How are FSS 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 FSS straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 34.90%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$964.84 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a FSS straddle?

The breakeven for the FSS straddle priced on this page is roughly $99.90 and $120.10 at expiration, derived from end-of-day chain premiums.

Current FSS snapshot

As of May 15, 2026, spot at $111.22, ATM IV 34.90%, IV rank 56.20%, expected move 10.01%. The straddle on FSS 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 straddle structure on FSS specifically: FSS IV at 34.90% 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 10.01% (roughly $11.13 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 FSS expiries trade a higher absolute premium for lower per-day decay. Position sizing on FSS should anchor to the underlying notional of $111.22 per share and to the trader's directional view on FSS stock.

FSS straddle setup

The FSS 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 FSS near $111.22, the first option leg uses a $110.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FSS 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 FSS shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$110.00	$6.25
Buy 1	Put	$110.00	$3.85

When traders use straddle on FSS

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

FSS thesis for this straddle

The market-implied 1-standard-deviation range for FSS extends from approximately $100.09 on the downside to $122.35 on the upside. A FSS 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 FSS IV rank near 56.20% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle thesis on FSS should anchor more to the directional view and the expected-move geometry. As a Industrials name, FSS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FSS-specific events.

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