RF Systems Co., Ltd.: what insiders have been doing
Every trade that managers of RF Systems Co., Ltd. disclose to DART (FSS) is tracked on this page. The company sits in the Industrials sector. The last twelve months, up to 23 October 2026, brought 18 filings signed by 6 insiders.
No insider sold shares on the market over the period. Instead, the filings list 17 purchases, made by 6 insiders. The totals do not cover 17 filings with an undisclosed amount. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Those buying include 4 senior executives.
The last purchase on record was published on 15 October 2026, which is 9 days ago. Typically, a trade is published a median of 6 days after it takes place. The shorter that gap, the sooner other investors can see what insiders have done.
For context, the typical company on the same exchange (median of 2,650 companies) published 7 filings over the same period, against 18 filings here. Since 2024, the database holds 30 purchases and 1 sale by insiders of the company.
For comparison within the same sector, see the insider buying recorded at Bolloré SE and Auroora Yhtiöt Oyj. This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
