内 容:The security market line is often flat or downward-sloping. We hypothesize that probability weighting plays a role and that one ought to differentiate between periods in which agents overweight extreme events and those in which they underweight them. Overweighting inflates the probability of extremely bad events and demands greater compensation for beta risk, whereas underweighting does the opposite. Unconditional on probability weighting, these two effects offset each other, resulting in a flat or slightly negative return-beta relationship. Similarly, overweighting the tails enhances the negative relationship between return and coskewness, while underweighting reduces it. We derive a three-moment conditional CAPM model for a market with rank-dependent utility agents to make these predictions, and we support our theory through an extensive empirical study.
