The following post comes to us from Nicholas Seybert of the Department of Accounting & Information Assurance University of Maryland, and Holly Yang of the Accounting Department at the University of Pennsylvania.
In our paper, The Party’s Over: The Role of Earnings Guidance in Resolving Sentiment-driven Overvaluation, which was recently made publicly available on SSRN, we show that an important link between investor sentiment and firm overvaluation is optimistic earnings expectations, and that management earnings guidance aids in resolving sentiment-driven overvaluation. Understanding the underlying process linking investor sentiment to overvaluation provides insight into investor psychology and difficult-to-predict bull and bear markets. Currently, there are multiple possible explanations for why uncertain stocks are overvalued during high sentiment periods. For example, investors may exhibit different preferences, such as reduced risk aversion, during high sentiment periods, which would lead them to overpay for stocks with high valuation uncertainty. Under this scenario, in subsequent months, a general shift in investing trends or psychology would lead to the gradual decline in prices. Alternatively, investors may engage in a more detailed thought process that involves unrealistic expectations of future firm earnings, where there is more potential to overestimate future earnings for uncertain firms. Under this scenario, in subsequent months, revisions in earnings guidance or other earnings news released by the overvalued firms should lead to predictable price declines. We focus on the second explanation, examining management earnings guidance to test the extent to which the correction of earnings expectations mitigates the overvaluation problem.
