Market valuations aren't mean reverting

Stock market valuations can make investors nervous when elevated above long-term averages.

And valuations are very much elevated right now.

“The forward 12-month [price/earnings] ratio for the S&P 500 is 21.7,” Factset’s John Butters observed on Friday. “This P/E ratio is above the 5-year average (17.4) and above the 10-year average (15.6).”

As we’ve written quite a bit, rich valuations alone are no reason to avoid or dump stocks. And they’ve historically revealed almost nothing about what stocks do in the next 12 months.

And as Myles Udland noted last week, valuations often spend extended periods of time far above average while spending very little time trading near their averages. (See more here, here and here.) Indeed, much of the gains you see in the stock market have been achieved while valuations appeared expensive.

It might be unsettling, but the counterintuitive truth is valuations don’t arbitrarily gravitate back to historical averages.

“The long cycles we see in the P/E ratio are driven by economic factors,” Wells Fargo analysts said in a 2016 note. “The S&P 500 P/E ratio is not stationary and not mean reverting...”

In recent years, everyone from billionaire investor Warren Buffett to Fed Chair Jerome Powell have stressed the importance of rates when considering valuations. And with rates having been at unusually low levels for years by historical standards, you could argue we’ve been in a new market regime that justifies elevated P/E ratios.

Valuation considerations for 2021

It’s with all this context that we read Wall Street’s 2021 stock market forecasts, which include a lot of strategists making the case for higher prices even as valuations remain elevated.

"Yes, valuations appear stretched at first glance, but they also need to be considered within the context of historically low interest rates and little inflation, ingredients that are likely to persist throughout 2021 and beyond, in our view,” BMO Capital’s Brian Belski wrote on Thursday. “When viewed through this lens, we believe it is not unreasonable for market valuation to sustain (or even expand slightly) from its current level."

Belski sees the S&P 500 climbing to 4,200 next year.

On the other hand, Morgan Stanley’s Mike Wilson is a bit more cautious, forecasting the S&P to top out at 3,900.

"With respect to multiples, we expect rates moving higher will be a headwind to valuations, though falling equity risk premium in a recovering economy will provide some offset,” Wilson said. "The market has entered the phase of the economic recovery when multiples compress as earnings move higher.”
