Summary
In the March 2026 episode of Charts and Perspective, TMX Vetify analyst Jennifer Nash examines whether the U.S. equity market remains overvalued, using four long‑standing valuation gauges compared against more than a century of data.
The Crescent PE ratio, which ties earnings to GDP, sits at 40.2, a level that historically precedes major market corrections. The Shiller PE10 is 37.1, already above the 1929 peak, indicating investors are paying a hefty premium for ten‑year inflation‑adjusted earnings. The Q ratio stands at 1.91, meaning the market’s price is nearly twice the cost to rebuild its assets, while the S&P’s regression‑to‑trend metric shows the index 184 % above its long‑run growth line.
Nash notes that normalizing the four metrics yields an overvaluation range of 108 % to 184 %, and a geometric mean of 162 %—more than three standard deviations from historical norms for eleven consecutive months. She cautions that such extreme readings have rarely persisted, yet overvaluation can endure for years, as seen in the past decade.
For investors, the data signals heightened risk of a sizable correction, though timing remains uncertain. The modest decline in valuations since December offers a glimpse of mean‑reversion, suggesting portfolio managers should temper return expectations and prioritize long‑term horizon planning.
