We examine the relation between institutions' investment horizons on firms' financing and investment decisions. Firms with larger short‐term institutional ownership use less debt financing and invest more in corporate liquidity. In contrast, firms with larger long‐term institutional ownership use more internal funds, less external equity financing, and preserve investments in long‐term assets. These results are primarily driven by the variation in informational preferences of different institutions. We argue that short‐term (long‐term) institutions collect and use value‐neutral (value‐enhancing) information.
