factors: value, size and momentum.
The relevant implication for fund performance is that multiplying valuation-based expected factor-return predictions by historical fund factor loadings allows us to compute a factor-based expected fund alpha. Both the expected factor-return prediction and the historical factor loadings for each mutual fund are calculated based solely on information that would have been available at that time, without look-ahead bias. If our conjecture is correct, the implied expected fund return should predict the fund’s future performance.
To test this hypothesis we use relative valuations to estimate the expected return for the three most popular factors: value, size, and momentum.19 To estimate fund factor sensitivity as well as the factor return forecast, we use only the information available before the forecast period in order to exclude look-ahead bias (details of the method are described in the appendix). We use a pooled regression. We display the results of the predictive regression in Table 2, Panel A. Consistent with our conjecture, the factor-implied return is strongly predictive of the fund’s return relative to the market. While the R2 of 0.068 may seem low to statistically inclined readers, it corresponds to a correlation of over 25%. If we are forecasting mutual fund relative performance with an information ratio of 25%, this is roughly 25% as valuable as having a clairvoyant year-ahead list of mutual fund performance relative to the market.20 Most investors would pay handsomely for such a list.
Previously, we observed that both a fund’s performance over a three-year period and the fees it incurred in the past are predictive of its subsequent performance. We also observed that past multivariate model alpha is predictive of subsequent alpha, although it is not predictive of subsequent return or return in excess of the market. We combine these variables with the factor-implied return to run a multivariate regression using all four variables in order to forecast the fund return relative to the market. We display the results in Table 2, Panel B.
Just like before, the multivariate alpha does not help forecast return relative to the market. Interestingly, past three-year return, a respectable predictor in its own right, loses its predictive power in this multivariate setting. Only the expense ratio and the factor-implied returns maintain their statistical significance. The fact that fund-style forecast subsumes the past return implies we have correctly identified an important mechanism for fund-return mean reversion. Perhaps fund-return mean reversion comes primarily from fund factor exposures and factor valuation cycles.
As in past articles, we test the robustness of our findings in the US market by repeating our analysis in an international setting. We display in Table 3, Panel A, the results of a bivariate regression on a set of international funds, using factor-implied returns and past expenses to forecast subsequent fund performance. Despite the fact that the number of funds are lower in the international sample than in the US sample, and that the factor-implied model tends to have weaker explanatory power for fund relative performance as evidenced from the reduced R2 of 0.020 (we provide the relevant statistics in the appendix), we still find a statistically significant relationship between the factor-implied return and subsequent performance in this out-of-sample test. That seemingly low R2 corresponds to a 14% information ratio, or correlation with subsequent performance. Although this is hardly a stupendous correlation, it’s not bad.
As in the US sample, we also run a multivariate regression, which includes the variables of fees, past three-year relative performance, and past multivariate alpha. Table 3, Panel B, reports our results. In the international sample, as in the US market, only fees and the factor-implied model retain statistical significance. The predictability of future return based on past return seems to be subsumed by factor-implied valuations and fees.
How Should Managers Behave?
Managers, like their clients, can fall prey to performance chasing. Some strategies (our own Fundamental Index™ comes to mind) back away from the assets, sectors, or styles that have led to sustained success and taking gains once they are large enough to matter, but most managers don’t think or act this way. Few managers, after a period in which they have performed well, can pull back on what has been working so well for them. In fact, the manager’s decisions and style are likely to be reinforced by the accolades of their clients and the investment punditry.
Reciprocally, when a fund manager has had a rough patch (for example, the ubiquitous two- or three-year horizon that gets them in trouble), the pressures are intense to change course; the fund company may fire the manager, thereby forcing a change in the portfolio. Investment committees typically consist of successful business managers, who did not succeed by doubling down on failure. We would argue, backed by our research findings, it is precisely at this point that the investment committees should be doubling down on the expectation of outperformance, instead of flinching. Again, Fundamental Index does exactly this—ramping up exposure to the sectors, styles, and assets that have hurt us—but most managers don’t behave this way. Even advocates of momentum would readily acknowledge that momentum acts over months, and perhaps quarters, but not years. Over these longer spans, residual reversal takes over. Empirical evidence is clear: the longer a winner has been winning, or a loser losing, the higher the likelihood of residual reversal prevailing and rewarding the contrarian.
If a manager has performed well for several years, and is now invested in assets with newly lofty valuations, investors are usually better off staying away—unless the manager takes the initiative to proactively remove the sky-high assets from the portfolio. Of course, this does not apply to those very rare managers able to consistently generate alpha by picking the next Google-like star growth stocks. But, it’s harder still to identify those managers and funds in advance! Reciprocally, if the manager’s performance in recent years has been disappointing, and the manager now holds assets with record-low valuations, this manager is a buy—unless the manager has responded to client or investment committee pressure and has abandoned the newly cheap assets, or the manager has been fired and replaced, with a new manager, less likely to stay the course with the newly cheap assets.
The crucial point here is that investors need to look forward and develop a measure of expected fund returns. This forecast depends on the factor exposures, factor expected returns (influenced by value), fees, and manager’s ability to select securities within each style group. We recognize that valuations will often point in the opposite direction from the intuitive and comfortable practice of making manager-selection decisions based on firing recent losers and hiring recent winners. If this means less portfolio turnover, that’s probably a good thing, because it may materially reduce trading costs. Given that what is comfortable is rarely profitable, having the discipline to follow a much-less orthodox and quite uncomfortable approach to investment may translate into far better performance.
Additionally, with an understanding of the predictive efficacy of relative valuations in factor tilts and strategies, investors now have an objective reason to avoid the blunders of performance chasing. We hope that some in the investment consulting business will begin to show both performance and relative valuation to provide their clients a richer toolkit for making manager hiring and firing decisions.
Conclusions: Learning to Live with Discomfort
Institutional and retail investors alike, and their advisors and consultants, often make the mistake of assuming past fund performance is an indication of skill, which leads to the common practice of terminating the poorly performing funds and replacing the fired manager with a fund that has had stellar past performance. This practice has three flaws: 1) past is not prologue, past winners are often future losers, and vice versa; 2) persistent manager skill is rare (outside of negative skill, in the form of high fees, high trading costs, and sloppy implementation, which are all less rare than they should be); and 3) other than recurring costs, most performance is mean reverting.
We do not advocate abandoning the reliance on past performance. We advocate a richer toolkit— pairing past performance with current valuation—for a better-informed decision. Of course, fees and a manager’s ability to select stocks are also extremely important. Even the most exceptional managers and funds will have extended periods of disappointment from time to time. These exceptional managers and funds will be fired at the worst possible time, often to be replaced with mediocrities enjoying a temporary bit of good fortune. Pairing valuation-based information with past performance can help us to avoid both errors.
Our research, demonstrating that factor valuation can be used to predict fund and strategy performance, urgently suggests a change in how we allocate money among managers. Because it’s impossible to know where the top is, and we don’t want to sell too soon, “selling high” is not easy. When we sell high, and the asset moves higher, we feel foolish. “Buying low” is even harder. Anything that’s newly cheap has inflicted pain and losses in its path to low prices. It’s impossible to know where the bottom is, so buying low inevitably leaves us looking and feeling foolish until the turn. “Buy low, sell high” is therefore a painful path to success. Nevertheless, we hope our findings encourage investors to consider joining us in moving out of our respective comfort zones. The capital markets do not reward comfort. In investing, we generally find our best rewards in our discomfort zone.
