Composite Scores and Future Returns for Subsamples of High and Low BM
Firms
Table 5 and 6 report portfolios of a subsample of high BM formed based on VSCORE
and GSCORE, respectively. Panel A (Panel B) of each table shows the one-year (two-year)
investment horizon. Similar to results for all sample firms, our results for a subsample of
high BM firms indicate that higher score firms earn more positive subsequent abnormal
returns than do lower score firms. Specifically, for VSCORE, the mean (median) of one-year
MAR for the high and low group is 24.09% (12.97%) and 5.39% (-3.82%), respectively.
Consequently, a mean (median) return difference (High – Low) is 18.70% (16.78%),
respectively. Similarly, for two-year MAR, the mean (median) for the high and low group is
50.27% (35.11%) and 18.71% (3.89%). As a result, a mean (median) return difference (High
– Low) is 31.56% (31.22%). Results for VSCORE are consistent with Piotroski (2000).
For GSCORE, the mean (median) of one-year MAR for the high and low group is
26.08% (18.49%) and 14.64% (1.64%), respectively, resulting in a significant return
difference (High – Low) of 11.44% (16.85%) and the mean (median) of two-year MAR for
the high and low group is 46.40% (32.42%) and 22.48% (3.38%), resulting a significant
return difference (High – Low) of 23.92% (29.04%). Consistent with results for all sample
firms, our results for high BM firms suggest that VSCORE and GSCORE can also be used to
predict future stock returns and a zero-investment portfolio of longing high score stocks and
shorting low score stocks earn significant positive future returns.
