人民大学在职课程培训班网讯：In models of the cross-section of stock returns where some investors over-extrapolatereturns (e.g., Barberis and Shleifer 2003), price momentum and the value premiumboth arise naturally. The key insight from these models is that, to the extent thatmomentum and value are related to the degree of over-extrapolation, the strength andtiming of these patterns will be conditional on how severe over-extrapolation is, withlower (higher) degree of over-extrapolation leading to stronger momentum (value premium). Using the time-series variation in the degree of over-extrapolation documented in Cassella and Gulen (2018), I directly test the hypothesis that both value and momentum stem from over-extrapolation in financial markets. I find that the averagemomentum return is 1.00% (0.10%) per month when the degree of over-extrapolationis low (high), whereas the average value premium is 0.51% (1.29%) per month followinglow (high) levels of over-extrapolation. Furthermore, the degree of over-extrapolationhas different impact on the long and short legs of the portfolios based on differentaggregate market conditions. Overall, my results support the extrapolation-based theories of asset prices, and offer direct evidence about the linkage between some of themost studied asset pricing anomalies and over-extrapolation.
