STX snapshot
As of August 14, 2026, spot at $971.05, ATM IV 72.27%, IV rank 48.08%, expected move 20.72%. The bull call spread on STX below is built from the August 14, 2026 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 bull call spread structure on STX specifically: STX IV at 72.27% 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 20.72% (roughly $201.19 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 $971.05 per share and to the trader's directional view on STX stock.
STX bull call spread setup
The STX bull call spread below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With STX at $971.05 on that close, the first option leg uses a $970.00 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).

|---|---|---|---|
| Buy 1 | Call | $970.00 | $76.80 |
| Sell 1 | Call | $1,020.00 | $56.60 |

STX thesis for this bull call spread
The market-implied 1-standard-deviation range for STX extends from approximately $769.86 on the downside to $1,172.24 on the upside. A STX bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on STX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current STX IV rank near 48.08% is mid-range against its 1-year distribution, so the IV signal is neutral; the bull call spread thesis on STX should anchor more to the directional view and the expected-move geometry. 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 bull call spread positions are structurally moderately bullish; 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 bull call spread 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.
