AGEN (Agenus Inc.) trades in the Healthcare sector, specifically Biotechnology, with a market capitalization of approximately $144.1M, a trailing P/E of 2.04, a beta of 1.61 versus the broader market, a 52-week range of 2.71-7.34, average daily share volume of 787K, a public-listing history dating back to 2000, approximately 316 full-time employees. These structural characteristics shape how AGEN stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 1.61 indicates AGEN has historically moved more than the broader market, amplifying both the directional payoff and the realized volatility relative to an index-equivalent position. The trailing P/E of 2.04 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 AGEN?
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 AGEN snapshot
As of May 15, 2026, spot at $3.58, ATM IV 112.20%, IV rank 38.41%, expected move 32.17%. The collar on AGEN 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 AGEN specifically: IV regime affects collar pricing on both sides; mid-range AGEN IV at 112.20% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 32.17% (roughly $1.15 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 AGEN expiries trade a higher absolute premium for lower per-day decay. Position sizing on AGEN should anchor to the underlying notional of $3.58 per share and to the trader's directional view on AGEN stock.
AGEN collar setup
The AGEN 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 AGEN near $3.58, the first option leg uses a $3.76 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed AGEN 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 AGEN shares for the stock leg in covered calls and collars).

|---|---|---|---|

| Buy 1 | Put | $3.40 | N/A |

AGEN thesis for this collar
The market-implied 1-standard-deviation range for AGEN extends from approximately $2.43 on the downside to $4.73 on the upside. A AGEN collar hedges an existing long AGEN 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 AGEN IV rank near 38.41% is mid-range against its 1-year distribution, so the IV signal is neutral; the collar thesis on AGEN should anchor more to the directional view and the expected-move geometry. As a Healthcare name, AGEN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to AGEN-specific events.
AGEN 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. AGEN positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move AGEN alongside the broader basket even when AGEN-specific fundamentals are unchanged. Always rebuild the position from current AGEN chain quotes before placing a trade.
