The open-market side counts 103 purchases for €58.1M alongside 78 sales for €2.2B. Sales outweigh purchases by €2.2B. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket.

Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. For 3 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 33% of cases, with a median move of -2.8%. They describe history only and say nothing certain about the share price ahead.

Most recently, on 28 May 2025, the filings show a transaction in TaskUs, Inc. The most recent open-market purchase was published on 4 April 2023, 1,296 days ago. Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
