Insung Information Co., Ltd: what insiders have been doing

This page follows insider dealings at Insung Information Co., Ltd as filed with DART (FSS), a company from the Technology sector. The last twelve months, up to 10 November 2026, brought 6 filings signed by 4 insiders.

Purchases and sales both appear in the filings: 3 purchases (2 insiders) and 1 sale (1 insider). No amount is published for 4 filings, which the totals therefore leave out. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. On the buying side, the filings list 1 board member among the declarants.

The last insider purchase was made public on 2 September 2026, 69 days ago.

With 6 filings in twelve months, the company is quieter than the median of 7 filings across the 2,658 companies we follow on the same exchange. Over the whole record (from 2021), the tally stands at 26 purchases and 2 sales.

Other companies in the same sector with recent insider buying flagged by our signals: Basler Aktiengesellschaft and Lime Technologies AB (publ). These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
