One of the guiding mantras of small cap investing has always been that small caps tend to outperform their larger peers over the long-term. While always cyclical, small caps have outperformed large caps over the last several decades. However, in recent years that has all changed. In fact, since 2005, the relative performance between the two share classes has been trendless, with no discernible relationship. This is directly counter to the almost century-long trend that preceded it. One CIO explained the change this way, saying “Market-cap tilts have historically been about catching, and riding, strong and persistent performance waves … Over the last 13 years, in an unconventional fashion, the opportunities to add performance from cap tilts have been relatively small and have required frequent and expert timing”.
FINSUM: Interesting change for small caps. We suspect the change has to do with a combination of the pre-Crisis boom and the extraordinary liquidity thereafter.
