Managing Valuation Risk by Rebalancing by Jeremy Schwartz, Director of Research, The WisdomTree Blog
With equity markets forging new all-time highs, we think it is especially important to ask whether these moves are justified by the underlying fundamentals. 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.
Is there a link between intelligence, knowledge and successful investing? At first glance, it might appear as if there is. Wall Street is known for only hiring the best and brightest. However, some of the world’s most successful investors didn’t attend the world’s best universities and don’t claim to have a higher than average I.Q. Read More
WisdomTree 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 increases in weight or decreases in weight and compare that to the overall universe.1

• Dividend Growers Saw Weight Increase: The companies that saw their weight increase at the rebalance had a median dividend growth of 13.3%, which was greater than the median dividend growth of all companies (at 8.0%). Companies that saw their weight lowered at the rebalance had a median dividend growth of just 4.5%.
• 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 over 8 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 13 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 additions and deletions to further specify the contributors.

• Energy Earned Largest Increase: The biggest increase in weight for any sector in WTDI occurred in Energy—an increase of 1.7%, which was driven primarily by its poor performance over the period. As figure 2 shows, Exxon and Chevron contributed to this increase in weight, having grown their dividends faster than their prices over the period, ultimately improving the fundamental relationship between price and dividends.
• Financials Led Dividend Stream® Growth: Over the period, the Financials sector displayed the strongest percentage growth, earning the sector a 1.3% increase in weight in WTDI. Bank of America saw the largest increase in weight in the sector after increasing its dividend per share fivefold over the year, from $0.01 to $0.05, which translated to a Dividend Stream growth of almost 400%.
• Information Technology Saw Its Weight Lowered: The biggest decrease in weight for any sector in WTDI occurred in Information Technology—a decrease of 2.4%, which was driven primarily by its strong performance over the period. As noted in figure 2, Apple, Intel and Microsoft all 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 double-digit dividend growth as a very positive indicator of underlying market fundamentals and believe it helps provide a notable foundation for potential future gains.
