Piotroski (2000) suggests that his composite score is appropriate for high BM firms. This paper then examines whether the score is associated with future stock returns for subsamples of high BM firms. Firms with BM ratio above 70th percentile are classified as high BM firms. Consistent with results for our full sample, our empirical results for high BM firms show that portfolios of stocks with higher score earn higher one-year and two-year market-adjusted buy-and-hold returns than do those with lower score without additional risk and zero-investment portfolios of longing high score stocks and shorting low score stocks earn significant positive market-adjusted returns.
