We hypothesize that post-earnings-announcement drift (PEAD) is caused by underreaction of long-term investors since they do not pay much attention to short-term events. Consistent with the hypothesis, empirical observations show that stocks mostly held by long-term investors exhibit strong PEAD,...

This study examines the effect of changes in the KOSPI 200 index to determine the main cause of abnormal return behavior. It tests five prevailing hypotheses individually and simultaneously using both added and deleted stocks during the event window. We find evidence of permanent price effects...

The dynamic nonmyopic portfolio behavior of an investor who trades a risk-free and risky asset is derived for all HARA utility functions and a stochastic risk premium. Conditions are found for when the investor holds more or less than the myopic amount of the risky asset; hedges against or...

This paper examines the relative risk of good-news firms, i.e., those with high standardized unexpected earnings (SUE), and bad-news (low SUE) firms using a stochastic discount factor approach. We find that a stochastic discount factor constructed from a set of basis assets helps explain...

We develop a conditional version of the consumption capital asset pricing model (CCAPM) using the conditioning variable from the cointegrating relation among macroeconomic variables (dividend yield, term spread, default spread, and short-term interest rate). Our conditioning variable has a...

This paper reexamines, at a range of investment horizons, the asymmetric dependence between hedge fund returns and market returns. Given the current availability of hedge fund data, the joint distribution of longer-horizon returns is extracted from the dynamics of monthly returns using the...

This paper examines the equilibrium relation between future labor income growth and expected asset returns; it proposes revisions in the expectation of future labor income growth as a macroeconomic state variable and suggests a three-factor model, including a factor related to this variable,...
