Resumen de Country factors in stock returns: reconsidering the basic method
Many studies show that country effects dominate in determining the stock return cross-sectional variations. After removing three potential distortions (domestic inflation rate, exchange rate and local risk-free interest rate), we find that the common practice of decomposing the nominal return converted into a single currency misestimates the importance of country effects, and hence may lead to incorrect inferences regarding portfolio diversification.
