The clock since the last published purchase (20 May 2026) now reads 151 days. The median gap between trade and publication is zero days: most filings appear on the same day. For comparison, MAR article 19 gives managers three business days to notify a trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.

Elsewhere in the same sector, our signals recently picked up insider purchases at Tennant Co and Butler National Corp. Every figure here comes from the filings published by CNMV and describes the past, not future prices; it is not investment advice.
