How CBRS iv/hv history Data Feeds Strategy Selection
Strategy selection on Cerebras Systems 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 80.7% 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 CBRS IV vs HV chart
The dual-line chart below 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 80.7%, against 71.5% realized over the trailing 20 trading days. Implied is pricing above realized by 9.2 vol points, the typical variance-risk-premium positive state in which premium sellers earn the gap. 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.
CBRS IV/HV regimes and trade selection
Using CBRS 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. Backwardation (negative slope -0.026) indicates acute near-term event risk - near-dated tenors price disproportionate vol. Pair the rank read with the slope read with the event calendar to choose the right tenor for the structure.
CBRS 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. The ratio of HV-20 (71.5%) to HV-60 (101.7%) 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 below to spot inflection points: meaningful IV/HV gap closures and openings tend to precede regime shifts by a few sessions.

- As of Oct 14, 2026, Cerebras Systems Inc. (CBRS) ATM IV is 80.7% against 20-day realized volatility of 71.5%. CBRS options are pricing in more volatility than the stock has recently realized: a positive variance risk premium worth 9.2 vol points.
- What is the CBRS 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. CBRS is currently priced consistently with this premium, which is one input to whether short-vol or long-vol structures carry their typical edge.
- What does CBRS 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. CBRS's current rank 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.
