David Edward Johnson: trading record in brief
Filings by David Edward Johnson span 3 companies, the busiest being Exelixis, Inc., AMAG Pharmaceuticals Inc. and Liquidia Corp. In total, 14 filings cover trades dated from 8 October 2019 to 16 June 2026.
Both buying and selling appear: 5 purchases worth €15.1M, against 1 sale worth €2.4M. Netting one side against the other leaves €12.7M of net buying. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Other entries cover 6 share grants.
Half of the purchases are above €3.6M and half below. The 4 purchases reviewed show no overlap with other insiders buying the same stock within a month. Looking at 3 purchases old enough to measure, the stock rose over the following 90 days in 67% of cases; the median change was +1.3%. These figures describe past trades and do not predict future prices.
The newest entry dates from 18 June 2026: a share grant, in Liquidia Corp. The last insider purchase was made public on 26 November 2025, 347 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. 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.
