We're sorry, but at this time we do not have very much research on the VIX.
VIX Futures history goes back to 2004, not really enough history for seasonal trading strategies, but we are taking it into consideration for the future.However, we do have a free long term monthly VIX chart here: http://www.mrci.com/pdf/vix.pdf
Please note: this is a chart of the Cash market, not futures, going back to 1986.
Our subscriber website, MRCI Online also features seasonal pattern charts for the VIX identified as CBOE Volatility Index and direct links to historical daily charts as far back as 1986.http://www.mrci.com/
