두산포트폴리오홀딩스

두산포트폴리오홀딩스 is a declared insider of 두산테스나, with filings sourced from DART (FSS). Between 5 April 2021 and 1 October 2026, the trades on record add up to 25 filings.

The filings describe grants, exercises and other transfers rather than trades on the open market. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

On 1 October 2026 came the latest disclosure, a transaction in 두산테스나. Typically, a trade is published a median of 13 days after it takes place. That lag is the time during which only the insider knows about the trade. Every figure here comes from the filings published by DART (FSS) and describes the past, not future prices; it is not investment advice.
