James l. Bierman

James l. Bierman is a declared insider at 4 companies (board member); the most frequent names are Tenet Healthcare Corp, Mimedx Group, Inc. and Novan, Inc. Over a trading history stretching from 20 May 2016 to 27 July 2026, the count stands at 30 filings.

The open-market side counts 3 purchases for €13k alongside 5 sales for €3.9M. Taken together, the sales exceed the purchases by €3.9M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 16 share grants and 5 option exercises. In 2026 alone, the filings show no purchases and 1 sale.

Half of the purchases are above €3,174 and half below. Clusters matter here: 3 out of 3 purchases overlapped with buying by a colleague within 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

On 28 July 2026 came the latest disclosure, an open-market sale for €1.1M in Tenet Healthcare Corp. The last insider purchase was made public on 11 April 2022, 1,654 days ago. Filings reach the SEC (Form 4) feed a median of 4 days after the trade. US insiders must file a Form 4 within two business days of a trade. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
