John Borkholder

John Borkholder discloses dealings in Maxygen Inc to SEC (Form 4). We count 6 filings; the first trade dates from 22 June 2012 and the latest from 13 August 2013.

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.

The latest filing, published on 13 August 2013, reports a share grant of €9,796 in Maxygen Inc. Typically, a trade is published a median of 3 days after it takes place. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
