Mark Sheldon, listed as senior executive, appears in our data through filings on Sidetrade shares, published by AMF. We count 5 filings; the first trade dates from 16 December 2024 and the latest from 18 May 2026.

In open-market terms, that means 3 purchases worth €56k on one side and 1 sale worth €86k on the other. Taken together, the sales exceed the purchases by €30k. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. In 2026 alone, the filings show 2 purchases and no sales.

The median purchase comes to €20k. Clusters matter here: 1 out of 3 purchases overlapped with buying by a colleague within 30 days. 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 67% of cases, with a median move of +15.1%. These figures describe past trades and do not predict future prices.

On 18 May 2026 came the latest disclosure, an open-market purchase for €9,858 in Sidetrade. Typically, a trade is published a median of 6 days after it takes place. The legal deadline for notifying a trade is three business days (MAR article 19). Source: insider filings from AMF. Past trades are no guide to future returns.
