How Factor Investing Behaves Across Global Markets

At their core, the rules of factor investing are universal. For example, value captures the tendency of lower-priced securities to behave differently over time, while momentum reflects the persistence of recent performance, and quality emphasizes balance-sheet strength and earnings stability. These concepts translate across markets, but the results they produce can vary significantly from one region to another.

In developed markets, such as the United States and Western Europe, factor performance tends to occur within highly competitive environments typically characterized by deep liquidity and extensive professional research. Data from international studies? indicate that in these more efficient corridors, value and momentum premia have historically been smaller, particularly among large-capitalization stocks. Consequently, capturing these returns can require more precise execution than in less efficient settings.

Emerging markets often tell a different story. According to the paper Do the Size, Value, and Momentum Factors Drive Stock Returns in Emerging Markets?, emerging markets are often shaped by frictions that differ from the more efficient environments of the U.S. and Europe. The authors note that these markets often experience slower information diffusion, higher transaction costs, and lower institutional participation. A less developed financial infrastructure may also lead retail investors to hold less optimal portfolios, which may create mispricing opportunities that the value factor can exploit. The study also finds that value and momentum returns in emerging markets are relatively insensitive to global funding liquidity, market liquidity risk, and credit risk, suggesting these markets are not yet fully integrated into the world economy.

One potential benefit of global factor investing is that factor performance can vary across regions. When a factor is underperforming in one market, it may be doing better elsewhere, reflecting differences in economic cycles, investor positioning, and market structure. Over time, this dispersion has offered a way to broaden diversification beyond traditional asset class allocations.

A global approach might, for example, pair value exposure in Europe with momentum exposure in North America or Asia. The intent is to help smooth regional or cyclical fluctuations.

Factors don’t move independently of the global economy. In strong growth environments, pro-cyclical factors such as momentum and size often lead. In slower or more uncertain periods, investors tend to favor defensive traits like low volatility and quality.

As markets have become more interconnected, these rotations can happen faster. That makes diversification across both factors and regions an important consideration rather than relying on a single theme or market regime.

A global multi-factor approach aims to balance potential sources of return while managing regional and cyclical risks. That typically means combining complementary factors like value and momentum, diversifying geographically to avoid dependence on any one market and monitoring correlations and factor cycles as conditions evolve.
