Glamour stocks, or “hot stocks” as they’re sometimes called, are shares that investors believe will increase in value faster than the rest of the market. They exhibit a tendency to create their own momentum or “lift”, as investors chase recent outperformance and fear missing out, which leads the price ever higher. The danger is that prices move so far away from fundamental values that they eventually fall sharply, which results in value stocks outperforming. The evidence suggests that’s precisely what has happened over the last year or so. And, as LARRY SWEDROE explains, value stocks still look very cheap, relative to historic levels. So are we seeing a regime shift, away from glamour stocks, towards value stocks?
As the authors of the study Clairvoyant Value and the Value Effect demonstrated, even though growth stocks have historically produced faster growth in earnings than value stocks, a systematic value strategy relying on perfect foresight of future earnings, cash flows or book values would have paid handsomely over the long term. In other words, great (faster growing) companies don’t necessarily make the greatest investments.
In addition, systematic value strategies that rely on a diversified set of simple valuation metrics such as price-to-book, price-to-earnings or price-to-cash flow based on current prices and earnings, cash flows and book values have performed as well as those that replace current earnings, cash flows and book values by the analysts’ forecasts of those metrics.
However, the years 2017 through 2020 were a “dark winter” for value investors as value stocks endured a period of severe underperformance that resulted in their largest historical drawdown. This period tested the patience and discipline of value investors and caused many to question the future of the value premium, asking: Is this time different? Has there been a regime change?
Despite the existence of the value premium over the long term, there have been other periods when value underperformed, with the late 1990s setting the previous record for a value drawdown. Value drawdowns can happen either for fundamental reasons or if investors become overoptimistic about the expected growth rates of glamour stocks and/or too bearish about growth rates for value stocks. Either way, the result is a widening of the gap in their valuations. Investor sentiment and herd behaviour can extend the expansion of value spreads for periods longer than many investors have the patience for.
The source of the dark winter for value stocks
Benoit Bellone and Raul Leote de Carvalho, authors of the study Value versus Glamour Stocks: The Return of Irrational Exuberance?, published in the February 2022 issue of The Journal of Investing, examined the evidence to try to identify the source of value’s underperformance during the 2017-2020 drawdown. To understand the drivers of such poor recent performance, they considered a decomposition of the value premium into a sum of three different terms: 1) the change in value spreads, 2) the difference in growth of fundamental measures between value and expensive stocks, and 3) the difference in dividend yields between value and expensive stocks.
The authors explained: “The first term is positive when value spreads compress, resulting from prices converging toward fundamentals. The second term tends to detract from performance, because value stocks tend to have lower growth rates than their expensive peers, even after neutralising sectors. The third term tends to be positive, because value stocks tend to pay higher dividends than expensive stocks.”
Bellone and de Cavalho also investigated the returns of other factor styles conditional to changes in the valuation spreads of value stocks relative to glamour stocks. To investigate how prices of stocks behaved relative to their fundamental values, they created a composite measure of value spreads calculated from a diversified selection of common value factors: book equity-to-price, tangible book equity-to-price, free cash flow yield (excluding financials), EBITDA-to-enterprise value (excluding financials) and forward earnings-to-price. Their data sample covered the period July 31, 1995-April 30, 2021. Following is a summary of their findings:
- There were three major periods of value spread expansions (1998-2000, 2007-2009 and 2018-2020) and two periods of more modest increases (2011-2012 and 2015).
- Over the period 2018-2020, value spreads recorded a three-standard-deviation expansion shock comparable only to the tech bubble of the late 1990s. While value spreads may have peaked at the end of 2020, they had not yet compressed much. The picture was similar in the United States and Europe.
- The spreads between valuations of value stocks and growth stocks expanded in all regions and sectors (with the exception of the energy sector) during the period of underperformance, reaching extreme levels similar to the peaks reached during the tech bubble in 2000.
- As was the case during the tech bubble, the most recent drawdown in performance of value strategies is mainly attributed to glamour stocks getting more expensive, not value stocks getting cheaper.
- The performance of value stocks has been significantly better in periods of value spread compression and weaker in periods of value spread expansion. The same is true for small-capitalisation stocks but is even more pronounced.
- Sector neutral and beta neutral value strategies produced superior performance.
- The performance of other robust factor styles — in particular, quality and low volatility — is not sensitive to changes in value spreads.
- Picking the best single raw factor with a perfect foresight timing strategy based on the value spread would have barely outperformed a diversified multifactor composite raw aggregation of factor styles relying on an equal risk-contribution weighting scheme, gross of transaction costs.
- Since 2003 changes in value spreads have been highly correlated with changes in differences between analysts’ earnings growth forecasts for value and growth stocks. There have been three episodes with a major widening of the expected earnings growth differences, which seem to relate to the economic recessions of 2001-2002, 2007-2008 and 2020. Changes in growth differences peaked in June 2020 and have been slowing since. In addition, each episode of expansion of growth forecast differences was followed by periods of compression in the valuation spread.
- The increased spread in valuations, not changes in realised earnings, explained the underperformance.

NOTES: MSCI World, MSCI USA, and MSCI Europe index universes. Prior to 2000, the MSCI index universes were based on a proxy constructed from the largest-cap stocks worldwide (July 31, 1995–April 30, 2021).

Their findings led Bellone and de Cavalho to conclude: “Value spread changes have detracted from the value premium since 2018 and are the likely key explanation of the underperformance of value stocks in every region and macro sector. Prices moved away from fundamental values, and value spreads reached extreme levels everywhere by the end of 2020.”
Investor takeaways
While prior research has found that valuation spreads for value stocks relative to their expensive peers tend to be correlated with the future value premium (for historically large value spreads, a larger value premium is more likely in the five years that follow), the use of value spreads as a tool to time the value premium is limited because it is impossible to know when value spreads will mean revert. Thus, forecasting the value premium over short horizons can go very wrong if value spreads continue to expand in the shorter term — markets can remain irrational longer than many investors can stay disciplined.
The fact that value spreads and earnings growth forecast differences peaked in 2020 and that value spread compression periods have been characterised by strong outperformance of value stocks relative to expensive peers is good news for investors, as both value spreads and differences in earnings growth forecasts still have a long way to go if they are to fall back to historical averages. According to AQR’s research, as of year-end 2021, their measure of valuation spreads for global value stocks were still at the 99th percentile of cheapness for the period beginning in 1994. In addition, and perhaps more importantly, they noted that “current value spreads imply that expensive companies will outgrow cheap companies by ~120% over the next 5-years,” which is “a rate that is 2-3x higher than ever realised in the past.” AQR also noted that if value stocks were to repeat their outperformance over the period 2000-03, they would outperform by 108 percentage points.
The bottom line is that while growth stocks in particular, and market indices in general, are quite expensive relative to historic levels, relative to growth stocks, value stocks are very cheap.
