Jeffrey M. Leiden: trading record in brief
Jeffrey M. Leiden (chief executive) discloses dealings in 3 companies, chiefly Vertex Pharmaceuticals INC / MA, Quest Diagnostics Inc and Abbott Laboratories. In total, 320 filings cover trades dated from 31 January 2006 to 24 February 2026.
Market trades split into 2 purchases (€76k) and 194 sales (€484.1M). Netting one side against the other leaves €484.0M 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 66 share grants and 55 option exercises.
The latest filing, published on 26 February 2026, reports a share grant of €1.5M in Vertex Pharmaceuticals INC / MA. The clock since the last published purchase (5 May 2010) now reads 6,016 days. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
