Filings by Michael D. Ohalleran span 5 companies, the busiest being Aon plc, CareFusion Corp and Ryan Specialty Holdings, Inc. We count 95 filings; the first trade dates from 1 December 2005 and the latest from 28 April 2026.

In open-market terms, that means 7 purchases worth €5.4M on one side and 2 sales worth €6.4M on the other. Taken together, the sales exceed the purchases by €1.0M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Besides market trades, the filings include 25 share grants and 32 option exercises.

Half of the purchases are above €257k and half below. Clusters matter here: 7 out of 7 purchases overlapped with buying by a colleague within 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

The latest filing, published on 30 April 2026, reports a share grant in Ryan Specialty Holdings, Inc. The clock since the last published purchase (17 November 2022) now reads 1,437 days. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
