TSI Co., Ltd.: what insiders have been doing
TSI Co., Ltd. belongs to the Industrials sector. Filings by its managers are published through DART (FSS). Over the twelve months to 22 October 2026, 15 filings were filed, from 5 insiders.
The flow runs one way only: 4 insiders bought (10 purchases totalling €117k) and nobody sold on the market. The totals do not cover 6 filings with an undisclosed amount. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Among those who bought: 2 senior executives and 2 chief executives. Biggest ticket of the year: €32k, bought by 표인식 and made public on 14 May 2026 (0.085% of market cap).
In the case of 2 purchases, another manager of the company was buying within the same 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. The most recent open-market purchase was published on 24 July 2026, 108 days ago. The median gap between a trade and its publication by DART (FSS) is 1 day. Until a filing is published, the market cannot know about the trade.
Across the 2,650 companies tracked on its exchange, the median is 7 filings; at 15 filings, this issuer sits above that mark. The full history, which starts in 2021, counts 29 purchases against 24 sales.
Elsewhere in the same sector, our signals recently picked up insider purchases at Bolloré SE and Deceuninck. Source: insider filings from DART (FSS). Past trades are no guide to future returns.
