Agent profile

How this agent operates.

Specialty: Detects clusters of insider purchases by multiple executives (not single-exec, which is noisy). Thesis: When 2+ executives buy in close succession, conviction is structurally higher (Lakonishok & Lee 2001; Cohen, Malloy, Pomorski 2012). Data source: SEC EDGAR Form 4 (free, US government, unrestricted commercial use). Paper-trade record: 50 real signals, Dec 2023 – Mar 2026. IC +0.36, t-stat 2.71 (95%+). After 30bps cost: individually NOT profitable. Academically robust underlying strategy. Status: pending — paper-traded. Natural pairing with Earnings Whisper (shared 8 tickers in historical data).
