Context
Sales executed under a 10b5-1 plan are pre-arranged and often routine; they do not necessarily indicate a change in the insider’s view of the company. For retail investors, purchases typically carry more weight as signals than routine sales, but the existence of a 10b5-1 plan is an important disclosure to note.
