Seoul Viosys Co., Ltd: what insiders have been doing
Seoul Viosys Co., Ltd belongs to the Technology sector. Filings by its managers are published through DART (FSS). The last twelve months, up to 1 November 2026, brought 3 filings signed by 2 insiders.
Every open-market trade in the period is a purchase: 2 purchases, from 1 insider, and not a single sale. The totals do not cover 2 filings with an undisclosed amount. Unlike grants, an open-market purchase is paid for by the insider, at the market price.
The latest purchase dates back some time: it was published 323 days ago, on 22 December 2025.
Across the 2,655 companies tracked on its exchange, the median is 7 filings; at 3 filings, this issuer sits below that mark. The full history, which starts in 2021, counts 14 purchases against no sales.
For comparison within the same sector, see the insider buying recorded at 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.
