Every open-market trade on record is a purchase: 5 purchases worth €1.5M, and no sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price. So far in 2026, the count stands at 2 purchases and no sales.
The median purchase comes to €137k. Of 5 purchases, 1 formed part of a group of insiders buying within 30 days of each other. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. Ninety days after publication, 3 purchases show a median change of -24.9%, with the price up in 33% of them. These figures describe past trades and do not predict future prices.
The latest filing, published on 8 September 2026, reports an open-market purchase of €57k in NEUROONE MEDICAL TECHNOLOGIES Corp. Typically, a trade is published a median of 3 days after it takes place. Section 16 rules allow two business days to file each Form 4. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
