Terrance Mcguire

This profile gathers the share dealings of Terrance Mcguire across 9 companies, led by Invivyd, Inc., Alector, Inc. and X4 Pharmaceuticals, Inc. In total, 134 filings cover trades dated from 15 March 2016 to 28 July 2026.

In open-market terms, that means 21 purchases worth €21.9M on one side and 22 sales worth €12.7M on the other. The totals exclude 6 filings filed without an amount. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Other entries cover 34 share grants.

The median purchase comes to €239k. On 7 out of 8 purchases, another insider of the same company was buying within the same 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

The latest filing, published on 30 July 2026, reports a share grant in Seer, Inc. The last purchase on record was published on 12 August 2021, which is 1,898 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction. 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.
