We have just published the midyear 2019 instalment of the Morningstar Active/Passive Barometer. The Active/Passive Barometer measures active fund managers’ performance relative to their passive peers across 20 Morningstar Categories that together account for $12.5 trillion in investor assets, or about 64% of the U.S. fund market. Here, I’ll discuss how investors might use this report to better understand the odds of picking successful active managers and how they might winnow the field to improve their chances of partnering with those most likely to do well in the future. Lower fees.
Base rates
In his book Thinking, Fast and Slow, Nobel Prize-winning psychologist Daniel Kahneman discusses how he stumbled upon two different approaches to forecasting while working for Israel’s Ministry of Education to write a high school textbook about judgment and decision-making. Kahneman and his longtime collaborator Amos Tversky ultimately branded these two schools of forecasting “the inside view” and “the outside view”. The inside view is deeply personal. In constructing a forecast based on the inside view, we focus very narrowly on our own unique experiences and situation and extrapolate from there. (For example, I’m an above-average driver with a squeaky-clean driving history about to go on a short trip in fair weather. The odds of me getting in a fender bender are almost nil.) On the other hand, a forecast based on the outside view starts with a survey of the broader population and is refined based on any specifics regarding the circumstances. (Start with the odds of any driver getting in a fender bender regardless of driving history, the distance traveled, or weather conditions, and go from there.) The outside view is anchored to a base rate. Kahneman explains the concept of base rates in Thinking, Fast and Slow:
” … It provided a reasonable basis for a baseline prediction: the prediction you make about a case if you know nothing except the category to which it belongs. This should be the anchor for further adjustments. If you are asked to guess the height of a woman and all you know is that she lives in New York City, for example, your baseline prediction is your best guess of the average height of women in the city. If you are now given case-specific information–that the woman’s son is the starting centre of his high school basketball team–you will adjust your estimate.”
Depending on the problem at hand, starting from the outside and working in may be a recipe for better predictions and, thus, better decisions. I would argue that this approach has a multitude of applications within the realm of investing. I’ll share with you some base-rate data that is specific to success rates among active fund managers, and how investors can work from the outside to begin to zero in on winners.
Morningstar Active/ Passive Barometer
The Morningstar Active/Passive Barometer is a semiannual report that measures the performance of U.S. active managers against their passive peers within their respective categories. The Active/Passive Barometer report is unique in the way it measures active managers’ success relative to the actual, net-of-fee performance of passive funds rather than an index, which isn’t investable.
The central question the report seeks to answer is: If an investor were to select an actively managed fund at random from a category, what are the odds that fund will survive and outperform its passive peers in any given time period?
We measure active managers’ success relative to investable passive alternatives in the same category. For example, an active manager in the U.S. large-blend category is measured against a composite of the performance of its index mutual fund and exchange-traded fund peers (Vanguard Total Stock Market Index (VTSMX), SPDR S&P 500 ETF (SPY), and so on). Specifically, we calculate the equal- and asset-weighted performance of the cohort of index-tracking (“passive”) options in each category that we examine, and we use that figure as the hurdle that defines success or failure for the active funds in the same category. The magnitude of outperformance or underperformance does not influence the success rate. However, these data are reflected in the average return figures for the funds in each group, and the distribution of 10-year excess returns for surviving active funds, which we report separately.
We believe this is a better benchmark because it reflects the performance of actual investable options and not an index. Indexes are not directly investable. Their performance does not account for the real costs associated with replicating their performance and packaging and distributing them in an investable format. In addition, the success rate for active managers can vary depending on one’s choice of benchmark. For example, the rate of success among U.S. large-blend managers may vary depending on whether one uses the S&P 500 or the Russell 1000 Index as their basis for comparison. By using a composite of investable alternatives within funds’ relevant categories as our benchmark, we account for the frictions involved in index investing (such as fees) and we mitigate the effects that might stem from cherry-picking a single index as a benchmark. The net result is a fairer comparison of how investors in actively managed funds have fared relative to those who opted for a passive approach.
We measure each fund’s performance based on the asset-weighted average performance of all its share classes in calculating success rates. This approach reflects the experience of the average dollar invested in each fund. We then rank these composite fund returns from highest to lowest and count the number of funds whose returns exceed the equal-weighted average of the passive funds in the category. The success rates are defined as the ratio of the number of active funds that both survived and outperformed the average of their passive peers to the number of funds that existed at the beginning of the period. Given this unique approach, our field of study is narrower than others’, as the universe of categories that contained a sufficient set of investable index-tracking funds was fairly narrow at the end of June 2009, the starting point for our latest study. The number of categories we include in this study has expanded over time and will continue to grow.
We also cut categories along the lines of cost. Cost matters. Fees are the one of the best predictors of future fund performance. We have sliced our universe into fee quintiles to highlight this relationship.
As is apparent in the accompanying table, actively managed funds have generally underperformed their passive counterparts, especially over longer time horizons. In addition, we found that failure tended to be positively correlated with fees (that is, higher-cost funds were more likely to underperform or be shuttered or merged away, and lower-cost funds were likelier to survive and enjoyed greater odds of success). Again, fees matter. They are one of the only reliable predictors of success.
I think the Active/Passive Barometer is a useful starting point for investors looking to take the outside view when it comes to picking successful active managers. As for working from the outside in, it is little surprise that focusing on fees is the best way to boost your base rate.
