Montana Aerospace AG Stock: price and insider trades · Switzerland

Every trade that managers of Montana Aerospace AG disclose to SIX SER is tracked on this page. The company sits in the Aerospace & Defense sector. From 18 October 2025 to 18 October 2026, the disclosure feed for Montana Aerospace AG logged 18 filings by 4 insiders.

Purchases and sales both appear in the filings: 7 purchases (3 insiders, €394k) and 11 sales (3 insiders, €35.2M). On balance, insiders were net sellers of €34.8M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. At €33.1M, the sale published on 14 January 2026 is the largest of the period. Those buying include 3 senior executives.

In the case of 4 purchases, another manager of the company was buying within the same 30 days. Purchases made close together by different insiders form what is called a cluster. The clock since the last published purchase (8 October 2026) now reads 9 days. Half of the filings or more reach the SIX SER feed on the day of the trade. The shorter that gap, the sooner other investors can see what insiders have done. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.

For context, the typical company on the same exchange (median of 177 companies) published 9 filings over the same period, against 18 filings here. Our records for Montana Aerospace AG go back to 2023, with 24 purchases and 32 sales on the open market in total.

Elsewhere in the same sector, our signals recently picked up insider purchases at Heico Corp. This summary is built from SIX SER disclosures alone and does not predict where the share price will go.
