How are CFR strangle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the put strike minus the combined debit (reached at zero). Max loss equals the combined debit times 100 (reached anywhere between the two OTM strikes). Two breakevens at call-strike plus debit and put-strike minus debit. For the CFR strangle priced from the end-of-day chain at a 30-day expiry (ATM IV 26.00%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$485.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a CFR strangle?

The breakeven for the CFR strangle priced on this page is roughly $125.15 and $144.85 at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current CFR market-implied 1-standard-deviation expected move is approximately 7.45%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current CFR implied volatility affect this strangle?

CFR ATM IV is at 26.00% with IV rank near 28.48%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.

What is a strangle on CFR?

A long strangle buys an OTM call and an OTM put at offset strikes, cheaper than a straddle but requiring a larger underlying move to profit since both wings start out-of-the-money.

Current CFR snapshot

As of May 15, 2026, spot at $134.38, ATM IV 26.00%, IV rank 28.48%, expected move 7.45%. The strangle on CFR 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 34-day expiry.

Why this strangle structure on CFR specifically: CFR IV at 26.00% is on the cheap side of its 1-year range, which favors premium-buying structures like a CFR strangle, with a market-implied 1-standard-deviation move of approximately 7.45% (roughly $10.02 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated CFR expiries trade a higher absolute premium for lower per-day decay. Position sizing on CFR should anchor to the underlying notional of $134.38 per share and to the trader's directional view on CFR stock.

CFR strangle setup

The CFR strangle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With CFR near $134.38, the first option leg uses a $140.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CFR chain at a 34-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 CFR shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$140.00	$1.85
Buy 1	Put	$130.00	$3.00

When traders use strangle on CFR

Strangles on CFR are the cheaper cousin of the straddle - traders use them when they want a large directional move but are willing to give up the inner-strike sensitivity in exchange for a lower up-front debit on the CFR chain.

CFR thesis for this strangle

The market-implied 1-standard-deviation range for CFR extends from approximately $124.36 on the downside to $144.40 on the upside. A CFR long strangle is the OTM cousin of the straddle: lower up-front cost but the underlying has to travel further past either OTM strike before the position turns profitable at expiration. Current CFR IV rank near 28.48% 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 CFR at 26.00%. As a Financial Services name, CFR options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CFR-specific events.

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