MaxEnt-Based Explanation of Why Financial Analysts Systematically Under-Predict Companies' Performance

Vladik Kreinovich, Songsak Sriboonchitta

Abstract


Several studies have shown that financial analysts systematically under-predict the companies' performance, so that quarter after the quarter, 70-75% of the companies outperform these predictions. This percentage remains the same where the economy is in a boom or in a recession, whether we are in a period of strong or weak regulations. In this paper, we provide a possible Maximum Entropy-based explanation for this empirical phenomenon -- an explanation rooted in the fact that financial analysts mostly analyze financial data, while to get a more accurate prediction, it is important to go deeper, into the technical issues underlying the companies functioning.
