At WisdomTree, we believe strongly in relative value rebalancing
. The act of rebalancing constituents of an index back to their fundamental
values is important, given our belief that stocks often overshoot their underlying fundamentals. Consequently, investors run the risk of paying too much for stocks that have become more expensive compared to their fair value
. A disciplined strategy of reweighting allocations back to attractively valued stocks, through the annual rebalance process, is an important element in managing market valuation risks
Below we start with a discussion of how the Earnings Stream
grew between the 2014 and 2015 Index screening dates
—as the Earnings Stream
is the key factor that drives exposures in the WisdomTree Earnings Index
Figure 1: Gauging the Earnings Stream over Time (as of 11/30/15 Index Screening)
• Negative Earnings Stream Growth in 2015:
The Earnings Stream
contracted 4.3% in 2015, driven by the decline of earnings in the Energy and Materials sectors. Although aggregate earnings declined, the broad market is still relatively healthy, with more than 2,000 profitable companies whose Earnings Stream
total $1.09 trillion. If you remove the Energy sector, the Earnings Stream
would have grown 1.31% over the period.
• Financial Earnings Make New High:
Before the financial crisis and as of the 2007 Index screening, the Financials sector’s Earnings Stream
was $248 billion. At the bottom, the 2009 Index screening, the Financials sector’s earnings had collapsed by about 70% to just $72 billion. As one sign the financial companies are moving beyond the crisis, the earnings of the Financials sector at this rebalance were $260 billion, up 6.6% on the year and now 4.8% above the previous all-time high. The Financials sector exhibited the highest earnings growth on both a dollar and percentage basis over the period.
• Information Technology Leaders:
The Information Technology sector saw its U.S. Earnings Stream
grow the fastest over the last eight years, doubling earnings from 2007 through 2014. As a result, the Information Technology sector saw its percentage of total earnings grow from 11.3% to 19.0%, and it now represents the second most profitable sector.
The growth in earnings is an important element of the annual rebalance. The other critical factor is stock price performance. Rebalancing back to the Earnings Stream
forces a discipline to sell stocks that have become more expensive—in other words, selling stocks that have appreciated compared to their earnings.
Figure 2: WisdomTree Earnings Index Rebalance Trends (as of 11/30/15)
• Companies Growing Their Earnings Saw Weight Increase:
The companies that saw their weight increase at the rebalance had a median earnings growth of 17.5%, which was greater than the median earnings growth of all companies (at 0.2%). Companies that saw their weight lowered at the rebalance had a median earnings contraction of 22.7%.
• 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 2.5 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 that was 3.6 percentage points above all stocks. This is one of the keys to managing valuation risks.
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’s Earnings Indexes use earnings growth as a key factor in determining which companies get increased weight at a rebalance. We think the aggregate earnings decline may act as a reminder of why it is important to focus on fundamentals and incorporate a relative value rebalance in the investment process.
