Louis J. Lavigne Jr.: trading record in brief
Louis J. Lavigne Jr. is a declared insider at 2 companies (board member); the most frequent names are Zynga Inc and Alector, Inc. In total, 11 filings cover trades dated from 17 May 2021 to 17 June 2026.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.
The latest filing, published on 17 June 2026, reports a share grant in Alector, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay 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.
