WLK (Westlake Corporation) trades in the Basic Materials sector, specifically Chemicals - Specialty, with a market capitalization of approximately $11.82B, a beta of 0.67 versus the broader market, a 52-week range of 56.33-124.23, average daily share volume of 1.3M, a public-listing history dating back to 2004, approximately 16K full-time employees. These structural characteristics shape how WLK stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

What is a collar on WLK?
A collar pairs long stock with a protective out-of-the-money put financed by a short out-of-the-money call, capping both tails of the position around the current spot.
Current WLK snapshot
As of May 15, 2026, spot at $88.98, ATM IV 50.80%, IV rank 41.09%, expected move 14.56%. The collar on WLK 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 34-day expiry.
Why this collar structure on WLK specifically: IV regime affects collar pricing on both sides; mid-range WLK IV at 50.80% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 14.56% (roughly $12.96 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated WLK expiries trade a higher absolute premium for lower per-day decay. Position sizing on WLK should anchor to the underlying notional of $88.98 per share and to the trader's directional view on WLK stock.
WLK collar setup
The WLK collar below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With WLK near $88.98, the first option leg uses a $95.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed WLK chain at a 34-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 WLK shares for the stock leg in covered calls and collars).

| Buy 100 shares | Stock | $88.98 | long |
| Sell 1 | Call | $95.00 | $2.98 |
| Buy 1 | Put | $85.00 | $3.90 |

WLK thesis for this collar
The market-implied 1-standard-deviation range for WLK extends from approximately $76.02 on the downside to $101.94 on the upside. A WLK collar hedges an existing long WLK position with a protective put while financing the put cost via a short call; when the premiums roughly offset, the collar acts as a near-zero-cost insurance band around the current spot. Current WLK IV rank near 41.09% is mid-range against its 1-year distribution, so the IV signal is neutral; the collar thesis on WLK should anchor more to the directional view and the expected-move geometry. As a Basic Materials name, WLK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to WLK-specific events.
WLK collar positions are structurally neutral (protective); 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. WLK positions also carry Basic Materials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move WLK alongside the broader basket even when WLK-specific fundamentals are unchanged. Always rebuild the position from current WLK chain quotes before placing a trade.
