AM (Antero Midstream Corporation) trades in the Energy sector, specifically Oil & Gas Midstream, with a market capitalization of approximately $10.24B, a trailing P/E of 24.88, a beta of 0.66 versus the broader market, a 52-week range of 16.77-23.835, average daily share volume of 2.8M, a public-listing history dating back to 2017, approximately 616 full-time employees. These structural characteristics shape how AM stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.66 indicates AM has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. AM pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a strangle on AM?
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 AM snapshot
As of May 15, 2026, spot at $21.95, ATM IV 23.70%, IV rank 2.47%, expected move 6.79%. The strangle on AM 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 AM specifically: AM IV at 23.70% is on the cheap side of its 1-year range, which favors premium-buying structures like a AM strangle, with a market-implied 1-standard-deviation move of approximately 6.79% (roughly $1.49 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 AM expiries trade a higher absolute premium for lower per-day decay. Position sizing on AM should anchor to the underlying notional of $21.95 per share and to the trader's directional view on AM stock.
AM strangle setup
The AM 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 AM near $21.95, the first option leg uses a $23.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed AM 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 AM shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $23.00 | $0.28 |
| Buy 1 | Put | $21.00 | $0.25 |
AM strangle risk and reward
- Net Premium / Debit
- -$52.50
- Max Profit (per contract)
- Unbounded
- Max Loss (per contract)
- -$52.50
- Breakeven(s)
- $20.48, $23.53
- Risk / Reward Ratio
- Unbounded
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 AM
Strangles on AM 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 AM chain.
AM thesis for this strangle
The market-implied 1-standard-deviation range for AM extends from approximately $20.46 on the downside to $23.44 on the upside. A AM 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 AM IV rank near 2.47% 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 AM at 23.70%. As a Energy name, AM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to AM-specific events.
AM 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. AM positions also carry Energy sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move AM alongside the broader basket even when AM-specific fundamentals are unchanged. Always rebuild the position from current AM chain quotes before placing a trade.
Frequently asked questions
- What is a strangle on AM?
- A strangle on AM is the strangle strategy applied to AM (stock). The strategy is structurally neutral / high-volatility (long premium, OTM): 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. With AM stock trading near $21.95, the strikes shown on this page are snapped to the nearest listed AM chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are AM strangle max profit and max loss calculated?
- 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. For the AM strangle priced from the end-of-day chain at a 30-day expiry (ATM IV 23.70%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$52.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a AM strangle?
- The breakeven for the AM strangle priced on this page is roughly $20.48 and $23.53 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 AM market-implied 1-standard-deviation expected move is approximately 6.79%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a strangle on AM?
- Strangles on AM 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 AM chain.
- How does current AM implied volatility affect this strangle?
- AM ATM IV is at 23.70% with IV rank near 2.47%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.
