We study the impact of exchange rate fluctuations and political risk on the risk premiums reflected in cross-sections of individual equity returns from Mexico, a country that has ex? perienced significant monetary and political turbulence. Indicators from Mexico's currency and sovereign debt markets are employed as proxies for exchange rate and political risks. We find some evidence of equity market premiums for exposure to these risks. The results suggest common factors in emerging market equity, currency, and sovereign debt markets, and have several implications for corporate and portfolio management and for the use of emerging market data by researchers.
