AMPH (Amphastar Pharmaceuticals, Inc.) trades in the Healthcare sector, specifically Drug Manufacturers - Specialty & Generic, with a market capitalization of approximately $807.8M, a trailing P/E of 10.48, a beta of 0.97 versus the broader market, a 52-week range of 17.03-31.26, average daily share volume of 570K, a public-listing history dating back to 2014, approximately 2K full-time employees. These structural characteristics shape how AMPH stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.97 places AMPH roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 10.48 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price.
What is a collar on AMPH?
A collar pairs long stock with a protective out-of-the-money put financed by a short out-of-the-money call, capping both tails of the position around the current spot.
Current AMPH snapshot
As of May 15, 2026, spot at $16.84, ATM IV 94.50%, IV rank 17.25%, expected move 27.09%. The collar on AMPH 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 collar structure on AMPH specifically: IV regime affects collar pricing on both sides; compressed AMPH IV at 94.50% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 27.09% (roughly $4.56 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 AMPH expiries trade a higher absolute premium for lower per-day decay. Position sizing on AMPH should anchor to the underlying notional of $16.84 per share and to the trader's directional view on AMPH stock.
AMPH collar setup
The AMPH collar below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With AMPH near $16.84, the first option leg uses a $17.68 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed AMPH 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 AMPH shares for the stock leg in covered calls and collars).

AMPH thesis for this collar
The market-implied 1-standard-deviation range for AMPH extends from approximately $12.28 on the downside to $21.40 on the upside. A AMPH collar hedges an existing long AMPH position with a protective put while financing the put cost via a short call; when the premiums roughly offset, the collar acts as a near-zero-cost insurance band around the current spot. Current AMPH IV rank near 17.25% 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 AMPH at 94.50%. As a Healthcare name, AMPH options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to AMPH-specific events.
AMPH collar positions are structurally neutral (protective); 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. AMPH positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move AMPH alongside the broader basket even when AMPH-specific fundamentals are unchanged. Always rebuild the position from current AMPH chain quotes before placing a trade.
