In open-market terms, that means 1 purchase worth €49k on one side and 22 sales worth €3.3M on the other. The net balance comes to €3.3M on the selling side. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Besides market trades, the filings include 1 share grant and 6 option exercises.

On 6 March 2026 came the latest disclosure, an option exercise in Natural Grocers by Vitamin Cottage, Inc. The clock since the last published purchase (30 July 2012) now reads 5,199 days. Typically, a trade is published a median of 2 days after it takes place. Section 16 rules allow two business days to file each Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
