Douglas Michael Polinsky

Douglas Michael Polinsky has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Mill City Ventures III, Ltd and Liberated Syndication Inc. In total, 11 filings cover trades dated from 31 December 2021 to 12 March 2025.

No open-market sale appears; the market trades are 6 purchases worth €33k. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Besides market trades, the filings include 5 share grants. So far in 2025, the count stands at 1 purchase and no sales.

Half of the purchases are above €3,069 and half below. 2 out of 5 purchases came within 30 days of a purchase by at least one other insider of the same company. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

Most recently, on 14 March 2025, the filings show an open-market purchase worth €18k in Mill City Ventures III, Ltd. Typically, a trade is published a median of 2 days after it takes place. US insiders must file a Form 4 within two business days of a trade. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
