Emerging Market Allocations: How Much to Own?
Februar 08, 2021
Until recent months, emerging economies had fallen off the radar, after the worst decade for emerging stock market returns since records began in the 1930s. Now, as we expected, investors are coming back, drawn by attractive valuations for both emerging market (EM) stocks and currencies, and record high valuations elsewhere. Once again, we are flooded with inquiries about EM: will this comeback endure? If so, which EMs will do best and—above all—how much to invest?
The answer, in brief, is there are many reasons to expect this EM comeback to endure for the next five to ten years. The top four reasons: a few EMs are prospering as old fashioned manufacturing success stories; the unfolding revival of commodity prices is a bright sign for the many EMs that rely on commodity exports; lacking the resources to spend their way through the pandemic, many emerging world governments have been forced to press painful economic reform, which is likely to accelerate growth in coming years; and finally, the pandemic is also accelerating the digital revolution, and one of the least understood aspects of this revolution is that it is unfolding even faster in emerging markets than in developed ones.
As for where to invest, the simple answer is in markets best positioned to prosper from one or more of the four trends outlined above. The EMs rising as export manufacturers are concentrated in Southeast Asia and Eastern Europe, led by Vietnam and Poland. Those already getting a boost from the commodity price revival include diversified exporters like Brazil, oil and metals exporters like Russia, and exporters of metals critical to green electrification programs, like Chile. The pandemic-inspired reform efforts are widespread but perhaps most dramatic in Indonesia and India. Most intriguingly, the digital revolution is seeing new regional variants of the Chinese and American tech giants rise across every region in EM, from Latin America to Africa and East Asia.
This moment was entirely predictable. Over the last decade, investors had eyes for only two countries, the United States and China, and one sector, tech. But the hot themes of one decade rarely stay hot the next, which is why we have been expecting this revival of the rest—countries outside the superpowers, companies outside big tech—for some time. Following a historically weak decade for EM returns (see Display 1), the gap between EM and U.S. valuations has never been wider. And with the growth prospects of emerging economies rising relative to the United States, these extremes are likely to shift back toward balance.

The mood around EM has changed so fast, the question we get most often now cuts right to the chase: how much to invest in EM?
In this paper, we survey three key approaches used to answer this question, and we find that they suggest an ideal global equity portfolio would include an EM allocation of at least 13% but perhaps materially more. Then we compare this ideal to various sources on how much global investors currently hold in EM equities, and find that today, the actual allocation ranges from just 6% to 8%. Many investors are leaving money on the EM table, at a moment when returns have begun to pick up and—we believe—economic fundamentals suggest the revival has legs.
Three Rational Allocation Strategies
Ever since countries began opening to global capital flows in the 1970s and 80s, research shows, most people have remained not only wary of investing abroad, but wary to an extent not explained by the risks. Levy and Sarnat (1970) were among the first to identify the “home bias” that leads most investors to hold high shares of domestic equities. Since then, a vast literature has examined this bias, but it still defies rational explanation.
To help investors counteract home bias, we have surveyed a number of approaches to help answer the question: how much to invest abroad? There are many models, and we focus on three that we think give the best benchmark and understanding of how to think about EM allocations; each has its limitations, but also provides useful ballpark estimates of how much to sensibly allocate to EM.
GDP WEIGHTING: One approach recommends investors allocate money to foreign equity markets in proportion to each country’s share in global GDP, since this should roughly capture a country’s “relative economic importance” (FTSE Russell, 2014). Today, the 27 countries in the MSCI Emerging Markets Index account for 39% of global GDP (see Display 2).

Even if we correct for a lower free-float share in EM equities and higher dilution, an adjusted GDP weighting approach still suggests that global equity investors should allocate 26% of their portfolio to emerging markets. If we adjust further for the fact that many investors have indirect EM exposure through developed market (DM) companies that earn revenue in EM countries, as well as indirect DM exposure through EM companies with revenue from DM countries, the ideal EM allocation is still sizable, about 17% (see Display 3).1 And as the EM share in global GDP rises, we expect the ideal EM allocation under a GDP weight approach to increase.

MARKET SHARE: A second basic approach is based on share of global market capitalization (Tesar and Werner, 1992). Currently, emerging markets have a 26% share of global market cap, up from 19% in 2009. Note that this share is still lower than the EM share of global GDP (39%). Over time we expect the EM global market cap share to rise and potentially converge with its GDP share, as rising incomes give more and more people the means and need to invest in stocks through retirement funds, insurance policies, and other increasingly sophisticated financial products.
A common variation on this approach uses the EM weight in the MSCI All Country World Index (ACWI). MSCI uses screens to adjust weights for company and country sizes, free-float of equity shares, and liquidity. These screens, which tend to correct for the relatively undeveloped financial systems in emerging markets, put the EM share of MSCI ACWI at 13% (see Display 4). This share has risen from just 1% in 1988 to 13% today, as shown in Display 5,2 and for the same reasons mentioned above, we believe it will rise further in the coming years.

