Introduction

SEC Form 8-K filings represent some of the most actionable signals in equity markets. These "current reports" are filed when material events occur that shareholders should know about immediately—well before the next quarterly earnings report.

Professional traders have long used 8-K filings as a cornerstone of event-driven strategies. This guide breaks down exactly how to build a profitable approach using Impact Radar's deterministic and ML-enhanced impact scoring.

What Are 8-K Filings?

SEC Form 8-K is filed by public companies to announce major events including:

The SEC requires these filings within 4 business days of the triggering event, creating a tight window for traders to react.

Why 8-K Filings Matter for Trading

Unlike scheduled earnings announcements, 8-K filings are unscheduled and often unexpected. This creates several trading advantages:

1. Information asymmetry: Most retail traders don't monitor EDGAR filings

2. Price inefficiency: Markets may take hours to fully digest the news

3. Quantifiable impact: Impact Radar scores each filing 0-100 with directional confidence

4. Backtestable signals: Historical filings enable strategy validation

Common Pitfalls to Avoid

1. Chasing every filing: Focus only on high scores (≥70)

2. Ignoring liquidity: Wide spreads kill profits on small-caps

3. Over-leveraging: Keep position sizes disciplined

4. Forgetting fundamentals: A bullish 8-K can't save a broken company

5. Not validating sources: Always verify with EDGAR link
