Insider Trading Guide
SEC Form 4 Overview
The SEC requires corporate officers, directors, and 10%+ shareholders to file Form 4 within two business days of any stock transaction. This public data helps investors gauge insider sentiment and conviction.
Cluster Buying
When multiple insiders buy shares around the same time, it's a particularly strong bullish signal. The involvement of key executives like CEOs and CFOs adds even more credibility to the signal.
Large Purchase Signal
Purchases exceeding $100K are considered 'meaningful buys.' Transactions over $1M suggest strong insider conviction about the company's future. Large purchases near stock lows are especially noteworthy.
Understanding Insider Selling
Insider selling isn't necessarily bearish. Common reasons include stock option exercises, tax obligations, portfolio diversification, and personal financial needs. Buying signals are generally more significant than selling.
