William L. Marks

William L. Marks discloses dealings in 3 companies, chiefly Adtran Inc, Whitney Holding Corp and Cleco Corp. We count 73 filings; the first trade dates from 27 January 2006 and the latest from 31 December 2018.

Both buying and selling appear: 12 purchases worth €494k, against 7 sales worth €2.0M. Netting one side against the other leaves €1.5M of net selling. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Besides market trades, the filings include 21 share grants and 20 option exercises.

A typical purchase (the median) is worth €24k. For 7 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 14% of cases, with a median move of -20.8%. Past outcomes like these are no guarantee of what comes next.

On 3 January 2019 came the latest disclosure, an option exercise in Adtran Inc. The last insider purchase was made public on 25 July 2012, 5,219 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 days. US insiders must file a Form 4 within two business days of a trade. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
