The open-market side counts 8 purchases for €84k alongside 2 sales for €6,030. On balance, insiders were net buyers of €78k.

In 2026 alone, the filings show 5 purchases and no sales.

A typical purchase (the median) is worth €12k. Measured against the company's value, the median purchase equals 0.074% of market capitalisation, across 5 purchases where it is known. 7 out of 8 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.

Most recently, on 30 September 2026, the filings show an open-market purchase worth €14k in Hyperscale Data, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
