Current WDC snapshot
As of May 15, 2026, spot at $481.44, ATM IV 81.46%, IV rank 83.96%, expected move 23.35%. The bull call spread on WDC 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 bull call spread structure on WDC specifically: WDC IV at 81.46% is rich versus its 1-year range, which makes a premium-buying WDC bull call spread relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 23.35% (roughly $112.44 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 WDC expiries trade a higher absolute premium for lower per-day decay. Position sizing on WDC should anchor to the underlying notional of $481.44 per share and to the trader's directional view on WDC stock.
WDC bull call spread setup
The WDC bull call spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With WDC near $481.44, the first option leg uses a $480.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed WDC 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 WDC shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $480.00 | $45.58 |

WDC thesis for this bull call spread
The market-implied 1-standard-deviation range for WDC extends from approximately $369.00 on the downside to $593.88 on the upside. A WDC bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on WDC, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current WDC IV rank near 83.96% 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 WDC at 81.46%. As a Technology name, WDC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to WDC-specific events.
WDC 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. WDC positions also carry Technology sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move WDC alongside the broader basket even when WDC-specific fundamentals are unchanged. Long-premium structures like a bull call spread on WDC 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 WDC chain quotes before placing a trade.
