小盘股跟标普500比不算太贵 The Russell 2000's 2x enterprise value-to-forward sales multiple indicates significant re-rating from March's 1.4x low, but is a far cry from the 2.2x the index commanded at the end of January. Relative to the S&P 500, the small-cap gauge trades at a 35.3% discount vs. the 22.3% average discount over the past 12 years -- good for 1.9 standard deviations below norms.
