Current SLG snapshot
As of May 15, 2026, spot at $42.52, ATM IV 46.20%, IV rank 36.36%, expected move 13.25%. The collar on SLG 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 217-day expiry.
Why this collar structure on SLG specifically: IV regime affects collar pricing on both sides; mid-range SLG IV at 46.20% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 13.25% (roughly $5.63 on the underlying). The 217-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SLG expiries trade a higher absolute premium for lower per-day decay. Position sizing on SLG should anchor to the underlying notional of $42.52 per share and to the trader's directional view on SLG stock.
SLG collar setup
The SLG 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 SLG near $42.52, the first option leg uses a $45.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SLG chain at a 217-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 SLG shares for the stock leg in covered calls and collars).

SLG thesis for this collar
The market-implied 1-standard-deviation range for SLG extends from approximately $36.89 on the downside to $48.15 on the upside. A SLG collar hedges an existing long SLG 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 SLG IV rank near 36.36% is mid-range against its 1-year distribution, so the IV signal is neutral; the collar thesis on SLG should anchor more to the directional view and the expected-move geometry. As a Real Estate name, SLG options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SLG-specific events.
SLG 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. SLG positions also carry Real Estate sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SLG alongside the broader basket even when SLG-specific fundamentals are unchanged. Always rebuild the position from current SLG chain quotes before placing a trade.
