The deficient-GAAP argument takes the major objective of financial
reporting to be ‘‘the prediction of future investor cash flows or stock returns’’
(Lev, 1989, p.157)
Proponents of the deficient-GAAP argument therefore use
the return–earnings correlation as a measure of GAAP’s success in fulfilling its
objective.The maintained hypothesis is that capital markets are informationally
efficient and the major objectives of financial reporting are generally
inferred from the FASB’s Statements of Financial Accounting Concepts
