All measured sympathy peers for TMUS

Nobody else publishes this measurement; it exists because EarningsWatcher computes it from every TMUS report, with the peer's own earnings days and heavy market days excluded.

Why trade the peer instead of TMUS itself?
Options on TMUS are expensive into the print — the expected move is priced in, and implied volatility collapses the moment results land. S has no event that day: its options are priced for a normal session, and measured across our pairs the median change in peer IV through a reporter's print is roughly zero. The sympathy trade turns TMUS's report into a position with a normal-day hurdle instead of an event-premium hurdle. New to the concept?

Frequently asked questions
Which stocks move when TMUS reports earnings?
Measured over up to ten years of TMUS's earnings days, the strongest sympathy peer is S: same direction as TMUS's reaction in 74% of 31 tracked reports, median same-day move ±2.6%. Other quality-gated peers: BEKE, AFRM, TPR — their full statistics are on the member board.
Are stocks like TMUS worth watching on its earnings day?
That is exactly what a sympathy play is: TMUS's report reprices companies with the same customers and economics, so 'stocks like TMUS' often move the same day — without an earnings event of their own. The size is usually smaller than TMUS's own move (S: ±2.6% vs a normal day ×1.6), but the peer's options carry no event premium, so there is no IV crush to pay.
Is S correlated with TMUS?
On TMUS's earnings days specifically, yes, historically: 74% same-direction over 31 events after excluding S's own earnings window and heavy market days. General day-to-day correlation is a different (weaker) question — the earnings-day link is the tradeable one.
What is a sympathy stock?
A sympathy stock moves on another company's news rather than its own — here, S reacting to TMUS's earnings. EarningsWatcher measures these relationships event by event and gates them for sample size, direction consistency and amplification; see the full guide to sympathy plays.
