Context
Sales under Rule 10b5-1 plans are pre-scheduled trading arrangements and are commonly used by insiders to sell shares without regard to short-term company developments; they do not, by themselves, indicate a change in the insider’s view of the company. For retail investors, purchases typically carry more direct bullish signaling than routine, pre-planned sales.
