  • We study the portfolio selection of large investors who own equity of the firms competing in a symmetric oligopoly. An investor's objective is to maximize the value of its portfolio accounting for the impact of its interests on the managerial incentives. We show that in a stationary equilibrium the portfolios of large investors soften competition, increasing the price markup and profits.
