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….

Last week S&P Dow Jones Indices released its SPIVA® U.S. Year-End 2020 Scorecard. As has been the case for 17 of the past 20 calendar years, the majority of active large-cap managers underperformed the S&P 500®. Performance was better for mid- and small-cap managers, as Exhibit 1 shows. What caused the advantage for smaller-capitalization strategies?…
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…
For at least five years, we’ve noticed that, despite historical performance, active managers regularly proclaim that this year will at last be the time when active management shows its value. I suspect that most advocates of indexing derive at least some guilty pleasure from observing this ritual. (I know I do.) So, we want to…
Recent headlines have reflected the extraordinary behavior of GameStop Corp.; the company’s stock rose from $18.84 at year-end 2020 to $325 at the close on Jan. 29, 2021, then declined to $90 in the first two trading days of February. At year-end, GameStop was the 314th largest stock in the S&P SmallCap 600®. By the…
Information Technology was the top-performing sector in 2020, up 44%, while Momentum (up 28%) was the second best-performing factor. 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…
Early in 2020, global stock markets acted in concert during the sell-off, bottoming out around the world in late March. However, the extent to which different markets declined, and the strength of the subsequent recovery, differed significantly around the world. With 2020 now in hindsight, S&P DJI’s range of global equity indices tell a tale…
Investment management is a zero sum game. The source of outperformance for a market’s outperformers is the underperformance of the same market’s underperformers. Properly measured, the weighted average sum of the winners’ gains is exactly equal (before costs) to the weighted average sum of the losers’ losses. This identity, along with the professionalization of the…
The contrasts between the first 10 months of 2020 and the month of November were vivid. Consider: At the end of October, the year-to-date total return of the S&P 500® was barely positive (2.77%), but was well ahead of the returns of the S&P MidCap 400® (-6.63%) and the S&P SmallCap 600® (-13.06%). In November,…
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…
