How are FSLY 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 FSLY strangle priced from the end-of-day chain at a 30-day expiry (ATM IV 86.29%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$277.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a FSLY strangle?

The breakeven for the FSLY strangle priced on this page is roughly $14.23 and $21.78 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 FSLY market-implied 1-standard-deviation expected move is approximately 24.74%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current FSLY implied volatility affect this strangle?

Current FSLY snapshot

As of June 29, 2026, spot at $18.05, ATM IV 86.29%, IV rank 44.16%, expected move 24.74%. The strangle on FSLY 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 32-day expiry.

Why this strangle structure on FSLY specifically: FSLY IV at 86.29% 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 24.74% (roughly $4.47 on the underlying). The 32-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated FSLY expiries trade a higher absolute premium for lower per-day decay. Position sizing on FSLY should anchor to the underlying notional of $18.05 per share and to the trader's directional view on FSLY stock.

FSLY strangle setup

The FSLY 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 FSLY near $18.05, 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 FSLY chain at a 32-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 FSLY shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$19.00	$1.58
Buy 1	Put	$17.00	$1.20

When traders use strangle on FSLY

Strangles on FSLY 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 FSLY chain.

FSLY thesis for this strangle

The market-implied 1-standard-deviation range for FSLY extends from approximately $13.58 on the downside to $22.52 on the upside. A FSLY 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 FSLY IV rank near 44.16% is mid-range against its 1-year distribution, so the IV signal is neutral; the strangle thesis on FSLY should anchor more to the directional view and the expected-move geometry. As a Technology name, FSLY options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FSLY-specific events.

FSLY 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. FSLY positions also carry Technology sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move FSLY alongside the broader basket even when FSLY-specific fundamentals are unchanged. Always rebuild the position from current FSLY chain quotes before placing a trade.
