Abstract:     
This paper provides an empirical, behaviorally-based approach to estimating and interpreting pricing kernels. Pricing kernels are decomposed into a sentiment component and a fundamental component, which are estimated from option and stock prices. Our estimates correlate well with independent sentiment measures such as the Baker-Wurgler index, and also with independent empirical estimates of risk aversion and time preference. Our analysis points out two significant issues related to overconfidence. First, the Baker-Wurgler index strongly reflects excessive optimism but not overconfidence. Second, the dynamics of optimism and overconfidence generate a perceived negative risk-return relationship, while objectively the relationship is positive.
