John F. Glick

John F. Glick, listed as board member, has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Lufkin Industries Inc and Tetra Technologies Inc. Between 23 April 2007 and 21 May 2025, the trades on record add up to 205 filings.

In open-market terms, that means 27 purchases worth €377k on one side and 136 sales worth €8.9M on the other. Taken together, the sales exceed the purchases by €8.5M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Outside the open market, there are 10 share grants and 31 option exercises.

The median purchase comes to €5,721.

On 22 May 2025 came the latest disclosure, an option exercise in Tetra Technologies Inc. The latest purchase dates back some time: it was published 2,314 days ago, on 23 June 2020. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. US insiders must file a Form 4 within two business days of a trade. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
