Leonard Osser: trading record in brief
Leonard Osser (senior executive) discloses dealings in 2 companies, chiefly Milestone Scientific Inc. and Nexalin Technology, Inc. The record holds 31 filings, for trades running from 21 June 2021 to 29 September 2025.
No open-market purchase appears, only 22 sales worth €380k. Besides market trades, the filings include 7 share grants and 2 option exercises.
The newest entry dates from 30 September 2025: a share grant, in Nexalin Technology, Inc. Typically, a trade is published a median of 1 day after it takes place. For comparison, the SEC allows two business days to file a Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
