Entry is the close on the day after publication, the first price a reader could act on. Prices in the listing currency. Past moves are not a forecast.
Filings by Paul Edward Walker span 13 companies, the busiest being Allakos Inc., Korro Bio, Inc. and NeueHealth, Inc. Over a trading history stretching from 28 June 2021 to 10 March 2026, the count stands at 17 filings.
The open-market side counts 6 purchases for €11.5M alongside 2 sales for €44k. The amount is not disclosed for 2 filings. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Besides market trades, the filings include 1 share grant. In 2026 alone, the filings show 1 purchase and no sales.
A typical purchase (the median) is worth €2.0M. 5 out of 6 purchases came within 30 days of a purchase by at least one other insider of the same company. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.
The newest entry dates from 12 March 2026: an open-market purchase of €2.0M, in Korro Bio, Inc. The median gap between a trade and its publication by SEC (Form 4) is 2 days.
