How are FSLY 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 FSLY straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 84.59%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$351.63 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a FSLY straddle?

The breakeven for the FSLY straddle priced on this page is roughly $14.43 and $21.58 at expiration, derived from end-of-day chain premiums.

Current FSLY snapshot

As of June 30, 2026, spot at $18.33, ATM IV 84.59%, IV rank 42.62%, expected move 24.25%. The straddle 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 31-day expiry.

Why this straddle structure on FSLY specifically: FSLY IV at 84.59% 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 24.25% (roughly $4.45 on the underlying). The 31-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 $18.33 per share and to the trader's directional view on FSLY stock.

FSLY straddle setup

The FSLY straddle 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 $18.33, the first option leg uses a $18.00 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 31-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	$18.00	$1.90
Buy 1	Put	$18.00	$1.68

When traders use straddle on FSLY

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

FSLY thesis for this straddle

The market-implied 1-standard-deviation range for FSLY extends from approximately $13.88 on the downside to $22.78 on the upside. A FSLY 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 FSLY IV rank near 42.62% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle 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 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. 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.
