The assistant answers from what CWST has actually filed: 16 annual reports filed with the SEC, 59 Form 4 filings from the last year and 3 funds that hold it. Every figure in a reply links to the filing it came from, so an answer can be checked rather than believed.
Pressing one answers it here, from CWST's filings and figures. One a day without an account; a free account has its own, and no card.
See every Form 4 CWST insiders have filed, not the latest few.
Ten seconds, no card, and nothing to cancel.

From SEC Form 4 filings, filed by officers, directors and 10%-owners within two business days of a transaction. “Indirect” holdings (a trust, an LLC, a family member) are included and not distinguished from direct ones in this table.
Past transactions say nothing about future ones, and none of this is investment advice.
See who bought, not who was handed shares
