COST (Costco Wholesale Corporation) trades in the Consumer Defensive sector, specifically Discount Stores, with a market capitalization of approximately $458.33B, a trailing P/E of 53.65, a beta of 0.91 versus the broader market, a 52-week range of 844.06-1067.08, average daily share volume of 1.8M, 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 0.91 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 53.65 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 bear put spread on COST?
A bear put spread buys an at-the-money put and sells an out-of-the-money put at a lower strike for defined risk and defined reward bounded by the strike width.
Current COST snapshot
As of May 15, 2026, spot at $1,048.80, ATM IV 26.48%, IV rank 67.69%, expected move 7.59%. The bear put spread 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 28-day expiry.
Why this bear put spread structure on COST specifically: COST IV at 26.48% 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 7.59% (roughly $79.62 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 COST expiries trade a higher absolute premium for lower per-day decay. Position sizing on COST should anchor to the underlying notional of $1,048.80 per share and to the trader's directional view on COST stock.
COST bear put spread setup
The COST bear put 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 COST near $1,048.80, the first option leg uses a $1,050.00 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 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 COST shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Put | $1,050.00 | $30.78 |
| Sell 1 | Put | $995.00 | $10.63 |

COST thesis for this bear put spread
The market-implied 1-standard-deviation range for COST extends from approximately $969.18 on the downside to $1,128.42 on the upside. A COST bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on COST, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current COST IV rank near 67.69% is mid-range against its 1-year distribution, so the IV signal is neutral; the bear put spread 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 bear put spread positions are structurally moderately 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. 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. Long-premium structures like a bear put spread on COST 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 COST chain quotes before placing a trade.
