Abstract
This paper studies the impact of product market competition on the well-documented positive relation between firms' current profitability and future stock returns. I find that this relation is robust only in competitive industries. A long-short portfolio sorted on profitability earns an average monthly return of 1.1% in competitive industries and only 0.14% in concentrated industries. Firms' differential exposure to investment-specific technology shocks explains this gap. To understand this result, I build a production-based model with imperfect competition. Market power reduces a firm's investment response to these shocks and thus lowers risk exposure. Empirical tests confirm the model's predictions.
