What VIX measures
VIX derives expected volatility from S&P 500 option prices. It looks roughly thirty days ahead and expresses the result on an annualised scale. A higher reading describes greater expected fluctuation rather than predicting a specific rise or fall.
A reading of 25 does not mean a 25% chance of a market decline. Implied volatility describes the size of expected moves; realised fluctuations can differ. It is not a direct poll of every investor’s opinion.

The index and volatility products
This chart uses ^VIX in index points, not a futures or fund price. The index cannot be bought directly. Volatility-linked products can hold futures, whose results also depend on rolling between maturities.
Daily change is the relative movement of VIX against its previous reference. A rising VIX is not the return earned by an equity holder. The quote timestamp identifies the observation’s age and values can be delayed. We do not assign another instrument’s trading volume to this calculated index.
Using VIX in context
Follow it alongside the S&P 500 and US Dollar Index. Their movements provide context rather than proving causation or establishing the next direction. Unverified VIX calculation hours are not replaced with the regular US equity session.
