Equity Valuation (CAPE / ECY / Earnings-vs-Multiple)

Valuation numbers without historical context are noise. This operator computes the Shiller anatomy — CAPE, Excess CAPE Yield, and the exact split of every price move into its earnings leg and multiple leg — over the full 154-year record, and reports percentiles against that record. Its defining feature is the honesty contract: readings run through the dataset's last earnings month (as_of), staleness is surfaced in a banner, and nothing is extrapolated.
