What is the current INMB ATM implied volatility?

As of Jun 30, 2026, INmune Bio, Inc. (INMB) at-the-money implied volatility is 21.9%. IV rank is 0.1% on a 0-100% scale anchored to the 1-year IV range. ATM IV is the volatility input that makes a Black-Scholes-equivalent model reproduce the listed at-the-money option prices.

Is INMB IV high or low historically?

IV is subdued relative to its 1-year history, conditions that typically favor premium-buying strategies (long calls, long puts, debit spreads, calendar spreads).

What does INMB volatility skew tell options traders?

Volatility skew is the pattern by which IV varies across strikes for a given expiration. INmune Bio, Inc. shows upside-skewed pricing: 25-delta calls trade richer than 25-delta puts, often reflecting upside speculation or squeeze risk. Skew matters for risk-defined strategy selection: when downside puts are rich, put-credit spreads capture more premium; when upside calls are rich, call-credit spreads or covered-call writes harvest more.

As of Jun 30, 2026, INmune Bio, Inc. (INMB) at-the-money implied volatility is 21.9%. IV rank is 0.1% (where 0% is the 52-week low and 100% is the 52-week high). IV percentile is 0.8%. The 25-delta skew is +0.089: calls carry premium over puts, indicating upside speculation or squeeze risk. High IV rank typically favors premium-selling strategies; low IV rank favors premium-buying.

INMB Strategy Selection at Current Volatility Levels

For INmune Bio, Inc. options at 21.9% ATM IV, low IV rank (0.1%) favors premium-buying or long-vol structures: long calls or puts, debit spreads, calendar spreads, long straddles. The risk: low-rank regimes can persist for months while time decay eats premium-buyers alive. The 25-delta skew tilts to calls, so call-credit spreads or covered-call writes harvest more premium than put-credit spreads of the same width. Pair the vol-rank read with the dealer-gamma view and the upcoming-events calendar to confirm the strategy fits both the structural regime and the path-dependent risk. The variance risk premium - the persistent gap between implied and subsequently realized vol - is positive in equity markets on average; high IV rank typically reflects a stretch where the premium is wider than usual.

How to read the INMB volatility surface

ATM IV currently prints at 21.9%, 0.1% IV rank, against 85.2% realized over the trailing 20 trading days. Implied is currently below realized by 63.3 vol points, an inverted regime where premium buyers are underpaying for the move - rare and often a setup for IV expansion. The 25-delta skew tilts to calls at 0.089, meaning out-of-the-money calls are bid up relative to equivalent-delta puts - often a sign of bullish positioning or upcoming catalyst. The term-structure slope of 1.019 is in contango - longer-dated IV trades above near-dated IV, the typical resting state when no immediate catalysts are pricing in.

INMB IV rank and the variance risk premium

INMB sits in the bottom quartile of its 1-year IV range (rank 0.1%). Low-IV-rank regimes favor premium-buying or long-vol structures - long calls/puts, debit spreads, calendar spreads, long straddles. The risk: low-rank regimes can persist for months, and time decay eats premium-buyers alive without a vol expansion or directional move to compensate. Compared with 60-day realized HV of 74.7%, current ATM IV is 52.8 vol points cheap.

Trading vol on INMB: practical notes

The variance risk premium - the persistent gap between implied and subsequently realized volatility - is positive on equity-market averages, which is why premium-selling carries a long-run edge. But the edge is averaged across a distribution; individual realizations can blow past the implied move in either direction. INMB front-month expiration sits at 17 days; near-dated structures get the highest theta decay but also the largest gamma sensitivity, so the same vol-rank read translates into very different structures at 7 DTE vs 45 DTE. Pair the rank read with the dealer-gamma view, the term-structure shape, and the upcoming-event calendar to confirm the trade fits both the structural regime and the path-dependent risk. Risk-defined structures (credit/debit spreads, condors, butterflies) are usually safer than naked positions when the regime is uncertain.

INMB volatility surface: linking strikes to tenors

The skew-by-strike chart higher up and the term-structure-by-DTE chart together describe the INMB implied-volatility surface - the two-dimensional grid of IV across strike and expiration that determines every option premium on the chain. Currently the 25-delta skew is 0.089 and the term-structure slope is 1.019, a combination that is unusual: call-skewed and contango together typically indicate bullish positioning into a multi-month catalyst. Term structure tells you when the market expects the action; skew tells you which direction. Combined with the 0.1% IV rank, the surface gives a complete read on whether INMB options are cheap, fair, or expensive across both dimensions. Practitioners watch surface dynamics (skew steepening, term-structure inversion) alongside level (IV rank) - level moves are common but surface shape changes typically signal regime-level shifts in how the chain is being positioned.

For INMB specifically, the surface read fits into a broader options-trading toolkit. Single-leg directional positions (long calls or puts) depend almost entirely on level: cheap IV at any skew/term shape favors buyers, rich IV favors sellers. Risk-defined spreads (vertical credit/debit spreads, iron condors, butterflies) depend on both level and skew: put-skewed surfaces make put-side credit spreads collect more premium per width than call-side, and the asymmetry can compound or offset the directional thesis. Calendar and diagonal spreads depend on term shape: contango makes long-back-month / short-front-month structures cheaper to put on but harder to harvest theta from quickly. Pair the surface read with the dealer-gamma view, the upcoming-event calendar, and the underlying-trend context to choose the strike, the tenor, and the structure family that match both the regime and the conviction level.
