The period balance: money in, money out
In the Form 4 filings submitted between Dec 2, 2025 and Apr 15, 2026 there is not one open-market purchase of A. O. Smith Corporation: 2 sales worth $111k and zero dollars bought.
Only codes P and S count, where an insider puts in or takes out their own money. A selling balance like A. O. Smith Corporation's is the norm in the S&P 500, where much of the pay comes as stock. It is not a recommendation to buy or sell: it is what was filed.

How to read this data
None of the 2 sales in the table is flagged as scheduled (10b5-1 plan), the kind signed months ahead and executed automatically. A. O. Smith has no open-market purchase (code P) in the history, the most common case in the S&P 500: insiders are already paid in stock. The latest filing is from Apr 15, 2026, and a Form 4 arrives up to two business days after the trade.
20 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.

- Who really moves the market: the types of investorWho sits on the other side of each order, and where a company's own insiders fit among them.
- 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.
