Perestroika: trading record in brief
This profile gathers the share dealings of Perestroika in Transocean Ltd. The record holds 22 filings, for trades running from 30 January 2018 to 24 November 2025.
Purchases make up the whole of the open-market record (20 purchases, €121.3M). The amount is not disclosed for 1 filing. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The rest of the record consists of 1 share grant. In 2025 alone, the filings show 2 purchases and no sales.
Half of the purchases are above €6.3M and half below. 18 out of 19 purchases came within 30 days of a purchase by at least one other insider of the same company. Purchases made close together by different insiders form what is called a cluster. Looking at 7 purchases old enough to measure, the stock rose over the following 90 days in 29% of cases; the median change was -20.8%. This is a record of the past, not a forecast.
Most recently, on 25 November 2025, the filings show an open-market purchase worth €5.2M in Transocean Ltd. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 days. US insiders must file a Form 4 within two business days of a trade. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
