Context
A 10b5‑1 trading plan is a pre-arranged program that allows insiders to sell shares at set times or amounts; transactions under such plans are typically considered routine and pre-specified rather than ad hoc expressions of sentiment. Sales reduce insider stock holdings but, by themselves, do not necessarily indicate a change in the CEO’s view of the company.
