Context A Rule 10b5-1 plan lets insiders pre-schedule trades and is commonly used to avoid trading on material nonpublic information. Sales under such plans are often routine and, by themselves, do not necessarily indicate a change in the insider’s view of the company. For retail investors, purchases generally carry more weight as a bullish signal than routine plan-based sales.
