David E. Farnsworth: trading record in brief
This profile gathers the share dealings of David E. Farnsworth in Mercury Systems Inc. Between 17 August 2023 and 20 August 2026, the trades on record add up to 15 filings.
Market trades split into 1 purchase (€93k) and 7 sales (€3.0M). On balance, insiders were net sellers of €2.9M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Besides market trades, the filings include 6 share grants. Since January 2026: no purchases and 5 sales on the market.
The newest entry dates from 15 September 2026: a share grant, in Mercury Systems Inc. The clock since the last published purchase (12 February 2024) now reads 979 days. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. Section 16 rules allow two business days to file each Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
