How SMHI iv/hv history Data Feeds Strategy Selection

Strategy selection on SEACOR Marine Holdings Inc. options does not derive from any single metric in isolation. The iv/hv history view above sits inside a broader read: ATM IV currently sits at 69.3% and dealer gamma exposure is negative, so dealer hedging amplifies directional moves. Combine the iv/hv history data here with the volatility-skew surface, dealer-gamma exposure, max-pain level, and upcoming-events calendar to build a positioning thesis. Risk-defined structures (credit spreads, debit spreads, iron condors) are usually safer than naked positions while the regime is uncertain; the data on this page anchors the inputs but does not by itself constitute a trade thesis.

How to read the SMHI IV vs HV chart

The dual-line chart above tracks ATM implied volatility (forward-looking, what the chain is pricing) against 20-day realized historical volatility (backward-looking, what actually happened). ATM IV currently prints at 69.3%, 9.6% IV rank, against 74.6% realized over the trailing 20 trading days. Implied is currently below realized by 5.3 vol points, an inverted regime where premium buyers are underpaying for the move - rare and often a setup for IV expansion. Persistent IV-above-HV is the variance-risk-premium-positive state typical of equity markets; persistent IV-below-HV is rare and usually marks underpriced vol that often expands.

SMHI IV/HV regimes and trade selection

SMHI sits in the bottom quartile of its 1-year IV range. Low-IV-rank regimes favor premium-buying or long-vol structures - long calls/puts, debit spreads, calendar spreads, long straddles. The risk: low rank can persist for months while theta decay eats premium-buyers alive without a vol-expansion catalyst.

Using SMHI vol history alongside the term structure

The IV/HV gap on this page captures the level of premium; the term-structure slope on the volatility page captures its shape across expirations. Term structure is roughly flat at -0.007, no strong near vs far premium being priced. Pair the rank read with the slope read with the event calendar to choose the right tenor for the structure.

SMHI IV/HV signal in volatility-cycle context

Equity-vol cycles tend to compress and expand on multi-month timeframes: a typical sequence runs low-IV-rank consolidation (months of flat tape, decaying premium) into a vol-expansion catalyst (earnings miss, macro shock, regime change) into elevated-IV-rank stress (premiums fat, dispersion high) back to mean-reverting compression. SMHI's current 9.6% IV rank places the ticker in the compression phase of that cycle. Compression phases are profitable for theta-harvesting structures but tend to end with abrupt vol-expansion regimes that hit short-vol books fast. The ratio of HV-20 (74.6%) to HV-60 (69.4%) gives a second cycle indicator: when 20-day exceeds 60-day, recent realization is running hotter than the trailing-quarter average - typically a sign that recent days have already started expanding vol regardless of where IV rank prints. Use the time series above to spot inflection points: meaningful IV/HV gap closures and openings tend to precede regime shifts by a few sessions.

Frequently asked SMHI iv/hv history questions

Is SMHI options pricing rich or cheap right now?
As of Aug 14, 2026, SEACOR Marine Holdings Inc. (SMHI) ATM IV is 69.3% against 20-day realized volatility of 74.6%. IV rank is 9.6%. Realized volatility currently exceeds implied: an inversion of the typical equity volatility risk premium that often precedes IV expansion.
What is the SMHI variance risk premium?
The variance risk premium is the persistent gap between implied and subsequently realized volatility. In equity markets it averages positive because option sellers demand compensation for bearing variance shocks. SMHI is currently pricing inverted to the historical pattern, which is one input to whether short-vol or long-vol structures carry their typical edge.
What does SMHI IV rank mean for strategy selection?
IV rank normalizes the current ATM IV to its 1-year range: 0% is the low, 100% is the high. SMHI's current rank of 9.6% signals where current pricing sits in its own 1-year history. High-rank regimes typically favor premium-selling structures (credit spreads, condors, covered calls); low-rank regimes typically favor premium-buying or long-volatility structures.
