The period balance: money in, money out
In the Form 4 filings submitted between Oct 31, 2025 and Aug 13, 2026 there is not one open-market sale of Constellation Energy Corporation: 1 open-market purchase worth $418k and zero dollars sold.
Only codes P and S count, where an insider puts in or takes out their own money. A buying balance like Constellation Energy Corporation's is the less common case in the S&P 500: its insiders are already paid in stock and still put in their own money. It is not a recommendation to buy or sell: it is what was filed.

How to read this data
Constellation Energy's single open-market purchase (code P) is the rare signal: insiders are already paid in stock, so buying more means putting in their own money. The latest filing is from Aug 13, 2026, and a Form 4 arrives up to two business days after the trade.
2 of the 20 rows in the table carry footnotes from the Form 4 itself, folded into the code column and copied verbatim; a row with no footnote means the filing has none.

- Supply, demand and price: why it rises and falls constantlyHow a piece of news ends up inside the price, and why the reaction to a filed sale is rarely the one you would expect.
