Shiller CAPE

Price against the ten-year average of real earnings (Shiller's cyclically adjusted P/E) — earnings power.

40.6
p99 +1.6σ vs trend
In its expensive level since Dec 2023 — the 21st expensive period since 1881.
+1.58σ
pale red AS OF 2026-10
CAPE vs its expanding log-trend · the VR-DR-4-C fit, stored nightly · rung boundaries ±1σ / ±2σ.

p99 says expensive vs all history; +1.58σ says how stretched vs where the trend expected it today — two questions, two answers. October's reading, like the months before it, can still move: multpl restates recent months as companies report their earnings, for months after they end, and the site takes each restatement the night it appears.

Log scale. Hover shows the month’s as-of percentile. A period moves only if the values under it do — for CAPE, only in its recent months, as multpl restates them.

Expensive periods — the register

Periods of at least two consecutive months at or above the 95th percentile of this measure's own history up to that month; a single month below ends a period.
