How are MUX straddle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit. For the MUX straddle priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 58.90%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$128.96 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a MUX straddle?

The breakeven for the MUX straddle priced on this page is roughly $17.65 and $20.35 at expiration, derived from the August 14, 2026 end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk.

MUX snapshot

As of August 14, 2026, spot at $18.84, ATM IV 58.90%, IV rank 27.30%, expected move 16.89%. The straddle on MUX below is built from the August 14, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 7-day expiry.

Why this straddle structure on MUX specifically: MUX IV at 58.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a MUX straddle, with a market-implied 1-standard-deviation move of approximately 16.89% (roughly $3.18 on the underlying). The 7-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated MUX expiries trade a higher absolute premium for lower per-day decay. Position sizing on MUX should anchor to the underlying notional of $18.84 per share and to the trader's directional view on MUX stock.

MUX straddle setup

The MUX straddle below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With MUX at $18.84 on that close, the first option leg uses a $19.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MUX chain at a 7-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 MUX shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$19.00	$0.65
Buy 1	Put	$19.00	$0.70

When traders use straddle on MUX

Straddles on MUX are pure-volatility plays that profit from large moves in either direction; traders typically buy MUX straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.

MUX thesis for this straddle

The market-implied 1-standard-deviation range for MUX extends from approximately $15.66 on the downside to $22.02 on the upside. A MUX long straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current MUX IV rank near 27.30% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on MUX at 58.90%. As a Basic Materials name, MUX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MUX-specific events.

MUX straddle positions are structurally neutral / high-volatility (long premium); 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. MUX positions also carry Basic Materials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MUX alongside the broader basket even when MUX-specific fundamentals are unchanged. Always rebuild the position from current MUX chain quotes before placing a trade.
