오성첨단소재

오성첨단소재 is a declared insider of 에코볼트, with filings sourced from DART (FSS). We count 41 filings; the first trade dates from 21 May 2021 and the latest from 5 November 2026.

The open-market side counts 10 purchases alongside 13 sales. The totals exclude 23 filings filed without an amount. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. 2026 to date brings 3 purchases and 1 sale.

Clusters matter here: 1 out of 4 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

On 5 November 2026 came the latest disclosure, a transaction in 에코볼트. The most recent open-market purchase was published on 1 June 2026, 162 days ago. The median gap between a trade and its publication by DART (FSS) is 6 days. This delay matters because a trade only becomes useful information once it is public. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
