The VIX tells you how much movement the options market expects. It does not tell you which direction traders are afraid of, or whether the people buying protection are frightened or simply hedged. Two other measures do, and they disagree with the VIX often enough to be worth watching.

Short answer: two different measures of the same fear
Short answer: The put/call ratio measures how many puts trade relative to calls — a volume-based sentiment gauge. Skew measures the price difference between out-of-the-money puts and out-of-the-money calls — a pricing-based gauge of what downside protection costs. One counts contracts, the other prices them, and they can point in opposite directions.
Equity-only vs total put/call
This distinction matters more than most commentary acknowledges.
The equity-only ratio covers options on individual stocks, where activity skews toward retail and directional speculation. It is the more common sentiment reading and the more contrarian one — extreme readings have historically clustered near turning points.
The total ratio includes index options, which are dominated by institutional hedging. A pension fund buying index puts to protect a portfolio it intends to hold is not expressing a bearish view; it is buying insurance. Reading heavy index put volume as bearish sentiment mistakes risk management for a forecast.
Because index volume is large, the total ratio is structurally higher than the equity-only ratio, and comparing a reading against the wrong historical series produces nonsense. Check which one a chart is showing before drawing any conclusion from it.
25-delta skew: the price of crash protection
Skew compares the implied volatility of an out-of-the-money put to that of an out-of-the-money call at equivalent distance from spot — conventionally 25-delta on each side.
In equity markets puts are almost always more expensive than equivalent calls. This is persistent and structural: investors are typically long equities and want downside protection, while index declines tend to be faster and more correlated than rallies. Steepening skew means downside protection is getting relatively more expensive; flattening skew means it is getting cheaper, which can indicate complacency or simply that hedgers have already bought what they need.
When high put volume is hedging, not bearishness
The single most common misreading of options data. Several patterns produce elevated put volume with no bearish content at all.
- Systematic hedging programmes. Funds that roll protection on a schedule generate large, calendar-driven put volume independent of any view.
- Collar structures. Buying a put financed by selling a call. Shows as put buying while being a neutral-to-mildly-bullish position for a holder of the underlying.
- Put selling. Volume data records contracts traded, not who initiated. Heavy put volume can be investors selling puts to collect premium — an outright bullish stance that looks identical in the ratio.
- Expiry mechanics. Volume clusters around large expiries for reasons that are structural rather than informational.
This is why skew is a useful cross-check. Volume tells you how many contracts changed hands; skew tells you what the market was willing to pay. Rising put volume with flat skew suggests supply meeting demand — not panic.
Combining skew, VVIX, and term structure
Three complementary readings give a fuller picture than any one alone. VVIX — the volatility of the VIX — indicates whether the market is paying up for protection against a volatility spike itself, and it frequently leads the VIX at inflection points. VIX term structure shows whether near-dated volatility is priced above or below longer-dated; inversion signals acute near-term stress, and its resolution has historically been more informative than the level.
The configuration worth noticing is disagreement: a low VIX with steep skew and elevated VVIX describes a market that appears calm on the surface while paying up for tail protection underneath. That combination carries more information than any single number and appears in none of the headline readings.
Contrarian readings and the levels that mattered
The contrarian case is that extreme readings mark exhaustion — everyone who wanted protection has bought it, leaving positioning one-sided and vulnerable to reversal. Historically, extreme equity-only put/call readings have clustered near meaningful lows.
The caveats are substantial. Thresholds that “worked” were identified retrospectively and have drifted as market structure changed. The growth of same-day options has altered volume composition in ways that make historical comparisons unreliable. And extremes can persist or deepen — an indicator at a record does not preclude a new record.
What this article does not conclude
These are positioning and pricing measures, not forecasts. They describe what the options market has done and what it currently charges, which is information about the present rather than the future.
Put/call ratios are published daily by Cboe, and skew data is available from most options analytics providers. Definitions vary between providers — particularly on what counts as 25-delta — so figures are not directly comparable across sources.
