This paper investigates the performance of the contrarian investment strategy using the CAPM and APT. The results from multivariate tests of structural changes based on the CAPM show that the systematic risks of contrarian portfolios are not stable over time. In addition, the mean-variance...

This paper proposes tests of unconditional mean-variance efficiency using bootstrap method that does not depend on specific distributional assumptions. We reject the mean-variance efficiency of the CRSP value- weighted stock index for five of the seven consecutive ten-year subperiods from 1926...

By applying Bai and Perron's [Bai, J., Perran, P., 1998. Estimating and testing linear models with multiple structural changes. Econometrica 66, 47-78] change-point model, we pinpoint the exact dates for structural breaks in the book-to-market premium. We find that overall the BM premium is...

Based on a Markov chain Monte Carlo method, namely the Gibbs sampler, a simple approach is proposed to compare the potential performances between two sets of securities. The maximum attainable Sharpe measure is used to measure the potential performance of a set of securities. The procedure is...
