Context

• A 10b5‑1 plan allows insiders to sell according to a pre‑arranged schedule and is commonly used to avoid trading based on material nonpublic information; it makes these transactions more likely to be routine rather than opportunistic.
• For retail investors, purchases by insiders tend to be more informative signals than sales; factual reporting of sales should be noted but not over‑interpreted without additional context.
