Earlier we wrote about managing valuation risks in the domestic small-cap market by focusing on profitable companies and rebalancing back to fundamentals.We thought it would be useful to expand on how screening and weighting by profitability can also help manage valuation risk in mid-caps.
WisdomTree feels that weighting by market capitalization, which does not weight, consider or rebalance back to any fundamental value, may not be the best approach. Instead, we believe a disciplined strategy of anchoring allocations back to a concept of relative value, based on fundamentals such as dividends or earnings, can add value over time.
The Fundamental Difference
The WisdomTree Earnings Indexes seek to provide exposure to the core, profitable market but do so while maintaining sensitivity to valuation. To help achieve this, WisdomTree weights companies in the Indexes by the profits they generate, rather than their market cap, and rebalances back to profitability on an annual basis.
WisdomTree’s Earnings Index rebalance process typically is driven by:
-Earnings Growth: Companies increasing profits see their weight increased
-Underperformers typically see their weight increased
-Outperformers often see their weight decreased
This process tends to shift weight to firms with lower price-to-earnings (P/E) ratios, as illustrated in the chart below: it compares the distribution of stocks by their P/E ratios in the WisdomTree MidCap Earnings Index to that of widely followed market cap-weighted indexes.
P/E Ratio and Weight Distribution
The P/E ratio for the WisdomTree MidCap Earnings Index is approximately 16.4x, about 15% lower than the 19.4x P/E ratio of the S&P MidCap400 Index and 16% lower than the 19.7x P/E ratio of the Russell Midcap Index.1 The chart below provides a look at how the weight is distributed, to give a sense for why this lower P/E ratio is seen at the aggregate index.
