Value stocks are commonly viewed as steady, or conservative. Because you are saving toward your retirement, if you invest in a Value fund, you hope that the fund remains conservative. We would call such a fund "consistent." The funds in this data set have been identified as either being "style consistent" or "style drifter." Out of a sample of 140 funds, 64 were identified as style consistent, while 76 were identified as style drifters. Their statistics for their average return over 5 years are shown below.
