Signal history

Eileen Serra: trading record in brief

Eileen Serra, listed as board member, has filed trades across 3 companies (mainly through SEC (Form 4)), most often in Capital ONE Financial Corp, Gartner Inc and Boxed, Inc. Over a trading history stretching from 6 May 2021 to 8 June 2026, the count stands at 12 filings.

The open-market side counts 1 purchase for €167k alongside 1 sale for €561k. Sales outweigh purchases by €394k. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The rest of the record consists of 7 share grants and 3 option exercises.

The record was last updated on 10 June 2026 with an option exercise in Gartner Inc. The clock since the last published purchase (10 May 2022) now reads 1,622 days. The median gap between a trade and its publication by SEC (Form 4) is 4 days. The legal deadline for a Form 4 is two business days after the transaction. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
