The period balance: money in, money out
Across the Form 4 filings submitted between Sep 3, 2025 and Oct 5, 2026, Iron Mountain Incorporated open-market activity adds up to 1 purchase worth $3k and 39 sales worth $132.0M. The net balance is $132.0M on the sell side.
Only codes P and S count, where an insider puts in or takes out their own money. A selling balance like Iron Mountain Incorporated'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
19 of the 19 sales in the table are flagged as scheduled (10b5-1 plan): signed months ahead and executed automatically, so they say nothing about what the insider thinks today. Iron Mountain'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 Oct 5, 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.

- What the efficiency hypothesis says and what it does NOT sayIf an insider's purchase is public and anyone can read it, is there any information left in it? That is the exact question that brings people here.
- 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.
