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 strangle on BSM?
A long strangle buys an OTM call and an OTM put at offset strikes, cheaper than a straddle but requiring a larger underlying move to profit since both wings start out-of-the-money.
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 strangle 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 strangle 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 strangle, 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 strangle setup
The BSM strangle 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 $14.69 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).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $14.69 | N/A |
| Buy 1 | Put | $13.29 | N/A |

- Max Profit (per contract)
- Unbounded
- Max Loss (per contract)

- None on modeled curve
- Risk / Reward Ratio
- N/A
Upside max profit is unbounded; downside max profit is bounded at the put strike minus the combined debit (reached at zero). Max loss equals the combined debit times 100 (reached anywhere between the two OTM strikes). Two breakevens at call-strike plus debit and put-strike minus debit.

When traders use strangle on BSM

BSM thesis for this strangle
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 strangle is the OTM cousin of the straddle: lower up-front cost but the underlying has to travel further past either OTM strike before the position turns profitable at expiration. 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 strangle positions are structurally neutral / high-volatility (long premium, OTM); 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. Always rebuild the position from current BSM chain quotes before placing a trade.
Frequently asked questions
- What is a strangle on BSM?
- A strangle on BSM is the strangle strategy applied to BSM (stock).

Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a BSM strangle?
- The breakeven for the BSM strangle priced on this page is no defined breakeven on the modeled curve at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current BSM market-implied 1-standard-deviation expected move is approximately 8.29%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a strangle on BSM?
- Strangles on BSM are the cheaper cousin of the straddle - traders use them when they want a large directional move but are willing to give up the inner-strike sensitivity in exchange for a lower up-front debit on the BSM chain.
