ABSTRACT This study examines the capital market implications of common investor relations (IR) representation, a phenomenon in which multiple public firms share the same external IR representative. Using a difference‐in‐differences research design, I document that common IR representation is associated with greater overlap in institutional ownership and sell‐side analyst coverage as well as similarities in disclosure practices among clients—even those operating in different industries. These effects culminate in heightened return comovement among firms sharing IR representation. My findings provide insight into the role of IR companies as capital market gatekeepers and suggest that when a firm outsources its IR function, the IR company influences its capital market connectivity.

We survey corporate managers of both guiding and non-guiding firms. We find that managers of firms that provide guidance say that they: (1) primarily provide guidance to satisfy analyst and investor demands and manage analysts’ earnings expectations; (2) are relatively unconcerned about proprietary or litigation costs (managers of non-guiding firms are more likely to see litigation risk as a concern); (3) predominantly issue guidance that is conservative relative to their internal expectations; (4) are concerned that guidance induces analysts and investors to focus on the short-term but not that it induces managers themselves to make myopic decisions internally. We also find that managers are miscalibrated about the accuracy of their guidance and that significant quantities of guidance that managers say their firms issue are not captured by conventional sources. We offer several other new insights relevant to the voluntary disclosure literature.
