옵트론텍: what insiders have been doing
옵트론텍, classified in the Technology sector, is a listed company. Its insiders report their share dealings to DART (FSS). Between 9 November 2025 and 9 November 2026, 8 insiders published 14 filings.
The record shows 11 purchases on the open market, made by 5 insiders, against 2 sales by 2 insiders. The amount is not disclosed for 13 filings. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The buyers include 2 major shareholders, 2 chief executives and 1 senior executive.
Compared with its exchange (2,657 companies, median 7 filings), a count of 14 filings is above the norm. Over the whole record (from 2021), the tally stands at 37 purchases and 2 sales.
The last purchase on record was published on 21 July 2026, which is 112 days ago. 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.
In the same sector, recent insider purchases at Basler Aktiengesellschaft and Lime Technologies AB (publ) also feature in our signals. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
