Context
A 10b5-1 trading plan lets insiders sell shares according to a pre-set schedule and is commonly used to avoid accusations of opportunistic trading. Such planned sales do not necessarily reflect a change in the insider’s view of the company. For retail investors, purchases typically carry more informational weight than routine, pre-planned sales.
