Serena Energia S.A.: what insiders have been doing
Serena Energia S.A. belongs to the Energy sector. Filings by its managers are published through CVM (Brazil). The last twelve months, up to 23 October 2026, brought 10 filings signed by 2 insiders.
Both sides are active: 4 purchases worth €872.5M and 5 sales worth €336.6M, from 1 insider and 2 insiders respectively. On balance, insiders were net buyers of €535.8M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The buyers include 1 major shareholder. One trade stands out by size: a purchase of €825.7M, disclosed on 10 December 2025.
The last insider purchase was made public on 4 February 2026, 277 days ago. Between a trade and the moment it shows up on CVM (Brazil), the median delay is 36 days. This delay matters because a trade only becomes useful information once it is public. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.
Compared with its exchange (343 companies, median 23 filings), a count of 10 filings is below the norm. Since 2022, the database holds 509 purchases and 381 sales by insiders of the company.
For comparison within the same sector, see the insider buying recorded at Compagnie de l'Odet and E.ON SE. This summary is built from CVM (Brazil) disclosures alone and does not predict where the share price will go.
