에스와이: what insiders have been doing

에스와이 belongs to the Construction sector. Filings by its managers are published through DART (FSS). Between 2 November 2025 and 2 November 2026, 2 insiders published 7 filings.

The record shows 3 purchases on the open market, made by 2 insiders, against 4 sales by 1 insider. No amount is published for 7 filings, which the totals therefore leave out. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The buyers include 1 major shareholder and 1 chief executive.

The last insider purchase was made public on 18 June 2026, 144 days ago. Filings reach the DART (FSS) feed a median of 6 days after the trade. This delay matters because a trade only becomes useful information once it is public. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning.

Compared with its exchange (2,655 companies, median 7 filings), a count of 7 filings is typical. Looking back to 2021, when coverage begins, insiders filed 28 purchases and 6 sales.

These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
