Market Mechanics and Regulatory Framework
Tracking aggressive insider buying after earnings selloff episodes is one of the most reliable contrarian playbooks in equity market trading. When a company experiences a 15% to 30% gap down following an earnings release due to temporary supply chain disruptions or conservative forward guidance, emotional selling often overshoots fair intrinsic value. If the CEO and CFO step into the open market within days of the post-earnings trading window opening to purchase millions of dollars in personal stock, it invalidates the market panic narrative and establishes a firm fundamental price floor.
| Selloff Severity | Insider Response Window | Historical 6-Mo Mean Reversion | Risk / Reward Ratio |
|---|---|---|---|
| 10% - 15% Post-Earnings Drop | Trades placed within 48-72 hours | +14.2% average return | 1 : 2.8 upside skew |
| 15% - 25% Guidance Disappointment | CEO + CFO cluster purchases | +22.8% average return | 1 : 3.6 upside skew |
| >25% Panic Capitulation | Multiple directors + C-suite buys | +31.5% average return | 1 : 4.4 upside skew |
