Context
- These sales were executed under a Rule 10b5-1 plan to satisfy tax obligations related to RSUs — a common, routine reason insiders sell shares and not necessarily an indicator of a change in view on the company.
- For retail investors, purchases typically carry more direct insight into insider confidence; routine tax-related sales are less informative about management’s near-term outlook.
