Addressing Valuation Risk By Rebalancing

Addressing Valuation Risk By Rebalancing

Addressing Valuation Risk By Rebalancing by Tripp Zimmerman, Associate Director of Research, The WisdomTree Blog

With equity markets up more than 250% since the 2009 lows and slightly off all-time highs1, we think it is especially important to ask whether the underlying fundamentals justify these moves. We also think it is important to be mindful of how an annual rebalance, steering a portfolio back to an underlying fundamental such as dividends, can help manage valuation risks—a key factor in the inclusion of non-cap-weighted indexes in the “smart beta” category of indexes.

Quantifying the Fundamental Rebalance

With market capitalization-weighted indexes, when constituents increase in price compared to other stocks, they gain greater weight and increase their impact on the performance of the index.

Despite 60% Loss On Shorts, Yarra Square Up 20% In 2020

Yarra Square Investing Greenhaven Road CapitalYarra Square Partners returned 19.5% net in 2020, outperforming its benchmark, the S&P 500, which returned 18.4% throughout the year. According to a copy of the firm's fourth-quarter and full-year letter to investors, which ValueWalk has been able to review, 2020 was a year of two halves for the investment manager.

WisdomTree Dividend Indexes employ a rules-based rebalancing mechanism that adjusts relative weights based on underlying dividend trends. During the rebalancing process, which occurs once per year for each Index, the relationship between price change and dividend growth is measured. In figure 1, we quantify the dividend growth for companies that received an increase in weight or a decrease in weight and compare that to the overall universe2.

  • Dividend Growers Saw Weight Increase: The companies that saw their weight increase at the rebalance had a median dividend growth of 9.7%, which was greater than the median dividend growth of all companies (at 6.6%). Companies that saw their weight lowered at the rebalance had a median dividend growth of just 5.2%.
  • Underperformers Typically Saw Weight Increase: Performance is also a key driver of relative changes. The typical stock that saw its weight increase had a median total return that was more than 16 percentage points lower than the median of all stocks.
  • Outperformers Reduced at Rebalance: The typical stock that saw its weight lowered at the rebalance had a median total return 9.6 percentage points above all stocks. This is one of the keys to managing valuation risks.

A Detailed Look at the Individual Drivers

The above was a higher-level overview of the total Index, but in figure 2, we highlight a few of the top individual additions and deletions to further specify the contributors. There weren’t any major shifts in sectors at this year’s rebalance, with no sector receiving an increase or decrease of more than 0.8%.

  • Financials Led Dividend Stream Growth: Over the period, the Financials sector displayed the strongest percentage growth at 13%, earning the sector a 0.4% increase in weight in WTDI. American International Group (AIG) and Citigroup both saw their weights increase over the period after significant dividend-per-share increases of 120% and 400%, respectively. The Financials sector’s dividends are still recovering from their collapse, and it remains the only sector below 2007 dividend levels.
  • Energy Earned Largest Increase: The biggest increase in weight for any sector in WTDI occurred in Energy—an increase of 0.7%, which was driven primarily by its poor performance over the period. Although the aggregate dividends for the sector slightly contracted, that contraction wasn’t as bad as the sector’s price contraction over the period, ultimately improving the sector’s relative valuation.
  • Industrials and Information Technology Saw Their Weight Lowered: The biggest decreases in weight for WTDI occurred in the Industrials and Information Technology sectors—a decrease of 0.7% and 0.6%, respectively. As noted in figure 2, General Electric and Microsoft helped contribute to this decrease in weight, having grown their dividends more slowly than their prices over the period, thus ultimately decreasing the fundamental relationship between price and dividends.

Importance of Incorporating a Relative Rebalance

The WisdomTree annual rebalance is a key element of the added value of WisdomTree’s Index methodology and can help manage valuation risks. WisdomTree Indexes use dividend growth as a key factor in determining which companies get increased weight at a rebalance. We interpret another year of above-average dividend growth as a positive indicator of underlying market fundamentals and believe it helps provide a notable foundation for potential future gains.
