RFTech Co., Ltd.: what insiders have been doing
RFTech Co., Ltd. belongs to the Technology sector. Filings by its managers are published through DART (FSS). Between 5 November 2025 and 5 November 2026, 6 insiders published 17 filings.
The record shows 5 purchases on the open market worth €56.4M, made by 2 insiders, against 6 sales worth €60.2M by 4 insiders. The amount is not disclosed for 6 filings. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Among those who bought: 1 senior executive. Biggest ticket of the year: €31.1M, sold by 시너지아이비투자 and made public on 9 April 2026.
The most recent open-market purchase was published on 5 November 2026, 5 days ago. Filings reach the DART (FSS) feed a median of 3 days after the trade. That lag is the time during which only the insider knows about the trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
With 17 filings in twelve months, the company is more active than the median of 7 filings across the 2,656 companies we follow on the same exchange. Over the whole record (from 2021), the tally stands at 10 purchases and 7 sales.
Other companies in the same sector with recent insider buying flagged by our signals: 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.
