The Case for Equal Weight Indexing

2020 witnessed outperformance from some of the largest S&P 500® companies as investors expected these firms to be better placed to navigate the COVID-19 environment. Exhibit 1 shows that this outperformance led to the largest names accounting for an unusually high proportion of the U.S. large-cap equity benchmark, and therefore having a bigger impact on…

Motions of the Market

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…

Understanding the ESG Consequences of Factor-Based Investing: Part 2

    In our previous blog, we looked at the S&P Factor Indices’ ESG exposures, showing that factor exposures can have an influence on ESG scores.

Surprising but Explainable

Equal-weight indices have a small-cap tilt. Therefore, one might naturally assume that the volatility of equal-weight indices is higher than that of their cap-weighted counterparts. Surprisingly, this is not always the case, and we can understand why using the lens of dispersion and correlation. Exhibit 1 shows that the volatility of the S&P 500® Equal…

Investing in a World of Unknown Future Outcomes: The Benefits of Equal Weighting

Consider this thought experiment: You “know” that 499 of the companies in the S&P 500® will return exactly 5% next year. One will return 100%. You have no way to determine which stock will be the big winner, or to know or infer anything about its characteristics. You can invest in either a cap-weighted S&P…

Explaining Equal-Weight Indices

Our recent paper explores the characteristics and applications of equal-weight indices from various standpoints. Since a number of equal-weight indices have outperformed their corresponding cap-weighted parents over the past 15 years, one of the most interesting perspectives asks if factors can help to explain the excess returns of equal weight.  Which factors are most relevant?…

Security Selection & Sector Allocation Effects of Equal Weighting the S&P 500®

Constituents of the S&P 500 Equal Weight (EW) and S&P 500 are identical, but the EW version is rebalanced quarterly so that every company has equal representation after the rebalance.  That often results in significantly different performance between the two indices, because equal weighting gives more representation to smaller stocks and alters the distribution of…
