What is the breakeven for a STX long put?

The breakeven for the STX long put priced on this page is roughly $730.75 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.

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.

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 long put 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 long put structure on STX specifically: STX IV at 79.91% is rich versus its 1-year range, which makes a premium-buying STX long put 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 long put setup

The STX long put 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 $800.00 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	Put	$800.00	$69.25

Long puts on STX hedge an existing long STX stock position or express a bearish view with defined risk; position sizing typically scales the put notional to the underlying STX exposure being hedged.

STX thesis for this long put

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 put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long STX position with one put per 100 shares held. 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 long put positions are structurally bearish; 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. Long-premium structures like a long put on STX are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current STX chain quotes before placing a trade.
