Graham O. Mattison

Graham O. Mattison is a declared insider at 2 companies; the most frequent names are Arq, Inc. and ADA-ES Inc. Over a trading history stretching from 22 February 2013 to 1 March 2016, the count stands at 15 filings.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.

Most recently, on 3 March 2016, the filings show an option exercise in Arq, Inc. The median gap between a trade and its publication by SEC (Form 4) is 4 days. The legal deadline for a Form 4 is two business days after the transaction. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
