How are IONS 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 IONS straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 36.60%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$948.85 per contract. Live intraday quotes will differ as the chain moves through the trading session.

Current IONS snapshot

As of May 15, 2026, spot at $73.87, ATM IV 36.60%, IV rank 5.37%, expected move 10.49%. The straddle on IONS 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 63-day expiry.

Why this straddle structure on IONS specifically: IONS IV at 36.60% is on the cheap side of its 1-year range, which favors premium-buying structures like a IONS straddle, with a market-implied 1-standard-deviation move of approximately 10.49% (roughly $7.75 on the underlying). The 63-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated IONS expiries trade a higher absolute premium for lower per-day decay. Position sizing on IONS should anchor to the underlying notional of $73.87 per share and to the trader's directional view on IONS stock.

IONS straddle setup

The IONS 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 IONS near $73.87, the first option leg uses a $75.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed IONS chain at a 63-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 IONS shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$75.00	$4.30
Buy 1	Put	$75.00	$5.20

When traders use straddle on IONS

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

IONS thesis for this straddle

The market-implied 1-standard-deviation range for IONS extends from approximately $66.12 on the downside to $81.62 on the upside. A IONS 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 IONS IV rank near 5.37% 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 IONS at 36.60%. As a Healthcare name, IONS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to IONS-specific events.

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