Sulzer AG Stock: price and insider trades · Switzerland

Sulzer AG, classified in the Industrials sector, is a listed company based in Winterthur, Switzerland, founded in 1834. Its insiders report their share dealings to SIX SER. From 18 October 2025 to 18 October 2026, the disclosure feed for Sulzer AG logged 6 filings by 2 insiders.

The record shows 1 purchase on the open market worth €59k, made by 1 insider, against 5 sales worth €1.7M by 2 insiders. Netting one side against the other leaves €1.7M of net selling. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The buyers include 1 senior executive. One trade stands out by size: a sale of €1.1M, disclosed on 20 March 2026, or 0.021% of market capitalisation.

The last purchase on record was published on 26 November 2025, which is 326 days ago. Publication is fast: at least half of the trades appear on SIX SER on the same day. That lag is the time during which only the insider knows about the trade. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.

Compared with its exchange (178 companies, median 9 filings), a count of 6 filings is below the norm. Looking back to 2024, when coverage begins, insiders filed 4 purchases and 14 sales.

In the same sector, recent insider purchases at Tennant Co and Butler National Corp also feature in our signals. Every figure here comes from the filings published by SIX SER and describes the past, not future prices; it is not investment advice.
