Stock Market Internals Earnings Momentum, Small/Mid/Large Caps, Growth/Value/Cyclicals, and Additional Factors
Small Cap Discount = 22%
Using non-normalized trailing operating earnings, Small Caps are selling at a 22% valuation discount to Large Caps, as illustrated in the chart. Since the market lows in March, we’ve seen a steady uptrend in Small Cap performance (Russell 2000 +55%, S&P 500 +46%). However, the valuation gap between the two flavors remains historically very wide, thanks to the previous four years of Large Cap outperformance. Based on full-year 2021 earnings estimates (see table), Small Caps are also at a 22% discount to Large Caps.
In August, the S&P 500 notched its fifth consecutive monthly gain with the five largest firms accounting for nearly half of its 7% advance. Those companies are now within spitting distance of comprising 25% of the index—that’s a doubling of market cap for the five largest firms in just under three years.
