데이터스트림즈: what insiders have been doing

This page follows insider dealings at 데이터스트림즈 as filed with DART (FSS), a company from the Technology sector. Between 8 November 2025 and 8 November 2026, 1 insider published 1 filing.

There is no open-market purchase to report; the filings show 1 sale by 1 insider. The totals do not cover 1 filing with an undisclosed amount.

For context, the typical company on the same exchange (median of 2,648 companies) published 7 filings over the same period, against 1 filing here. The full history, which starts in 2021, counts 7 purchases against 1 sale.

Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning.

In the same sector, recent insider purchases at Core Scientific, Inc./tx and Gitlab Inc. 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.
