A Brief Summary of the Paper and Its Contributions
The key point of the paper by John R. M. Hand and Jeremiah Green (2011)
is to demonstrate that portfolio performance can be improved considerably by
optimally incorporating accounting information. The stated goal of the authors is
to study the importance of accounting information from the perspective of a portfolio
manager. They are not particularly interested in demonstrating the importance
of accounting information for firm valuation (the fundamental analysis
viewpoint adopted by many authors like Penman [2009]), or the prediction of
future abnormal returns (as in Bernard &Thomas [1989, 1990], and many others).
