CTK Co., Ltd Stock: price and insider trades · South Korea

CTK Co., Ltd is a Industrials company. Its directors and officers file their transactions with DART (FSS). The last twelve months, up to 23 October 2026, brought 12 filings signed by 2 insiders.

The record shows 2 purchases on the open market, made by 2 insiders, against 4 sales by 1 insider. 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. On the buying side, the filings list 1 major shareholder and 1 senior executive among the declarants.

For context, the typical company on the same exchange (median of 2,650 companies) published 7 filings over the same period, against 12 filings here. Looking back to 2021, when coverage begins, insiders filed 2 purchases and 46 sales.

The most recent open-market purchase was published on 12 June 2026, 151 days ago. Typically, a trade is published a median of 4 days after it takes place. Until a filing is published, the market cannot know about the trade. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives.

In the same sector, recent insider purchases at Bolloré SE and Auroora Yhtiöt Oyj also feature in our signals. Every figure here comes from the filings published by DART (FSS) and describes the past, not future prices; it is not investment advice.
