We examine the impact of positive skewness on asset prices using CAPM experiments. Contrary to the predictions of expected utility models but consistent with prospect theory, our findings reveal that skewed assets available in small supply exhibit negative excess returns. In line with prospect theory models, we show that the negative excess return of the positively skewed asset is most pronounced in market sessions in which traders overweight the low probability of receiving a large payoff.
