The Barron’s 400 Index Excels in 2021, Outpacing U.S. Equity Benchmarks


The Barron’s 400 Index (B400) delivered its best annual performance in eight years with a 31.4% total return in 2021, outdoing virtually every major U.S. equity benchmark, including the S&P 500 Index. This was B400’s best return since 2013, when the index gained 41.6%, also outperforming the broad U.S. market. An index B400 did not outperform in 2021 was its market cap-weighted sibling (B400 MCW), which gained 33.1%, also on a total return basis (we’ll be writing more about B400 MCW in upcoming posts, so please stay tuned). Figure 1 shows B400’s 2021 cumulative total return compared to large, mid, and small cap U.S. equity benchmarks as well as the popular Nasdaq 100 Index.

B400’s performance in 2021 extended a remarkable run that started following the brief bear market suffered by U.S. equities during the first quarter of 2020 as the Covid-19 pandemic overtook global markets in what proved to be a short-lived drawdown. Between Dec. 31, 2019, and March 23, 2020, the market’s low point for the year, B400 lost 37.6%, on par with the 37.4% decline suffered by the equal weighted version of the S&P 500 Index (both figures based on total returns). However, from the March 2020 low through the end of 2021, B400 rallied 149.1%, outperforming both versions of the S&P 500 Index, the small and midcap indexes, and even the technology-laden Nasdaq 100, as illustrated in Figure 2. While the latter holds many of the large technology names that benefited from the pandemic-induced work-from-home trend, B400 more than held its own in no small part thanks to its broad exposure to solid companies in cyclical industries that were well positioned to benefit from a resurgence in U.S. economic activity. Figure 3 illustrates the sector breakdown for the 711 companies held by the B400 during calendar year 2021.

Breaking Down the Companies

The B400 Index reconstitutes and rebalances in March and September, which means that over a full calendar year B400 holds three different ‘portfolios.’ The first portfolio of 400 companies is the one that it starts the calendar year with (which was reconstituted in September of the previous year), which is held through the March rebalance. When the Index reconstitutes in March, this determines the year’s second 400-company portfolio, which it then holds through its September reconstitution and rebalance. Finally, when the B400 reconstitutes in September, the third portfolio of companies it holds in the year is determined.

During 2021, the three portfolios that were held by BFOR comprised a total of 711 different companies, including the 400 companies selected by the B400 in September 2020, March 2021, and September 2021. Thirty-six (36) of these were selected twice after having skipped the middle period between March and September; counting these as separate holdings, the B400 held a total of 747 positions in 2021. Of these, 73% (or 542 holdings) had a positive return during their time as members of the B400, while only 27% (or 205 holdings) posted a negative return . It’s worth noting that 137 companies that were members of the B400 at the start of the year (selected at the September 2020 rebalance) are still part of the index (34% of current constituents). Figure 4 summarizes the number of companies that were members of the B400 across different time periods during 2021.
