Low rates and overly bullish expectations have driven the S&P 500 to record highs. But now rates are rising, and that means multiples will need to contract. Just how much those multiples need to fall is the concern, and it could be a lot.  

The S&P 500 trades at around 18 times 2023 earnings estimates of $219.90 per share, according to data from Refinitiv. That is well above the historical average of 14.9 since 2014 and indicates that future earnings growth expectations are very high. Should the PE return to that average over time, it would value the index at 3,256, 16% lower than its value of 3,915 on Mar. 18.
