WSI Co., Ltd.: what insiders have been doing
WSI Co., Ltd. is a Banks company. Its directors and officers file their transactions with DART (FSS). Over the twelve months to 31 October 2026, 15 filings were filed, from 6 insiders.
Purchases and sales both appear in the filings: 5 purchases (3 insiders, €11k) and 9 sales (3 insiders). No amount is published for 13 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. Biggest ticket of the year: €11k, bought by 안진수 and made public on 6 March 2026 (0.034% of market cap). Those buying include 1 major shareholder and 1 board member.
The clock since the last published purchase (25 June 2026) now reads 137 days. The median gap between a trade and its publication by DART (FSS) is 9 days. The shorter that gap, the sooner other investors can see what insiders have done. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning.
With 15 filings in twelve months, the company is more active than the median of 7 filings across the 2,655 companies we follow on the same exchange. The full history, which starts in 2021, counts 27 purchases against 12 sales.
Elsewhere in the same sector, our signals recently picked up insider purchases at BAWAG Group AG and ASR Nederland N.V. Source: insider filings from DART (FSS). Past trades are no guide to future returns.
