What Is the VIX (Volatility Index)?

Yuka Finance — technical definition and key levels
The VIX (CBOE Volatility Index), nicknamed "the fear index," measures the implied volatility the options market expects for the S&P 500 over the next 30 days, extracted directly from options prices.

What Are the VIX's Key Levels?

What Are VIX Contango and Backwardation?

StructureConditionMeaning
ContangoShort-term VIX < VIX3MNormal state, calm market
BackwardationShort-term VIX > VIX3MImmediate stress signal, acute panic
Concrete example: a VIX moving from 14 in stable contango to 22 with a flip into backwardation in a single session reflects a far more significant regime shift than a standalone VIX spike alone.

On the Yuka Finance cockpit, the VIX, its term structure, and the current volatility regime are displayed live for major indices.

Frequently Asked Questions

Can you trade the VIX directly?

The VIX itself isn't directly tradable, but derivative products (futures, volatility ETFs/ETNs) let you replicate exposure to it.

Does a low VIX mean there's no risk?

No. A persistently low VIX often reflects complacency rather than a genuine absence of risk, and sometimes precedes sharp corrections.

Does the VIX predict a crash?

No, but historically extreme VIX spikes have often coincided with market bottoms, without being a reliable timing signal on their own.
