Time-Varying Skewness in Stock Returns: An Information-Based Explanation
MetadataShow full item record
There is evidence of regularities in the skewness of asset returns reported in the literature. The literature, however, offers no adequate explanations for these phenomena. Based on a simulation approach, we provide evidence that at least some aspects of skewness can be explained in terms of extant information-based theories in finance. Using a well-accepted model for generating asset returns, we demonstrate that when the effects of the uncertain information hypothesis and Kahneman and Tversky's prospect theory are incorporated in the return-generating process, the resulting return distributions can show negative skewness and variations of skewness with changing economic climates similar to what has been observed in empirical distributions.
