How to Interpret Insider Trading Data
Insider trading data from SEC Form 4 filings can provide valuable signals, but requires context:
- Open market purchases are most significant: When insiders voluntarily buy shares with their own money, it often signals confidence.
- Buying the Dip matters: Insiders purchasing when their stock is down significantly may have insight into the company's prospects.
- Selling is less informative: Insiders sell for many personal reasons unrelated to company outlook.
- Cluster buying is powerful: Multiple insiders buying around the same time is a stronger signal than individual trades.
- Consider position size: Large purchases relative to an insider's holdings show higher conviction.
