We test the predictions of the three main behavioral finance theories of market under- and overreaction using out-of-sample data conditional on the nature of the news using the going-concern audit opinion (bad news event) and its withdrawal (good news event). We find strong support for the Daniel, Hirshleifer and Subrahmanyam (1998) model for our bad news as well as the good news case suggesting that market underreaction to going-concern opinions is a consequence of prior market overreaction resulting from incorrect classification of going-concern firms by investors into trending regimes. In contrast, we find no support for the Barberis, Shleifer and Vishny (1998) or Hong and Stein (1999) models in our event-study setting in either the bad or good news cases. Our results have a number of implications relating to the value of such theoretical behavioral finance models in practice. We also highlight the central role of the limits-to-arbitrage assumption when testing such behavioral finance theories.

Keywords: finance, under- and overreaction models, limits to arbitrage, going-concern