MEAN VARIANCE: The third basic allocation strategy is based on mean variance. Otherwise known as Modern Portfolio Theory (Markowitz, 1952) (Black & Litterman, 1991), or Max Return/Risk, this approach calculates the weight of assets that maximizes expected returns for each asset in a portfolio, given the investor’s tolerance for variance or risk.
Using monthly data since 1988, the year MSCI introduced the EM index, and starting from a portfolio which is 100% allocated to DM equities (MSCI World Index), we examined the monthly returns and volatility of the MSCI World and MSCI EM Indexes and found that the optimal equity portfolio would have allocated 27% to EM and 73% to DM, as shown in Display 6.

One basic objection to that conclusion is that expected EM returns are exaggerated if one uses data going back to 1988 because this period was widely seen as very favorable to EM equities. We would disagree: this period included crises in emerging markets from Mexico to Russia to Southeast Asia, plus the aftermath of the global financial crisis, all of which severely impacted EM equity returns. Nonetheless, to further test our finding, we utilized a series from Global Financial Data for EM equities that goes back to 1925.3 Surprisingly, it showed that over the longer historical period, the optimal allocation to EM equities was even higher, at 37% (see Display 7).
In short, a review of the three standard approaches to EM allocation suggest global equity investors should allocate somewhere in the range of 13% to 39% to EM.

So How Much Do Investors Actually Hold in EM?
There are many sources of data on how much global investors have allocated to emerging market equities, but no matter which one we use, it shows that current allocations represent a low share of overall portfolios, between 6 and 8%.
The EPFR flows database, which covers 346 global equity funds, suggests that the median fund has only 6.4% allocated to emerging markets (Display 8). Morningstar, which reports actual allocation data, yields a similar picture, with the median fund reporting an allocation of 7% to EM equities. And the numbers from eVestment, which aggregates reported holdings for 1,406 global equity funds, suggests the median global fund allocation to EM equities is 8.3%.
Clearly, this 6 to 8% range is significantly lower than any practical theory might suggest, including the 39% suggested by GDP weighting, the 13 to 17% implied by market weighting, or the 27 to 37% suggested by modern portfolio theory.

Summary: The Irony of Underweighting EM Right Now
It would appear then, that most global equity portfolios, no matter how sophisticated, are still guilty of home bias. For decades, they have been missing an opportunity to earn higher risk-adjusted returns by allocating too low a share of their portfolios to international equity. We think their EM allocations are still too low. The analysis above suggests that the typical EM allocation is at most about half, and perhaps as little as one sixth, of what a rational approach would recommend.
The broad paradox of savvy global investors shunning markets that are far from home is very likely to grow over time. As emerging markets continue to gain share in global GDP and global market cap, and to advance in financial depth and sophistication, they will continue to be increasingly attractive, based on the most important allocation models. This gap, between opportunity and allocation, seems to us especially acute today, when an emerging market comeback has already begun, and the economic fundamentals suggest many reasons to believe that it could last. To those wondering where EM growth will come from, the possibilities begin with manufacturing, commodity prices, economic reforms, and the rise of major new internet service industries and companies outside China.
In general, we think the logical answer to “how much” to invest in emerging markets is more. For a host of fundamental and structural reasons, that answer has rarely been more true than it is right now.
There is no assurance that a portfolio will achieve its investment objective. Portfolios are subject to market risk, which is the possibility that the market values of securities owned by the portfolio will decline. Accordingly, you can lose money investing in this portfolio. Please be aware that this portfolio may be subject to certain additional risks. In general, equities securities’ values also fluctuate in response to activities specific to a company. Investments in foreign markets entail special risks such as currency, political, economic, and market risks. The risks of investing in emerging market countries are greater than the risks generally associated with investments in foreign developed countries. Stocks of small- and medium-capitalization companies entail special risks, such as limited product lines, markets, and financial resources, and greater market volatility than securities of larger, more-established companies. Derivative instruments can be illiquid, may disproportionately increase losses and may have a potentially large negative impact on the portfolio’s performance. Illiquid securities may be more difficult to sell and value than public traded securities (liquidity risk). Non-diversified portfolios often invest in a more limited number of issuers. As such, changes in the financial condition or market value of a single issuer may cause greater volatility.
