What is a collar on STRL?
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 STRL snapshot
As of May 15, 2026, spot at $853.71, ATM IV 74.70%, IV rank 64.12%, expected move 21.42%. The collar on STRL 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 STRL specifically: IV regime affects collar pricing on both sides; mid-range STRL IV at 74.70% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 21.42% (roughly $182.83 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 STRL expiries trade a higher absolute premium for lower per-day decay. Position sizing on STRL should anchor to the underlying notional of $853.71 per share and to the trader's directional view on STRL stock.
STRL collar setup
The STRL 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 STRL near $853.71, the first option leg uses a $900.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed STRL 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 STRL shares for the stock leg in covered calls and collars).

STRL thesis for this collar
The market-implied 1-standard-deviation range for STRL extends from approximately $670.88 on the downside to $1,036.54 on the upside. A STRL collar hedges an existing long STRL 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 STRL IV rank near 64.12% is mid-range against its 1-year distribution, so the IV signal is neutral; the collar thesis on STRL should anchor more to the directional view and the expected-move geometry. As a Industrials name, STRL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to STRL-specific events.
STRL 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. STRL positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move STRL alongside the broader basket even when STRL-specific fundamentals are unchanged. Always rebuild the position from current STRL chain quotes before placing a trade.
