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 long put on AM?

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 long put 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 long put 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 long put, 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 long put setup
The AM 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 AM near $21.95, the first option leg uses a $22.00 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).

When traders use long put on AM
Long puts on AM hedge an existing long AM stock position or express a bearish view with defined risk; position sizing typically scales the put notional to the underlying AM exposure being hedged.
AM thesis for this long put
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 put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long AM position with one put per 100 shares held. 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 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. 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. Long-premium structures like a long put on AM 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 AM chain quotes before placing a trade.
