After the dominant performance of large-cap technology stocks in 2020, concentration concerns naturally come to mind. The HHI, or Herfindahl-Hirschman Index, is a widely-used concentration measure; it’s defined as the sum of the squared index constituents’ percentage weights (usually taken as whole numbers). For example, the HHI for an equally-weighted 50 stock portfolio is 200…

After almost four years of underperformance, we witnessed a change in fortune in February 2021, as the relative performance of the S&P 500® Equal Weight Index turned positive. By the end of April, Equal Weight had outperformed the S&P 500 by 11% over the prior 12 months, as we see in Exhibit 1. Equal Weight’s…
We’ve previously argued that most managers should prefer above-average correlation, because the incremental volatility a manager accepts to pursue an active strategy will be lower when correlations are high. In addition, active managers should prefer above-average dispersion, because stock selection skill is worth more when dispersion is high. Both correlation and dispersion rose in 2020….
Three months ago, we observed that times of severe underperformance for Equal Weight can bode well for future performance. This reflection had become reality by the end of February. After almost four years of underperformance, the S&P 500® Equal Weight Index outperformed the S&P 500 by 1.6% over the past 12 months, as we see…

These two results are reminiscent of the bubble we experienced two decades ago. But the Tech sector of today is not your father’s Tech sector. Similarly, we can analyze the market from a factor perspective and…

First, equities recovered from the depths of March to finish the year strongly, and second, smaller-cap and value stocks staged a roaring comeback in the final quarter.

When we think about reversals in the market, we likely think of brief turnarounds in performance. But what if it’s more? What makes a reversal turn into a recovery is a full-fledged long-term improvement in performance. We can apply this logic to Equal Weight’s recent experience. After consistent underperformance since April 2017, the S&P 500®…
The S&P 500® rose by 10% in the 12 months ending on Oct. 31, 2020, trouncing the S&P 500 Equal Weight Index by 9.1%, as seen in Exhibit 1. While such outperformance is not unprecedented, it does remind us of previous market peaks (especially in December 1999), and raises questions about whether a reversal may…
