Swedroe: Active's Emerging Market Flaws

May 02, 2018

As the director of research for Buckingham Strategic Wealth and The BAM Alliance, I am often asked to comment on articles or papers that make a case for active management being the winning strategy. Recently, I was asked to comment on a February 2018 article from Advisory Research titled “Emerging Markets: Active vs Passive.” At the end of 2017, the firm managed more than $7 billion in assets.

Not surprisingly, given the article’s position, Advisory Research presents evidence from an eVestment database of more than 300 institutional actively managed emerging market (EM) funds that shows a majority of active managers outperformed their EM benchmarks, and did so by a wide margin (on average 1.57%). The article thus concluded active management is the winning strategy in EM.

Before you jump to that same conclusion, let’s examine some other evidence. I’ll begin with a look at the latest S&P Dow Jones Indices SPIVA scorecard, from year-end 2017.

SPIVA Verdict

SPIVA data shows that, for the last 5-, 10- and 15-year periods, 78%, 85% and 95%, respectively, of actively managed, publicly available EM mutual funds underperformed their benchmarks. That’s a stark contrast to the figures presented by Advisory Research.

In addition, over the 15-year horizon ending 2017, on an equal-weighted (asset-weighted) basis, active EM funds underperformed by 2.6 percentage points (1.5 percentage points).

Note that it is possible that some of the difference in the results could come from the choice of benchmark index. S&P Dow Jones Indices uses its own index in the SPIVA scorecard, not the MSCI index used by Advisory Research. While I don’t believe it’s an issue in this case, often, proponents of active management will choose the easiest-to-beat benchmark (such as the Russell 2000 instead of the S&P SmallCap 600 Index or the CRSP 6-10 Index for small stocks) to make their argument.

An explanation for the difference in the results from the two databases might be that active institutional funds have lower expense ratios than publicly available active mutual funds. However, given the magnitude of the underperformance recorded in the SPIVA data, that most likely cannot be the answer. It seems to me a more plausible explanation is that we don’t really have an apples-to-apples comparison in the eVestment data, at least as presented.

Advisory Research compared active EM funds to the MSCI Emerging Markets Index, which is similar to the S&P 500 Index in that it consists of large-cap companies in its respective market. It’s possible the outperformance shown by institutional EM funds was due to their managers loading more heavily on small and value stocks than the large-cap index used in the analysis.

Factors Work In Emerging Markets

In their 2016 study, “Emerging Market Portfolio Strategies, Investment Performance, Transaction Cost and Liquidity Risk,” Roberto Violi and Enrico Camerini found that factor-based investment strategies historically have worked in EM as well as in developed markets. We can see that by examining the returns of three passively managed funds from Dimensional Fund Advisors (DFA). (Full disclosure: My firm, Buckingham Strategic Wealth, recommends DFA funds in constructing client portfolios.)

The longest period for which data is available for all three funds begins May 1998. From May 1998 through February 2018, the MSCI Emerging Markets Index (again, a large-cap index) returned 8.1% and, according to data from DFA, the comparable DFA Emerging Markets Portfolio (DFEMX) returned 8.8%. The DFA Emerging Markets Value Portfolio (DFEVX) returned 11.2% and the DFA Emerging Markets Small Cap Portfolio (DEMSX) returned 11.8%. Both DFA’s small-cap and value funds outperformed the benchmark MSCI index by more than 3 percentage points. That’s more than twice the margin of average outperformance reported in the eVestment data shown by Advisory Research.

Thus, it is certainly possible the results reported were not risk-adjusted for factor exposures. In other words, the alpha reported from the analysis of the eVestment data might just have been nothing more than beta, or loading on common factors. If this were, in fact, the case, and the active institutional EM funds’ returns had been properly compared with more similar indexes, perhaps the alpha would have disappeared entirely—or turned negative.
