Current BDN snapshot

As of May 15, 2026, spot at $2.99, ATM IV 498.60%, IV rank 100.00%, expected move 142.94%. The bear put spread on BDN 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 bear put spread structure on BDN specifically: BDN IV at 498.60% is rich versus its 1-year range, which makes a premium-buying BDN bear put spread relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 142.94% (roughly $4.27 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 BDN expiries trade a higher absolute premium for lower per-day decay. Position sizing on BDN should anchor to the underlying notional of $2.99 per share and to the trader's directional view on BDN stock.

BDN bear put spread setup

The BDN 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 BDN near $2.99, the first option leg uses a $2.99 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BDN 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 BDN shares for the stock leg in covered calls and collars).

BDN thesis for this bear put spread

The market-implied 1-standard-deviation range for BDN extends from approximately $-1.28 on the downside to $7.26 on the upside. A BDN bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on BDN, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current BDN IV rank near 100.00% sits in the upper third of its 1-year distribution, which historically reverts; this raises the bar for premium-buying structures and lowers it for premium-selling structures on BDN at 498.60%. As a Real Estate name, BDN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BDN-specific events.

BDN 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. BDN positions also carry Real Estate sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BDN alongside the broader basket even when BDN-specific fundamentals are unchanged. Long-premium structures like a bear put spread on BDN 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 BDN chain quotes before placing a trade.
