Rates and Stocks: How Low Can Valuations Go?

Equity valuations have fallen substantially as central banks hike interest rates to combat inflation. History suggests that unless rates rise dramatically from here, valuation compression may have nearly run its course in the US stock market.

Rising interest rates have dominated this year’s macroeconomic and market agenda. The 10-year US Treasury yield jumped from 1.51% to 4.05%, from the beginning of 2022 through the end of October. Over the same period, the forward price/earnings ratio of S&P 500 stocks fell from 22.3x to 16.7x—a 25% decline. Rising rates push up the discount rate used to value stocks, which tends to push valuations down. Growth stocks with cash flows that are further out in the future often get disproportionally hurt by rising rates—a trend that has played out this year.

Searching for the Bottom

Are we nearing an end to valuation compression? It’s still hard to say, because a company’s P/E ratio is determined by both its share price and earnings per share. In many cases, earnings forecasts haven’t come down enough to reflect the potential business decay ahead. Given uncertainties about inflation, rates and growth, some investors are concerned that share price declines and current valuations don’t yet reflect the deteriorating environment.
