Should I Stay Or Should I Go: 4 Arguments For Investing In Emerging Markets

by: Parametric Portfolio Associates, LLC


Given the recent negative returns in the emerging markets, many clients and consultants are asking us to provide arguments for why an investor should stay in the asset class "now".

We make four arguments, which we believe provide ample justification for why an investor should want to stay invested in the emerging markets.

And, if not currently invested, why an investor may consider "now" to be an opportunity to add exposure.

Looking at Cyclically Adjusted P/E ("CAPE") ratios, it is clear that emerging market stocks are much cheaper than developed market stocks, as demonstrated by the much higher CAPE ratios observed in developed markets.1 In addition, when compared to their historical averages, we also see that U.S. equities are at extended valuations while both developed and emerging markets are currently standing below their average measurement.

Given the data in Figure 1, most valuation-sensitive investors would find the emerging markets attractive on both an asset-class relative basis, as well as on an historical basis. The fact that many investors are considering selling emerging market assets to purchase U.S. equities is at odds with this data.

Dollar Strength

A large part of the recent decline in emerging market returns is due to the sharp rally in the U.S. dollar. That is, equity markets in a foreign country's base currency may have increased, but when translated into dollar terms, the depreciation of the foreign currency versus the dollar results in a loss when the returns are stated in dollar terms. One way of measuring the impact of currency movements on the index is to examine local returns, which correspond to those experienced by investors who have hedged all currency movements in their portfolio. As Figure 2 shows, one can see how recent returns in the emerging market asset class have been negatively impacted by this rally in the U.S. dollar.

Given this, we would emphasize that recent experience is not a good representative of forward expectations of currency impacts on emerging market returns.


Emerging and frontier countries are not as integrated into the global economy as developed countries, due to the former possessing more internally-focused economies and industries. Aside from some of the largest developing nations, the stock markets of these countries are driven more by their individual dynamics than events in the global markets. This naturally leads to equity markets which exhibit low correlation to the equity markets of the developed world. This is confirmed by Figure 3, which shows a persistently lower correlation between U.S. equities and emerging market stocks than that which exists between U.S. equities and international developed stocks.

Recent experience in the emerging markets may raise the question of why any allocation exists, given that emerging markets have dropped, while developed markets have risen. However, we would view this as evidence that the asset class remains an effective diversifier, as the very nature of diversification is for an asset class to be down when other asset classes are up despite our human tendency to want assets which both diversify and only go up.

Unconscious (& Unconscionable) Underweight

If one uses market capitalization as a frame of reference, then the exclusion of the emerging markets represents a tremendous underweight from a neutral position. To be exact, the MSCI ACWI Index's allocation to EM is currently 9.6%, so by not holding emerging market equities, an investor is essentially saying he hates the asset class so much, he would like to hold a nearly 10% underweight to a neutral position. In conversations with clients, we rarely find a level of conviction which matches the magnitude of this bet.

While these latter examples would typically be seen as bordering on foolhardy by most investors, we would argue the exclusion of emerging market equities from one's equity portfolio is equally aggressive.


Recent performance in the emerging markets asset class has caused such a degree of fear, that for many investors the strategic reasons for owning the asset class no longer seem quite so compelling. In this brief we have laid out supporting arguments that should assist in further motivating an investment in emerging markets equities. Based on generally used valuation metrics, the asset class is cheap versus its historical average, and versus other asset classes; its recent returns have been savaged by currency impacts which are unlikely to be repeated; it remains a powerful diversifier to an investor's portfolio; and an elimination of the asset class would represent a bet which is larger than the conviction of many making the bet. Perhaps the most germane advice is to repeat Warren Buffett's homily that investors should, "Be fearful when others are greedy. Be greedy when others are fearful." The above arguments have hopefully shown that there are a number of logical arguments for investors to be greedy, instead of fearful, when it comes to emerging market equities.
