This paper examines how and how well do leading economists forecast stock market returns. This question is fundamental in finance, since the Capital Asset Pricing foundation rests upon assumptions about the properties of investors' expectations for stock market returns. The results reveal that economists' expectations of market returns as exemplified in Livingston's data do not meet the necessary conditions of efficiency. It should be noted however, that in later period some improvement in the quality of economists' forecasts was observed.
