In our view, this recent widening in multiples has several implications. First, diverging valuation multiples between cheap and expensive stocks are inconsistent with the concern that the value premium may have been arbitraged away as a result of it being so well known and due to substantial funds being invested in value strategies. Were this the case, it would be reflected in a narrowing valuation spread over time instead of the widening trend we have witnessed. Therefore, it is highly unlikely that arbitrage activity was the driver of the recent underperformance of value strategies.
Second, diverging valuation multiples suggest that return prospects for value are currently high. The widening of the valuation spread in the late 1990s was followed by mean reversion in the early 2000s, which resulted in the massive outperformance of cheap stocks over their expensive counterparts.
Third, the net spread widening that occurred over our full sample period means that realized returns might even underestimate the true magnitude of the value premium over this period.2
Value investing remains very attractive from a valuation perspective
When we look at the recent developments in Figure 1, we do see that the value spread has shrunk slightly in 2021. However, it remains considerably wide compared to historical levels, still above the 97th percentile. Therefore, we believe that value investing remains very attractive from a valuation perspective.
One question that remains is that maybe ‘this time is indeed different’ and value stocks deserve to be cheaper than historically observed. Maybe expensive companies (based on simple valuation multiples) could be much more profitable today than in the past (compared to the dot-com bubble, for example), or their expected long-term growth could be much higher.
Figure 2 shows the spread in operating performance (proxied by gross profitability, GP/A)3 between cheap and expensive companies. On average, cheap stocks – according to the enhanced value strategy – display about the same levels of profitability as expensive ones, at a global level.4
Admittedly, cheap stocks have been less profitable between 2017 and 2020. However, their profitability has improved considerably in recent months. In fact, cheap stocks were actually slightly more profitable than their expensive peers at the end of March 2021. Therefore, the current valuation spread cannot be justified by differences in profitability.
Moreover, current profitability is mainly backward-looking, so what about future growth expectations? If profitability levels are the same as those in the present day, then stocks with higher expected growth should trade at higher valuations.
Cheap stocks tend to have lower future growth expectations than expensive ones, which explains why the latter are also called ‘growth stocks’. However, relative growth expectations are currently not lower than they have been in the previous 15 years, especially for developed markets. Thus, the widening of the value spread over the last three years cannot be traced back to a deterioration in growth expectations for value stocks.
The recent value recovery has led to a change in sentiment regarding value stocks. Price momentum – measured as a stock’s return over the last 6 to 12 months – is one way to gauge market sentiment. While value and momentum tend to be negatively correlated – therefore providing diversification benefits – there have been a few periods in history when value stocks exhibited strong momentum. We expect this to happen again in the coming months.
Figure 3 depicts the difference between the median six-month performance of value and growth stocks. The difference has shifted from very negative to positive over the few last months. Since most momentum strategies use price momentum measures over 6 to 12 months and the value turnaround only started about six months ago, they have yet to purchase value stocks significantly. But one should expect them to start buying value stocks in a larger scale now that the market regime shift is clearly reflected in price momentum metrics.
Another way of measuring sentiment is to look at analyst earnings estimate revisions. Analysts tend to issue more upward than downward earnings revisions for expensive stocks than for cheap ones. However, over the last few months, analyst earnings per share (EPS) revisions for value stocks have been as optimistic as they have ever been in recent history. Although we still have to see if analyst earnings expectations will play out as forecasted, current sentiment is in favor of value.
All in all, after a long and harsh quant winter, spring has sprung and value seems ready for summer.
Current sentiment is in favor of value
1The enhanced value strategy is based on a composite of book-to-market (R&D adjusted), EBITDA/EV, CF/P, and NPY. Value stocks are sorted into quintile portfolios based on the valuation composite and in a region and sector respectively country neutral manner for developed and emerging markets. Quintile portfolios are equal-weighted and reformed monthly. The details of the enhanced value strategy are described in Blitz, D., and Hanauer, M., January 2021, “Resurrecting the Value Premium”, Journal of Portfolio Management.

3GP/A is gross profit to assets.
4The difference would be negative for a value strategy solely based on book-to-market. The difference is less pronounced or non-existent for the enhanced value strategy as it is based on a composite of value metrics that use profit measures such as EBITDA and cash flow in the numerator.
