How are HEI 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 HEI straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 42.40%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$2,979.45 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a HEI straddle?

The breakeven for the HEI straddle priced on this page is roughly $260.10 and $319.90 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 HEI market-implied 1-standard-deviation expected move is approximately 12.16%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current HEI implied volatility affect this straddle?

HEI ATM IV is at 42.40% with IV rank near 82.74%, which is elevated relative to its 1-year range. Premium-selling structures (covered call, cash-secured put, iron condor) generally look more attractive when IV rank is high; premium-buying structures (long call, long put, debit spreads) are more expensive in that regime.

HEI (HEICO Corporation) trades in the Industrials sector, specifically Aerospace & Defense, with a market capitalization of approximately $40.61B, a trailing P/E of 57.07, a beta of 0.95 versus the broader market, a 52-week range of 256.11-361.69, average daily share volume of 727K, a public-listing history dating back to 1980, approximately 10K full-time employees. These structural characteristics shape how HEI stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 0.95 places HEI roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 57.07 is on the rich side, which tends to correlate with higher earnings-window IV expansion as the market debates whether forward growth supports the multiple. HEI pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a straddle on HEI?

A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.

Current HEI snapshot

As of May 15, 2026, spot at $288.65, ATM IV 42.40%, IV rank 82.74%, expected move 12.16%. The straddle on HEI 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 HEI specifically: HEI IV at 42.40% is rich versus its 1-year range, which makes a premium-buying HEI straddle relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 12.16% (roughly $35.09 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 HEI expiries trade a higher absolute premium for lower per-day decay. Position sizing on HEI should anchor to the underlying notional of $288.65 per share and to the trader's directional view on HEI stock.

HEI straddle setup

The HEI 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 HEI near $288.65, the first option leg uses a $290.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed HEI 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 HEI shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$290.00	$15.00
Buy 1	Put	$290.00	$14.90

When traders use straddle on HEI

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

HEI thesis for this straddle

The market-implied 1-standard-deviation range for HEI extends from approximately $253.56 on the downside to $323.74 on the upside. A HEI 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 HEI IV rank near 82.74% 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 HEI at 42.40%. As a Industrials name, HEI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to HEI-specific events.

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