Sarm S.A.

Sarm S.A. discloses dealings in Desarrollos Especiales de Sistemas de Anclaje, S.A. to CNMV. Between 20 November 2024 and 20 May 2026, the trades on record add up to 29 filings.

Both buying and selling appear: 5 purchases worth €65k, against 23 sales worth €2.0M. Netting one side against the other leaves €2.0M of net selling. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Since January 2026: no purchases and 1 sale on the market.

The median purchase comes to €4,368. Relative to company size, the median is 0.012% of market cap (5 purchases with a known value). Clusters matter here: 3 out of 5 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster. After 5 purchases with a full 90-day history, the hit rate stands at 60% and the median 90-day move at +3.4%. They describe history only and say nothing certain about the share price ahead.

On 21 May 2026 came the latest disclosure, an open-market sale for €1.6M in Desarrollos Especiales de Sistemas de Anclaje, S.A. The last insider purchase was made public on 18 August 2025, 426 days ago. Filings reach the CNMV feed a median of 4 days after the trade. 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.
