How are FSLY butterfly max profit and max loss calculated?

Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit. For the FSLY butterfly priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 73.54%), the computed maximum profit is $156.86 per contract and the computed maximum loss is $7.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a FSLY butterfly?

The breakeven for the FSLY butterfly priced on this page is no defined breakeven on the modeled curve 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. The FSLY market-implied 1-standard-deviation expected move in the same options snapshot is approximately 21.08%; 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 butterfly?

FSLY snapshot

As of August 14, 2026, spot at $30.14, ATM IV 73.54%, IV rank 28.43%, expected move 21.08%. The butterfly on FSLY 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 28-day expiry.

Why this butterfly structure on FSLY specifically: FSLY IV at 73.54% is on the cheap side of its 1-year range, which favors premium-buying structures like a FSLY butterfly, with a market-implied 1-standard-deviation move of approximately 21.08% (roughly $6.35 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 FSLY expiries trade a higher absolute premium for lower per-day decay. Position sizing on FSLY should anchor to the underlying notional of $30.14 per share and to the trader's directional view on FSLY stock.

FSLY butterfly setup

The FSLY butterfly 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 FSLY at $30.14 on that close, the first option leg uses a $28.50 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 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 FSLY shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$28.50	$3.20
Sell 2	Call	$30.00	$2.55
Buy 1	Call	$31.50	$1.83

When traders use butterfly on FSLY

Butterflies on FSLY are pinning bets - traders use them when they expect FSLY 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.

FSLY thesis for this butterfly

The market-implied 1-standard-deviation range for FSLY extends from approximately $23.79 on the downside to $36.49 on the upside. A FSLY long call butterfly is a pinning play: it pays maximum at the middle strike if FSLY settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current FSLY IV rank near 28.43% 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 FSLY at 73.54%. 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 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. 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.
