Denis Oleary: trading record in brief
Denis Oleary (board member) discloses dealings in 2 companies, chiefly CrowdStrike Holdings, Inc. and Fiserv Inc. Between 19 May 2021 and 18 September 2026, the trades on record add up to 52 filings.
On the open market, the record shows 3 purchases worth €3.4M and 18 sales worth €16.0M. Sales outweigh purchases by €12.6M. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Outside the open market, there are 19 share grants. So far in 2026, the count stands at no purchases and 16 sales.
The median purchase comes to €1.2M. 1 out of 3 purchases came within 30 days of a purchase by at least one other insider of the same company. Purchases made close together by different insiders form what is called a cluster.
The newest entry dates from 21 September 2026: a share grant, in CrowdStrike Holdings, Inc. The last purchase on record was published on 23 November 2021, which is 1,790 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 days. The legal deadline for a Form 4 is two business days after the transaction. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
