On the market, this insider has only ever bought: 55 purchases, €14k in total. 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 9 share grants.

A typical purchase (the median) is worth €119. Relative to company size, the median is 0.0001% of market cap (4 purchases with a known value). Clusters matter here: 55 out of 55 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. For 54 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 43% of cases, with a median move of -1.2%. This is a record of the past, not a forecast.

The record was last updated on 19 October 2026 with a share grant (€125) in York Water Co. The clock since the last published purchase (27 August 2026) now reads 73 days. Filings reach the SEC (Form 4) feed a median of 1 day after the trade. The legal deadline for a Form 4 is two business days after the transaction. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
