What is a long put on IFRX?
A long put buys downside exposure with a fixed maximum loss equal to the premium paid; profit accrues if the underlying closes below the strike minus premium at expiration.
Current IFRX snapshot
As of May 15, 2026, spot at $2.29, ATM IV 206.40%, IV rank 39.45%, expected move 59.17%. The long put on IFRX 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 IFRX specifically: IFRX IV at 206.40% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 59.17% (roughly $1.36 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 IFRX expiries trade a higher absolute premium for lower per-day decay. Position sizing on IFRX should anchor to the underlying notional of $2.29 per share and to the trader's directional view on IFRX stock.
IFRX long put setup
The IFRX 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 IFRX near $2.29, the first option leg uses a $2.29 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed IFRX 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 IFRX shares for the stock leg in covered calls and collars).

IFRX thesis for this long put
The market-implied 1-standard-deviation range for IFRX extends from approximately $0.93 on the downside to $3.65 on the upside. A IFRX long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long IFRX position with one put per 100 shares held. Current IFRX IV rank near 39.45% is mid-range against its 1-year distribution, so the IV signal is neutral; the long put thesis on IFRX should anchor more to the directional view and the expected-move geometry. As a Healthcare name, IFRX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to IFRX-specific events.
IFRX 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. IFRX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move IFRX alongside the broader basket even when IFRX-specific fundamentals are unchanged. Long-premium structures like a long put on IFRX 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 IFRX chain quotes before placing a trade.
Frequently asked questions
- What is a long put on IFRX?

- How are IFRX long put max profit and max loss calculated?
