Understanding Signal Strength
Not all insider trading activity is created equal. Learn to evaluate signal strength:
Strong Signals
Multiple insiders, large amounts, good timing
Moderate Signals
Single insider, moderate amounts, mixed timing
Weak Signals
Routine transactions, small amounts, poor timing
Bullish Signals to Watch For
🚀 Multiple Insider Purchases
Signal Strength: Very High
When several executives buy stock around the same time, it's one of the strongest bullish indicators:
- Multiple insiders usually means consensus optimism

- Strong conviction about company prospects
💰 Large Open Market Purchases
Signal Strength: High
When insiders use their own money to buy significant amounts:
- Look for purchases >$100K or >10% of current holdings
- CEO and founder purchases carry extra weight
- Open market (Code P) beats grants/awards (Code A)
📉 Buying on Weakness
Signal Strength: High
Insider purchases after stock declines often signal value buying:
- Purchases within 1-2 weeks of 52-week lows
- Buying after earnings disappointments
- Accumulation during market downturns

Signal Strength: Moderate to High
Regular purchase patterns over several months:
- Dollar-cost averaging by insiders
- Increasing ownership percentages
- Long-term conviction signals
