Fine Semitech Corp.: what insiders have been doing
Every trade that managers of Fine Semitech Corp. disclose to DART (FSS) is tracked on this page. The company sits in the Technology sector. From 1 November 2025 to 1 November 2026, the disclosure feed for Fine Semitech Corp. logged 10 filings by 6 insiders.
Open-market activity splits into 6 purchases totalling €30.7M and 1 sale; 4 insiders sit on the buying side and 1 insider on the selling side. The totals exclude 3 filings filed without an amount. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. At €29.3M, the purchase published on 12 March 2026 by 삼성자산운용 is the largest of the period (9.6% of market cap). On the buying side, the filings list 3 chief executives among the declarants.
For context, the typical company on the same exchange (median of 2,655 companies) published 7 filings over the same period, against 10 filings here. Looking back to 2021, when coverage begins, insiders filed 24 purchases and 1 sale.
The data flag 3 purchases as part of a group of insiders buying within 30 days of each other. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. The clock since the last published purchase (28 April 2026) now reads 196 days. The median gap between a trade and its publication by DART (FSS) is 4 days. That lag is the time during which only the insider knows about the trade.
For comparison within the same sector, see the insider buying recorded at Basler Aktiengesellschaft and Lime Technologies AB (publ). This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
