Michael Larson

Michael Larson is a declared insider at 5 companies (board member); the most frequent names are Ecolab Inc., Republic Services, Inc. and Western Asset Inflation-Linked Income Fund. We count 38 filings; the first trade dates from 31 December 2015 and the latest from 30 September 2026.

The open-market record is one-sided, with 4 purchases worth €237k and not one sale. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Other entries cover 23 share grants and 11 option exercises.

The median purchase comes to €50k. No cluster: in 4 purchases, no other insider of the company bought within 30 days.

On 2 October 2026 came the latest disclosure, a share grant in Ecolab Inc. The most recent open-market purchase was published on 28 September 2023, 1,116 days ago. 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.
