What is a butterfly on ISOU?
A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration.
Current ISOU snapshot
As of May 15, 2026, spot at $11.33, ATM IV 118.00%, expected move 33.83%. The butterfly on ISOU 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 butterfly structure on ISOU specifically: IV rank is unavailable in the current snapshot, so regime-based timing for ISOU is inferred from ATM IV at 118.00% alone, with a market-implied 1-standard-deviation move of approximately 33.83% (roughly $3.83 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 ISOU expiries trade a higher absolute premium for lower per-day decay. Position sizing on ISOU should anchor to the underlying notional of $11.33 per share and to the trader's directional view on ISOU stock.
ISOU butterfly setup
The ISOU butterfly below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With ISOU near $11.33, the first option leg uses a $10.76 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ISOU 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 ISOU shares for the stock leg in covered calls and collars).

Butterflies on ISOU are pinning bets - traders use them when they expect ISOU 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.
ISOU thesis for this butterfly
The market-implied 1-standard-deviation range for ISOU extends from approximately $7.50 on the downside to $15.16 on the upside. A ISOU long call butterfly is a pinning play: it pays maximum at the middle strike if ISOU settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. As a Energy name, ISOU options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ISOU-specific events.
ISOU 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. ISOU positions also carry Energy sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ISOU alongside the broader basket even when ISOU-specific fundamentals are unchanged. Always rebuild the position from current ISOU chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on ISOU?
- A butterfly on ISOU is the butterfly strategy applied to ISOU (stock). The strategy is structurally neutral / pin (limited-risk, limited-reward): A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration. With ISOU stock trading near $11.33, the strikes shown on this page are snapped to the nearest listed ISOU chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are ISOU 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 ISOU butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 118.00%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract. Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a ISOU butterfly?
- The breakeven for the ISOU butterfly priced on this page is no defined breakeven on the modeled curve 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 ISOU market-implied 1-standard-deviation expected move is approximately 33.83%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
