WebbUnfortuna2 tely, Shanken’s EIV-corrected standard errors are consistent only under the restrictive assumptions of no conditional heteroskedasticity and no conditional autocorrelation in asset returns (given factors). Because these assumptions are often3 disputed in empirical studies, Shanken’s EIV adjustments could produce potentially biased WebbIn addition, though these t-statistics become small, they remain significant after using Shanken correction. The estimated slope coefficients are not significantly different from zero for the majority of scaled models, indicating that the time-varying component of the intercept is not an important determinant for the cross-section of average returns.
WebbThese results are unaltered after incorporating the Shanken correction factor that addresses the error-in-variables problem inherent in CSR. Further tests also show that, in the short run, factors other than risk explain the cross section of asset returns and that the relationship between return and risk may not be linear. Webband Ritter (1992), and Ball, Kothari, and Shanken (1995) in evaluating the apparent profitability of the contrarian investment strategy (see e.g., DeBondt and Thaler (1985, 1987)). In particular, Ball, Kothari, and Shanken (1995) show that there are no significant abnormal returns for a June-end initiated strategy after adjusting for beta risk.
