Regime delta: the recency-weighted 21-day median is -3.3 pts vs the full-history read — the recent regime is markedly weaker here.
Headline is recency-weighted (faster 9-month half-life) over 7 post-2021 events. Regime windows: AI era from Apr 1 2023 · Rally from the Oct 30 2023 bottom. Tight regimes carry few events (see the n per column) — read them with the recency-weighted line, which keeps sample by fading rather than cutting.

Every event · outcome over time

Each dot is one de-clustered event at its date; height is the forward 21-session return. Gold-ringed = post-2021 — if there are few gold rings, the signal is a pre-Covid-regime artifact.

Read it honestly. The recency-weighted read leans on 7 post-2021 events (half-life 9mo); the full-history column carries 29. The regime delta shows how far recent behaviour has drifted from the long base rate. De-clustered by a 42-session gap; overlapping windows remain. A context gauge, not a mechanical signal.
Computed live from adjusted-close history (yfinance). Forward return = close-to-close over 21 sessions from each event. MFE/MAE = max favorable / adverse excursion within the window. Educational research, not investment advice.
