What is a butterfly on ENS?
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 ENS snapshot
As of May 15, 2026, spot at $235.81, ATM IV 47.30%, IV rank 80.53%, expected move 13.56%. The butterfly on ENS 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 ENS specifically: ENS IV at 47.30% is rich versus its 1-year range, which makes a premium-buying ENS butterfly relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 13.56% (roughly $31.98 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 ENS expiries trade a higher absolute premium for lower per-day decay. Position sizing on ENS should anchor to the underlying notional of $235.81 per share and to the trader's directional view on ENS stock.
ENS butterfly setup
The ENS 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 ENS near $235.81, the first option leg uses a $220.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ENS 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 ENS shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $220.00 | $22.75 |
| Sell 2 | Call | $240.00 | $11.15 |
| Buy 1 | Call | $250.00 | $7.50 |

When traders use butterfly on ENS
Butterflies on ENS are pinning bets - traders use them when they expect ENS 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.
ENS thesis for this butterfly
The market-implied 1-standard-deviation range for ENS extends from approximately $203.83 on the downside to $267.79 on the upside. A ENS long call butterfly is a pinning play: it pays maximum at the middle strike if ENS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current ENS IV rank near 80.53% sits in the upper third of its 1-year distribution, which historically reverts; this raises the bar for premium-buying structures and lowers it for premium-selling structures on ENS at 47.30%. As a Industrials name, ENS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ENS-specific events.
ENS 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. ENS positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ENS alongside the broader basket even when ENS-specific fundamentals are unchanged. Always rebuild the position from current ENS chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on ENS?

- How are ENS butterfly max profit and max loss calculated?

- What is the breakeven for a ENS butterfly?
- The breakeven for the ENS butterfly priced on this page is roughly $227.95 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 ENS market-implied 1-standard-deviation expected move is approximately 13.56%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
