Disclosure Policies in Quarterly Earnings Guidance


Prof. Michael TANG

Assistant Professor of Accounting, Stern School of Business, New York University



We examine whether differences in guidance patterns reflect differences in disclosure policies by comparing guidance issued by firms that provide “regular” guidance every quarter (over twelve consecutive quarters) to firms that provide guidance sporadically. We find that regular guidance tends to be accurate and have less variable forecast errors. We also find that market participants view regular guidance more credibly than sporadic guidance. Additional results suggest that firms that provide regular guidance are responding to a heightened demand for disclosure from institutional investors, whereas firms that provide guidance sporadically seem to tradeoff the benefits of lowering overly optimistic earnings expectations against the costs of large forecast errors when deciding whether to issue guidance in a particular quarter. Together, we document systematic differences in the quality and credibility of guidance between firms that provide guidance regularly and firms that provide guidance sporadically, suggesting that these firms likely have distinct objectives for issuing guidance.
