Current TMUS snapshot

As of May 15, 2026, spot at $185.34, ATM IV 29.04%, IV rank 45.94%, expected move 8.32%. The butterfly on TMUS below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 28-day expiry.

Why this butterfly structure on TMUS specifically: TMUS IV at 29.04% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 8.32% (roughly $15.43 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated TMUS expiries trade a higher absolute premium for lower per-day decay. Position sizing on TMUS should anchor to the underlying notional of $185.34 per share and to the trader's directional view on TMUS stock.

TMUS butterfly setup

The TMUS butterfly below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With TMUS near $185.34, the first option leg uses a $175.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TMUS chain at a 28-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 TMUS shares for the stock leg in covered calls and collars).

Buy 1	Call	$175.00	$12.65

When traders use butterfly on TMUS

Butterflies on TMUS are pinning bets - traders use them when they expect TMUS to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.

TMUS thesis for this butterfly

The market-implied 1-standard-deviation range for TMUS extends from approximately $169.91 on the downside to $200.77 on the upside. A TMUS long call butterfly is a pinning play: it pays maximum at the middle strike if TMUS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current TMUS IV rank near 45.94% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on TMUS should anchor more to the directional view and the expected-move geometry. As a Communication Services name, TMUS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TMUS-specific events.

TMUS butterfly positions are structurally neutral / pin (limited-risk, limited-reward); the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. TMUS positions also carry Communication Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move TMUS alongside the broader basket even when TMUS-specific fundamentals are unchanged. Always rebuild the position from current TMUS chain quotes before placing a trade.
