The poor performance delivered by value strategies from 2018 to 2020 was accompanied by an extreme widening of valuation multiples between value and growth stocks, with the former getting cheaper than the latter. But the solid recovery over the last two years could perhaps leave some investors wondering whether the value style is now less attractive.

In Figure 1 we show the valuation spread of the value factor,¹ meaning the differences in valuation multiples of value and growth stocks.² As we control for valuation differences that are normally observed between both portfolios, a valuation spread that is above one indicates cheapness, while a reading below one implies that the factor is relatively expensive.

Interestingly, the spread has only shrunk slightly during this period. More specifically, it is still wider as at the end of October 2022 than it was at the beginning of the value winter in 2018. To put things into perspective, the current spread is even wider than it was at the peak of the dot-com bubble in 2000.

Furthermore, value is not only cheap from a relative perspective, but also on an absolute basis as it trades at a forward price-to-earnings ratio (PE) of slightly above 8x. Therefore, the medium-term return expectations for Value are bright, especially if valuations revert to ‘normal’ levels (more on this in the full article).

Despite the strong recent recovery, the value factor is still cheaper than it was at the beginning of its drawdown. This is because, while changes in the value spread explain a large portion of the value returns, they do not explain them entirely. The remaining variation stems from three components: namely carry, portfolio migration and changes in fundamentals (these are discussed in detail in the full article).

A popular question is whether the latest rise in interest rates caused the recent value comeback. In our 2021 article,³ we already investigated this notion and documented that while the relationship has been evident recently, it is much weaker over the long run and for longer-return horizons. In this section, we revisit this issue but approach it in a less technical way.

Figure 2 illustrates the relationship between US value returns and contemporaneous changes in the US 10-year Treasury yield. The chart confirms our previous research results as we find little to no evidence that the value factor correlates to interest rate changes for the period spanning from January 1986 to December 2017. However, the correlation has been higher over the last five years.

But even in recent years, the relationship has been far from perfect. In fact, changes in interest rates explain only a small fraction of the variation in the value returns. Interestingly, the last few months indicate that the relationship may have weakened again. For instance, May 2022 was an excellent month for value while yields slightly decreased, whereas August 2022 was a rather bad month for the factor even though interest rates increased by nearly 50 basis points.

Based on this analysis, we believe that the relationship between value returns and interest rates is not structural – or causal – but more a temporary phenomenon that might well provide some tailwinds for value in the months ahead. However, while the positive relationship between value and yields might persist for some time, possibly due to some self-fulfilling prophecy, we do not believe that interest rates will be the decisive factor for value in the years ahead.

One reason many investors might believe that interest rates drive the returns of the value factor could be based on the argument that growth stocks exhibit longer duration than their value counterparts. Therefore, they should benefit from a lower discount rate being applied to their cashflows and suffer from rising yields.

We acknowledge this line of reasoning but believe that the relationship is ambiguous, meaning one could argue that value stocks are ‘bond-like’ as their prices are driven less by growth expectations and more by their earnings and dividend power in the years ahead. This would imply a negative relationship between value returns and interest rates.

That said, we looked into whether expensive stocks really do have higher future growth. In our analyses, we sort stocks based on valuation multiples and not on past or expected growth. And while companies with high historical growth in sales or earnings typically trade at higher multiples, future long-term growth is much harder to forecast.

Figure 3 depicts the previous five-year realized growth in earnings and analysts’ long-term (five-year) earnings per share (EPS) growth expectations at portfolio formation (t=0), and up to ten years (t=120) after this for the cheap (‘value’) and expensive (‘growth’) quintile portfolios versus the universe. The chart shows that the spread for both historical growth and growth expectations between value and expensive firms is indeed highest at portfolio formation.

Analysts expect expensive companies to generate about 4% higher EPS growth than the average company, while value firms are expected to deliver around 2.5% lower growth. These numbers are remarkably similar to the realized growth numbers that the two groups of stocks achieved over the five years before portfolio formation. Therefore, it seems that analysts extrapolate past growth into the future.

This difference in growth expectations is a key reason why investors are willing to pay a higher price for growth firms. However, these differences are not persistent. As shown in the chart, the spread in both growth expectations and realized growth rapidly converges in the years after portfolio formation, with value stocks experiencing improvements in growth realizations and expectations, whereas their expensive peers encounter deteriorating growth realizations and expectations.

After eight years, we see that the actual difference is less than 1%. Therefore, investors appear to be overpaying for the expected growth differences at portfolio formation, as analysts and other market participants extrapolate historical growth too far into the future. In other words, realized growth does not live up to expectations. As a result, we view these converging growth expectations as one of the driving forces behind the value premium.
