SD SYSTEM Co., Ltd: what insiders have been doing
SD SYSTEM Co., Ltd belongs to the Technology sector. Filings by its managers are published through DART (FSS). In the past year (2 November 2025 to 2 November 2026), 1 filing came from 1 insider.
Every open-market trade in the period is a purchase: 1 purchase, from 1 insider, and not a single sale. No amount is published for 1 filing, which the totals therefore leave out. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. The buyers include 1 board member.
The latest purchase dates back some time: it was published 188 days ago, on 6 May 2026.
With 1 filing in twelve months, the company is quieter than the median of 7 filings across the 2,655 companies we follow on the same exchange. Our records for SD SYSTEM Co., Ltd go back to 2021, with 18 purchases and no sales on the open market in total.
Elsewhere in the same sector, our signals recently picked up insider purchases at Basler Aktiengesellschaft and Lime Technologies AB (publ). These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
