SPIKES Volatility Index

The SPIKES Volatility Index (index symbol: SPIKE), is a measure of the expected 30-day volatility in the SPDR S&P 500 ETF (SPY). SPY is the largest exchange traded fund in the world and tracks the most watched stock index in the United States. SPIKES is built using the popular variance swap methodology and uses live SPY option prices to calculate volatility.  This is consistent with the way the trading community is used to modelling risk and hedging exposure.
