Does foreign policy uncertainty predict U.S. stock returns through expected cash flows?
Core argument: Foreign economic policy uncertainty, measured from news article counts across 21 countries, has significant incremental predictive power for excess U.S. stock returns in aggregate and for portfolios sorted on firm characteristics at 6- to 12-month-ahead horizons.
The policy uncertainty index combines news article counts in 21 countries that reflect uncertainty about a broad range of policies, including those by fiscal and monetary authorities, but also the potential economic effects of policies that are not traditionally viewed as economic, such as military actions. We document that foreign economic policy uncertainty [EPU] has significant incremental predictive power for excess U.S. stock returns both in aggregate and for returns of portfolios constructed on firm characteristics, for 6 to 12-months-ahead horizons. We find that [unlike US domestic EPU shocks] foreign EPU shocks operate through a cash-flow news channel; they do not affect discount rates or equity premia. Aggregate credit demand and investment outlays respond significantly to an adverse foreign EPU shock. Corporate investment outlays, payouts, and aggregate credit demand decline in response to such a shock.
