Filings by Dennis J. Keller span 3 companies, the busiest being Covista Inc., Nicor Inc and Ryerson Tull Inc /DE/. Between 6 March 2006 and 9 December 2011, the trades on record add up to 1,228 filings.

Both buying and selling appear: 1 purchase worth €21k, against 1,170 sales worth €45.8M. The amount is not disclosed for 1 filing. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Besides market trades, the filings include 2 share grants and 11 option exercises.

The latest filing, published on 13 December 2011, reports a transaction in Nicor Inc. The last insider purchase was made public on 7 March 2006, 7,536 days ago. Filings reach the SEC (Form 4) feed a median of 1 day after the trade. US insiders must file a Form 4 within two business days of a trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
