How are ENS 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 ENS butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 44.80%), the computed maximum profit is $1,076.65 per contract and the computed maximum loss is -$915.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a ENS butterfly?

The breakeven for the ENS butterfly priced on this page is roughly $240.85 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 12.84%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current ENS implied volatility affect this butterfly?

ENS ATM IV is at 44.80% with IV rank near 67.26%, which is mid-range against its 1-year history. Strategy selection depends more on directional thesis and expected move than on a strong IV signal.

ENS (EnerSys) trades in the Industrials sector, specifically Electrical Equipment & Parts, with a market capitalization of approximately $8.10B, a trailing P/E of 28.31, a beta of 1.18 versus the broader market, a 52-week range of 85-244.3, average daily share volume of 457K, a public-listing history dating back to 2004, approximately 11K full-time employees. These structural characteristics shape how ENS stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 1.18 places ENS roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. ENS pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

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 June 30, 2026, spot at $233.60, ATM IV 44.80%, IV rank 67.26%, expected move 12.84%. 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 17-day expiry.

Why this butterfly structure on ENS specifically: ENS IV at 44.80% 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 12.84% (roughly $30.00 on the underlying). The 17-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 $233.60 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 $233.60, 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 17-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	$17.80
Sell 2	Call	$230.00	$11.20
Buy 1	Call	$250.00	$3.75

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 $203.60 on the downside to $263.60 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 67.26% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on ENS should anchor more to the directional view and the expected-move geometry. 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.
