How are STX strangle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the put strike minus the combined debit (reached at zero). Max loss equals the combined debit times 100 (reached anywhere between the two OTM strikes). Two breakevens at call-strike plus debit and put-strike minus debit. For the STX strangle priced from the end-of-day chain at a 30-day expiry (ATM IV 79.91%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$10,455.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a STX strangle?

The breakeven for the STX strangle priced on this page is roughly $655.45 and $944.55 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 STX market-implied 1-standard-deviation expected move is approximately 22.91%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current STX implied volatility affect this strangle?

STX ATM IV is at 79.91% with IV rank near 87.83%, 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.

STX (Seagate Technology Holdings plc) trades in the Technology sector, specifically Computer Hardware, with a market capitalization of approximately $183.27B, a trailing P/E of 75.96, a beta of 2.01 versus the broader market, a 52-week range of 103.73-841.31, average daily share volume of 4.0M, a public-listing history dating back to 2002, approximately 30K full-time employees. These structural characteristics shape how STX stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 2.01 indicates STX has historically moved more than the broader market, amplifying both the directional payoff and the realized volatility relative to an index-equivalent position. The trailing P/E of 75.96 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. STX pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a strangle on STX?

A long strangle buys an OTM call and an OTM put at offset strikes, cheaper than a straddle but requiring a larger underlying move to profit since both wings start out-of-the-money.

Current STX snapshot

As of May 15, 2026, spot at $797.78, ATM IV 79.91%, IV rank 87.83%, expected move 22.91%. The strangle on STX 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 28-day expiry.

Why this strangle structure on STX specifically: STX IV at 79.91% is rich versus its 1-year range, which makes a premium-buying STX strangle relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 22.91% (roughly $182.78 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated STX expiries trade a higher absolute premium for lower per-day decay. Position sizing on STX should anchor to the underlying notional of $797.78 per share and to the trader's directional view on STX stock.

STX strangle setup

The STX strangle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With STX near $797.78, the first option leg uses a $840.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed STX chain at a 28-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 STX shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$840.00	$54.45
Buy 1	Put	$760.00	$50.10

When traders use strangle on STX

Strangles on STX are the cheaper cousin of the straddle - traders use them when they want a large directional move but are willing to give up the inner-strike sensitivity in exchange for a lower up-front debit on the STX chain.

STX thesis for this strangle

The market-implied 1-standard-deviation range for STX extends from approximately $615.00 on the downside to $980.56 on the upside. A STX long strangle is the OTM cousin of the straddle: lower up-front cost but the underlying has to travel further past either OTM strike before the position turns profitable at expiration. Current STX IV rank near 87.83% 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 STX at 79.91%. As a Technology name, STX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to STX-specific events.

STX strangle positions are structurally neutral / high-volatility (long premium, OTM); 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. STX positions also carry Technology sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move STX alongside the broader basket even when STX-specific fundamentals are unchanged. Always rebuild the position from current STX chain quotes before placing a trade.
