IFRX Bear Put Spread Strategy
IFRX (InflaRx N.V.), in the Healthcare sector, (Biotechnology industry), listed on NASDAQ.
InflaRx N.V. is a clinical-stage biopharmaceutical firm dedicated to discovering and developing novel inhibitors leveraging C5a technology, primarily operating in Germany and the United States. The company's focus on C5a stems from its critical role as an inflammatory mediator implicated in the progression of various autoimmune and inflammatory diseases. Its primary product candidate, vilobelimab, is an innovative, first-in-class anti-C5a monoclonal antibody delivered intravenously. Vilobelimab has progressed through several clinical stages for multiple indications: It has successfully completed a Phase III clinical trial for hidradenitis suppurativa (HS), a rare, chronic, and debilitating systemic inflammatory skin condition. It is currently undergoing Phase II trials for anti-neutrophil cytoplasm antibody associated vasculitis (AAV), a rare and life-threatening autoimmune disorder, and for PD-1/PD-L1 inhibitor resistant/refractory locally advanced or metastatic cutaneous squamous cell carcinoma (CSCC). An exploratory Phase IIa study is also underway for pyoderma gangraenosum (PG), a chronic inflammatory skin disorder.

What is a bear put spread on IFRX?
A bear put spread buys an at-the-money put and sells an out-of-the-money put at a lower strike for defined risk and defined reward bounded by the strike width.
IFRX snapshot
As of August 14, 2026, spot at $2.01, ATM IV 42.10%, IV rank 5.33%, expected move 12.07%. The bear put spread on IFRX below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.
Why this bear put spread structure on IFRX specifically: IFRX IV at 42.10% is on the cheap side of its 1-year range, which favors premium-buying structures like a IFRX bear put spread, with a market-implied 1-standard-deviation move of approximately 12.07% (roughly $0.24 on the underlying). The 35-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 $2.01 per share and to the trader's directional view on IFRX stock.
IFRX bear put spread setup
The IFRX bear put spread 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 at $2.01 on that close, the first option leg uses a $2.01 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 35-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).
| Action | Type | Strike / Basis | Premium (est) |

IFRX thesis for this bear put spread
The market-implied 1-standard-deviation range for IFRX extends from approximately $1.77 on the downside to $2.25 on the upside. A IFRX bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on IFRX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current IFRX IV rank near 5.33% 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 IFRX at 42.10%. 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 bear put spread positions are structurally moderately 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 bear put spread 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.
