Peter M. Hecht: trading record in brief
Peter M. Hecht is a declared insider at 2 companies (chief executive); the most frequent names are Ironwood Pharmaceuticals Inc and Korsana Biosciences, Inc. We count 85 filings; the first trade dates from 2 August 2010 and the latest from 16 July 2026.
Market trades split into 5 purchases (€4.7M) and 18 sales (€9.2M). Taken together, the sales exceed the purchases by €4.5M. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Other entries cover 10 share grants and 29 option exercises.
Half of the purchases are above €608k and half below. 1 out of 4 purchases came within 30 days of a purchase by at least one other insider of the same company. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. After 3 purchases with a full 90-day history, the hit rate stands at 67% and the median 90-day move at +16.0%. This is a record of the past, not a forecast.
The record was last updated on 20 July 2026 with a transaction in Korsana Biosciences, Inc. The most recent open-market purchase was published on 7 June 2021, 1,981 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. The legal deadline for a Form 4 is two business days after the transaction. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
