Context

• Sales executed under a 10b5‑1 plan are pre-planned trades that allow insiders to sell shares according to a preset schedule and are common for tax planning or diversification; they do not necessarily indicate new insider sentiment.
• For retail investors: purchases are generally more informative about insider confidence; reported sales (especially under 10b5‑1 plans) are routine and should be weighed alongside other company news and fundamentals.
