Evaluating an emerging market for portfolio diversification comes down to four criteria: macroeconomic stability, the political and regulatory environment, the ESG profile, and market liquidity and structure. Robeco, whose asset managers select among a broad array of countries, describes their own process as a focus on macroeconomic fundamentals—GDP growth rates, inflation, currency stability, and fiscal policy strength—complemented by ESG considerations including the political and regulatory environment, corruption levels, and regulatory transparency. The trade-off is consistent across every criterion: the growth and diversification emerging markets offer are paid for in volatility, weaker institutions, and less-developed financial systems.
Why Emerging Markets Offer Unique Diversification
The case for emerging markets begins with return patterns that do not move in lockstep with developed markets. Franklin Templeton notes that over time, emerging market equities have exhibited meaningfully different return patterns from North American markets, reflecting distinct economic and earnings drivers. There is also a geographic dimension: emerging markets account for a growing share of global economic activity, consumption, and capital investment, yet their weight within global equity portfolios remains modest relative to that contribution.
That mismatch matters practically. Exposure obtained indirectly through global funds can understate this reality, particularly during periods when developed-market leadership narrows. Aberdeen Investments frames the same opportunity in terms of higher growth potential, expanding consumer markets, and diversification benefits that may help investors capture long-term opportunities beyond developed economies. The strategic role, in other words, is not simply chasing growth but accessing economic drivers a North American-heavy portfolio does not contain.
Criterion 1: Macroeconomic Stability and Growth Potential
The first screen is the health and resilience of the underlying economy. Robeco's country selection starts from GDP growth rates, inflation, currency stability, and fiscal policy strength—indicators that reveal whether growth is durable or built on fragile foundations. S&P Global adds a structural caution: many emerging economies are often concentrated in very few sectors or commodities, which amplifies the macroeconomic risk when a single export category turns.
The associated risk is sharper market movement. Aberdeen attributes emerging market volatility partly to weaker economic structures and currency fluctuations, which can produce sharper swings and higher investment risk than developed markets. The trade-off here is direct: a fast-growing economy with concentrated exports and an unstable currency offers more upside and more downside than a slower, more diversified one.
