The 2026-end S&P 500 forecast is underpinned by earnings growing at a healthy 13.2% pace to
$308.80/share. At the same time, the target assumes that the already elevated price to earnings
multiple expands further to 25.7x from 2025’s forecasted P/E of 24.6x. The latter already sits at
approximately the 80th percentile of its historical range going back to the year 1990, while an
implied multiple of 25.7x would sit in the mid-80s percentile, a task that is not necessarily
impossible, but is at the very least somewhat ambitious, requiring a supportive macroeconomic
and interest rate environment that leaves limited margin for error should earnings disappoint.
To illustrate this sensitivity, we stress test potential return outcomes by holding EPS growth
expectations constant under varying P/E regimes. The analysis finds that even modest multiple
compression would be enough to materially reduce the implied expected return, while further
multiple compression would fully offset earnings growth and result in negative price returns.
