We construct a dynamic inter-industry network using a comprehensive sample of media news to examine how news travels across industries. Our analyses show that cross-industry news contains valuable information about firm fundamentals that is not fully captured by firms' own news or within-industry peers' news. Stock prices do not promptly incorporate cross-industry news, generating return predictability. Underreaction to cross-industry news is more pronounced among smaller stocks that are more illiquid, more volatile, and have fewer analysts following. A long-short strategy exploiting cross-industry news yields annual alphas of over 10%.
