BSM (Black Stone Minerals, L.P.) trades in the Energy sector, specifically Oil & Gas Exploration & Production, with a market capitalization of approximately $2.88B, a trailing P/E of 9.68, a beta of 0.05 versus the broader market, a 52-week range of 11.78-15.49, average daily share volume of 460K, a public-listing history dating back to 2015, approximately 115 full-time employees. These structural characteristics shape how BSM stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.05 indicates BSM has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. The trailing P/E of 9.68 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. BSM pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a long put on BSM?
A long put buys downside exposure with a fixed maximum loss equal to the premium paid; profit accrues if the underlying closes below the strike minus premium at expiration.
Current BSM snapshot
As of May 15, 2026, spot at $13.99, ATM IV 28.90%, IV rank 5.37%, expected move 8.29%. The long put on BSM 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 long put structure on BSM specifically: BSM IV at 28.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a BSM long put, with a market-implied 1-standard-deviation move of approximately 8.29% (roughly $1.16 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 BSM expiries trade a higher absolute premium for lower per-day decay. Position sizing on BSM should anchor to the underlying notional of $13.99 per share and to the trader's directional view on BSM stock.
BSM long put setup
The BSM long put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With BSM near $13.99, the first option leg uses a $13.99 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BSM 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 BSM shares for the stock leg in covered calls and collars).

BSM thesis for this long put
The market-implied 1-standard-deviation range for BSM extends from approximately $12.83 on the downside to $15.15 on the upside. A BSM long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long BSM position with one put per 100 shares held. Current BSM IV rank near 5.37% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on BSM at 28.90%. As a Energy name, BSM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BSM-specific events.
BSM long put positions are structurally 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. BSM positions also carry Energy sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BSM alongside the broader basket even when BSM-specific fundamentals are unchanged. Long-premium structures like a long put on BSM 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 BSM chain quotes before placing a trade.
