We examine the time variations of expected momentum profits using a two-state Markov switching model with time-varying transition probabilities to evaluate the empirical relevance of recent rational theories of momentum profits. We find that in the expansion state the expected returns of winner...

We construct downside variance risk premiums from the crude oil and gold option data and use them as proxies for market downside uncertainty risks. We find that these downside variance risk premiums contain commodity market specifc pricing information. Further- more, the gold market's exposure...

We examine how the return predictability of deep learning models varies with stocks’ vulnerability to investors’ behavioral biases. Using an extensive list of anomaly variables, we find that the long-short strategy based on deep learning signals generates greater returns for stocks that are...

This paper examines cross-sectional relations between ex ante expected returns and betas. As a proxy for ex ante expected returns, we use implied returns obtained from the risk-adjusted option pricing model suggested in this paper. We find that implied returns have a positive and significant...

We examine whether the results supporting the sentiment-related overpricing story by Stambaugh, Yu, and Yuan (J. Financial Economics, v.104, p.288-302) is still valid after controlling for macroeconomic conditions. We no longer find the results consistent with the sentiment-related overpricing...

This paper specifically examine how the extent of the distress puzzle differs according to the degree of mispricing and short sale constraints. We find that the distress puzzle observed for overpriced stocks, not for underpriced stocks, becomes insignificant after adjustment for short sale...

To explain post-earnings announcement drift, we construct a risk factor related to unexpected earnings surprise, and propose a four-factor model by adding this risk factor to Fama and French's (1993), (1995) three-factor model. This earnings surprise risk factor provides a remarkable improvement...

This paper evaluates and compares asset pricing models in the Korean stock market. The asset pricing models considered are the CAPM, APT-motivated models, the Consumption-based CAPM, Intertemporal CAPM-motivated models, and the Jagannathan and Wang conditional CAPM model. By using various test...
