COST Strangle Strategy
COST (Costco Wholesale Corporation), in the Consumer Defensive sector, (Discount Stores industry), listed on NASDAQ.
Costco Wholesale Corporation, alongside its group entities, operates membership-based retail warehouses across a broad international scope, spanning the United States, Puerto Rico, Canada, the United Kingdom, Mexico, Japan, South Korea, Australia, Spain, France, Iceland, China, and Taiwan. These outlets provide customers with an extensive array of both well-known branded and proprietary private-label products. Their vast inventory includes household staples, shelf-stable groceries, confectionery, chilled and frozen items, alcoholic beverages, tobacco, and deli selections. Furthermore, the stores stock major appliances, consumer electronics, health and beauty aids, hardware, garden and patio furniture, sporting goods, vehicle tires, toys, seasonal merchandise, office supplies, automotive maintenance products, postage services, event tickets, apparel, small kitchen appliances, home furnishings, domestic textiles, kitchenware, custom-order kiosks, and fine jewelry. Fresh departments offer meat, produce, a service deli, and bakery items. Beyond retail goods, Costco provides in-store amenities such as pharmacies, optical clinics, food courts, hearing aid centers, and tire installation facilities, in addition to managing 636 gas stations.
COST (Costco Wholesale Corporation) trades in the Consumer Defensive sector, specifically Discount Stores, with a market capitalization of approximately $422.43B, a trailing P/E of 47.85, a beta of 0.87 versus the broader market, a 52-week range of 844.06-1096.5, average daily share volume of 2.2M, a public-listing history dating back to 1986, approximately 333K full-time employees. These structural characteristics shape how COST stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.87 places COST roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 47.85 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. COST pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a strangle on COST?
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 COST snapshot
As of June 29, 2026, spot at $943.94, ATM IV 21.81%, IV rank 36.38%, expected move 6.25%. The strangle on COST 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 32-day expiry.
Why this strangle structure on COST specifically: COST IV at 21.81% 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 6.25% (roughly $59.01 on the underlying). The 32-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated COST expiries trade a higher absolute premium for lower per-day decay. Position sizing on COST should anchor to the underlying notional of $943.94 per share and to the trader's directional view on COST stock.
COST strangle setup
The COST 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 COST near $943.94, the first option leg uses a $990.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed COST chain at a 32-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 COST shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $990.00 | $8.98 |
| Buy 1 | Put | $895.00 | $6.55 |
COST strangle risk and reward

- Unbounded
- Max Loss (per contract)
- -$1,552.50
- Breakeven(s)
- $879.48, $1,005.53

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.

When traders use strangle on COST
Strangles on COST 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 COST chain.
COST thesis for this strangle
The market-implied 1-standard-deviation range for COST extends from approximately $884.93 on the downside to $1,002.95 on the upside. A COST 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 COST IV rank near 36.38% is mid-range against its 1-year distribution, so the IV signal is neutral; the strangle thesis on COST should anchor more to the directional view and the expected-move geometry. As a Consumer Defensive name, COST options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to COST-specific events.
COST 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. COST positions also carry Consumer Defensive sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move COST alongside the broader basket even when COST-specific fundamentals are unchanged. Always rebuild the position from current COST chain quotes before placing a trade.
Frequently asked questions
- What is a strangle on COST?
- A strangle on COST is the strangle strategy applied to COST (stock).

- How are COST 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).
