In size, the median ticket on the buying side is €391k. 2 out of 5 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 median gap between a trade and its publication by SEC (Form 4) 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.
