Context

• Sales under a Rule 10b5‑1 plan are pre-scheduled and often represent routine disposition (e.g., diversification or liquidity needs) rather than an ad hoc signal about company prospects. Retail investors should treat scheduled insider sales with caution and weigh them alongside other information (company fundamentals, other insider activity, and market conditions).
• Purchases typically carry more direct informational value about insider sentiment than planned sales.
