EFF/KRF: Yes, but not with lots of confidence. The market return tends to be lower when aggregate ratios like E/P and D/P are low, and vice versa. The economic logic is based on the same discount rate effect we use to explain the higher expected return on value stocks. The empirical evidence leans toward a positive relation between aggregate fundamental to price ratios and future market returns, but there is lots of uncertainty about the forecast.
