Cross-sectional PEAD leaderboard of recent BEAT/MISS earnings announcers
Ranks RECENT S&P 500 earnings announcers (within window_days) by EPS surprise magnitude, split into a BEAT long side and a MISS short side. Recent announcers are seeded from the market-wide earnings calendar (rows with both an EPS actual and estimate, intersected with the S&P 500 constituent universe), bucketed by the same BEAT/MISS thresholds as the per-ticker PEAD endpoint, then CONFIRMED against each company's SEC 8-K item 2.02 filing (accepted only when a filing date matches the calendar date within +-1 day). Confirmed candidates are measured against a shared market proxy: an immediate reaction CAR over [0, +1] and a realized drift-to-date CAR over [+2, min(elapsed, +20)]. Candidates are ranked by the SURPRISE (the conditioning variable known at announcement time), NOT by realized drift, which is reported as descriptive evidence only. This is a small cross-section of one recent window - descriptive, not a backtest of the PEAD anomaly. Candidates that cannot be confirmed against SEC filings, or that lack sufficient price history, are excluded and counted in diagnostics rather than failing the request.
