The period balance: money in, money out
Across the Form 4 filings submitted between Sep 12, 2025 and Sep 14, 2026, The Trade Desk, Inc. open-market activity adds up to 3 purchases worth $148.1M and 3 sales worth $5.9M. The net balance is $142.2M on the buy side.
Only codes P and S count, where an insider puts in or takes out their own money. A buying balance like The Trade Desk, Inc.'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
None of the 3 sales in the table is flagged as scheduled (10b5-1 plan), the kind signed months ahead and executed automatically. Trade Desk's 3 open-market purchases (code P) are the rare signal: insiders are already paid in stock, so buying more means putting in their own money. The latest filing is from Sep 14, 2026, and a Form 4 arrives up to two business days after the trade.
19 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.
