GAAP versus The Street: An Empirical Assessment of Two Alternative Definitions of Earnings

Managers, security analysts, investors, and the press rely increasingly on modified definitions of GAAP net income, known by such names as "operating" and "pro forma" earnings. We document this phenomenon and discuss competing explanations for the recent rise in the use of such modified earnings numbers and implications for the interpretation of related accounting research. Our results show that over the past 20 years there has been a dramatic increase in the frequency and magnitude of cases where "GAAP" and "Street" earnings differ. Further, there is a very strong bias toward the reporting of a Street earnings number that exceeds the GAAP earnings number. We also show that the market response to the Street earnings number has displaced GAAP earnings as a primary determinant of stock prices. Finally, through an analysis of earnings releases, we show that management has taken a proactive role in defining and emphasizing the Street number when communicating to analysts and investors.

Convergent cultural evolution and multilevel selection: Reply to comments on Janet Landa’s ‘The bioeconomics of homogenous middleman groups as adaptive units: Theory and empirical evidence viewed from a group selection framework’

The comments on Janet Landa’s (J Bioecon 10(3):259–278, 2008) target article provide a fascinating snapshot of how multilevel selection theory is perceived across several disciplines. When we focus on the zone of agreement among the commentators, Landa’s article provides an important example of convergent cultural evolution. When we focus on the zone of disagreement, we find a snapshot of the current status of the group selection controversy that goes beyond narrow scientific issues and requires a ‘truth and reconciliation’ process to resolve, as discussed in my series of blogs titled “Truth and Reconciliation for Group Selection” (Wilson , 2009) and briefly summarized here.      

Investor recognition and stock returns

It is well established that investment fundamentals, such as earnings and cash flows, can explain only a small proportion of the variation in stock returns. We find that investor recognition of a firm’s stock can explain relatively more of the variation in stock returns. Consistent with Merton’s (J Finance 42(3):483–510, 1987) theoretical analysis, we show that (i) contemporaneous stock returns are positively related to changes in investor recognition, (ii) future stock returns are negatively related to changes in investor recognition, (iii) the above relations are stronger for stocks with greater idiosyncratic risk and (iv) corporate investment and financing activities are both positively related to changes in investor recognition. Our research suggests that investors and managers who are concerned with firm valuation should consider investor recognition in addition to accounting information and related investment fundamentals.
