A story on the same day is not a cause, and a group move is not proof either. Group: the median of WELL, PLD, EQIX and SPG that day, the largest companies in AMT’s SEC industry; “moved with AMT” means the same direction and at least half the size.

What’s next · results

Before the next report: what the first day after the last four did

Six trading days after each results filing (SEC 8-K, Item 2.02). AMT reports during the trading day, so day 1 is that day’s close. Each time, day 6 ended on the same side as day 1.

AMT against four REIT peers, a year at 100

AMT is down 13.1% in a year. Welltower is up 35.1%, Equinix 27.8%, Prologis 15.2% and Simon Property 14.9%. All four did more. Weekly closes, Oct 10, 2025 = 100, on a log scale, so the same percentage move is the same height on every line.

End-of-day closes (Databento EOD), the last close of each week. The four peers are the largest US-listed companies by market value in AMT’s SEC industry (Real Estate Investment Trusts) with a year of closes. It shows what the closes did; a move here is not a cause, a forecast or a call.
