Options Skew Radar

How expensively the market prices protection — 25Δ put IV vs. 25Δ call IV per ticker, plus a Vol Quadrant showing IV Rank and Risk-Reversal Rank relative to each ticker’s own history. CBOE SKEW/VIX/VVIX free, daily.

Important: Backward-looking options context from 25Δ IV and the CBOE vol indices. The strategy fields in the quadrant are pure structural examples of how expensive or cheap vol is typically traded. Not a buy/sell signal, not investment advice.
Vol Trigger (zero-gamma flip) — the spot level where dealer gamma flips from positive to negative · above trigger = long gamma (dealers dampen vol), below = short gamma (dealers amplify moves)

Market context: CBOE SKEW & VIX

The CBOE SKEW Index measures how expensively the broad market prices tail risk in OTM S&P puts (higher = more crash hedging), the VIX the expected 30-day move.

Frequently Asked Questions

What is options skew?

Skew measures how differently the market prices puts and calls. We compare the implied volatility (IV) of a 25-delta put with that of a 25-delta call (each around 30 days to expiry). If put IV is higher, investors pay a premium for downside protection (put skew, typical for equity indices). If call IV is higher, upside speculation is priced more expensively (call skew, common in single stocks during rallies).

What does the Vol Quadrant show?

The Vol Quadrant places each ticker in two dimensions, each as a percentile rank relative to its own history: the Y axis is IV Rank (how expensive is volatility right now versus its own past) and the X axis is Risk-Reversal Rank (how strongly are calls priced relative to puts). The crosshair at 50 percent splits the plane into four fields, each mapped to a typical options structure: the top is expensive vol (sell premium), the bottom is cheap (buy); the side follows the skew.

What is IV Rank?

IV Rank indicates where current implied volatility sits within its own range over a chosen window — 0 percent at the historical low, 100 percent at the high. An IV Rank of 80 percent means options are currently more expensive than on 80 percent of all days in the window. The window can be switched between 3 months, 6 months, 1 year and 2 years; 1 year is the default.

Is skew a trading signal?

No. This page shows backward-looking options context, not a forecast and not investment advice. The strategy labels in the quadrants are pure structural examples of how expensive or cheap vol is typically traded — not a recommendation for any specific trade. Options are leveraged instruments with a risk of total loss.
