Mark Cook

Mark Cook has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Red HAT Inc and Channeladvisor Corp. In total, 88 filings cover trades dated from 17 December 2007 to 6 March 2019.

In open-market terms, that means 6 purchases worth €417k on one side and 22 sales worth €2.7M on the other. Netting one side against the other leaves €2.2M of net selling. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Outside the open market, there are 36 share grants and 24 option exercises.

Half of the purchases are above €80k and half below. Clusters matter here: 1 out of 5 purchases overlapped with buying by a colleague within 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

The latest filing, published on 7 March 2019, reports a share grant of €32k in Channeladvisor Corp. The most recent open-market purchase was published on 20 February 2018, 3,183 days ago. Typically, a trade is published a median of 1 day after it takes place. The legal deadline for a Form 4 is two business days after the transaction. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
