The Relationship between Institutional Common Ownership, Marketing, and Firm Performance Abstract The growth in institutional holdings of public firms has led to increased interest in the concept of common ownership, in which the same investor owns stakes in multiple firms within the same industry. Economic theory suggests that common ownership could affect firm performance, but little empirical research has examined the nature of this effect or how a firm’s extant marketing potentially relates to this effect.
