This is a good time to check in with valuation ratios. These have been challenging times for value stocks. Over the 10-year period ending March 31, 2020, the Fama/French US Value Research Index returned an annualized 5.06%, well behind the 13.04% achieved by the Fama/French US Growth Research Index. This performance divergence has resulted in a substantial widening of the price-to-book spread between value and growth stocks in the US, as shown in Exhibit 1.
Extending this analysis to different markets and asset classes reveals further evidence of widening valuation spreads between value and growth. As we see in Exhibit 2, spreads among large cap stocks in the US, non-US developed, and emerging markets have all generally expanded over the past decade. This was also true for small cap stocks in the US and non-US developed markets, with only emerging markets small caps bucking the spread-widening trend.
What do we make of the valuation ratio data? A stock’s price represents the value of a company’s expected future cash flows discounted back to the present. So low valuations can result from low expectations of future cash flows, high discount rates, or a mix of the two. It’s not possible to cleanly isolate cash flow and discount rate effects from the data. But to the extent that low valuations reflect high discount rates, expected returns will be higher going forward.
To the extent that widening spreads between value and growth are attributable to increases in the discount rates for value relative to growth, the implication would be a higher expected value premium. However, research from Dai (2016) (1) suggests investors should be cautious using valuation spreads as inputs for asset allocation decisions. While regression analysis provides some evidence of a link between valuation spreads and subsequent value premiums, hypothetical timing strategies that switch between value stocks and growth stocks based on the spread in their valuations fail to consistently outperform a simple buy-and-hold value strategy.
What’s the takeaway for investors? Even if the spreads in valuations between value and growth vary through time, the important part is that there is a spread. Investors demand different expected returns across stocks, and that shows up in part through different valuations. It’s reasonable to expect that securities with lower prices relative to fundamentals should have higher expected returns. While value premiums may not show up every day, year, or decade, we believe maintaining consistent exposure to value stocks is the most robust approach for capturing the value premium, regardless of current valuations.
