압타머사이언스: what insiders have been doing
압타머사이언스 is a Health Care company. Its directors and officers file their transactions with DART (FSS). The last twelve months, up to 2 November 2026, brought 1 filing signed by 1 insider.
The flow runs one way only: 1 insider bought (1 purchase) and nobody sold on the market. The amount is not disclosed for 1 filing. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket.
The clock since the last published purchase (26 November 2025) now reads 349 days.
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 압타머사이언스 go back to 2021, with 14 purchases and 6 sales on the open market in total.
In the same sector, recent insider purchases at Dynavox Group AB and UCB 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.
