Predict Stock Returns Without ML Models
Rule-based pattern discovery from SEC filing events
Mined from 4.8M SEC filing events • Validated 2020-2025
Signal: Management action (CEO/CFO appointment, refinancing, buyback, restructuring) during stock distress
Signal: Red flag (restatement, investigation, material weakness) followed by swift management action <30 days
Signal: 3+ negative events in 60 days = potential market overreaction
Signal: 10+ material events in 30 days = corporate transformation/inflection point
Real returns from pattern-detected opportunities
Red Flag Recovery Pattern
Pattern Recognition: Red flag event followed by comprehensive management action. Despite slower response, the combination of reorganization and refinancing signaled strong turnaround potential. 6-month return of +47,633% validates the pattern.
Sentiment Divergence Pattern
Pattern Recognition: Extreme clustering of negative events created oversold opportunity. When bad news is operational (not existential) and company survives, recovery can be explosive. This validates the sentiment divergence pattern.
Event Clustering Pattern
Pattern Recognition: 227 events in one month signals massive transformation. This level of activity (10x normal) typically precedes major corporate changes like M&A, restructuring, or business pivots. Strong indicator for micro-cap stocks.
Contrarian Rebound Pattern
Pattern Recognition: Stock down 81% but management takes decisive action (CEO appointment + refinancing). The combination of leadership change and financial restructuring signaled turnaround. 9-month return of +94% proves the contrarian rebound pattern.
Current opportunities detected by pattern matching
Why Strong: Multiple recovery actions after red flag. New financial leadership + restructuring signals turnaround commitment.
Why Strong: 138 events signals major transformation underway. Large-cap with this level of activity indicates significant strategic initiatives.
Why Interesting: Rare refinancing activity (IDF 10.92) indicates significant financial restructuring. REIT sector improvement play.
Why Interesting: High pharma activity (78 events) with positive lean suggests pipeline/regulatory progress. Typical of major clinical milestones.

Extract all high-value events 30 days before each SEC filing. Create event signature (count, types, sentiment, IDF scores).
Measure stock performance 1, 3, 6, and 9 months after each filing. Classify into performance buckets (high, medium, low, negative).
Group filings by performance bucket. Find common event patterns within each bucket using association rule mining.
Create IF-THEN prediction rules: "IF pattern X (e.g., CEO + refinancing) THEN expect bucket Y (e.g., +125% return) with Z% confidence"
For new filings: Extract event signature → Match to discovered patterns → Predict performance without ML models!
