VIX: Could somebody explain this discrepancy?

Enclosed please find pics for the VIX Index and the front month contract charts.

They look so different.

My system has signaled a possible long on this instrument (the index), but after looking at the charts of the delivery months....it's just crazy.

I have not seen this type of discrepancy in other instruments.

Could somebody elaborate ?

Thanks a million !!!

There is a large contango on the back/front months and cash. Volatility futures mimic option vega -- the term structure of volatility futures carry +convexity as do the back month options in terms of vegas.

The futures rapidly converge to cash as expiration approaches, hence the divergence seen on the charts.
 
Thanks riskarb ! Always appreciate your generosity.

I had understood the convergence that happens between cash and front months, but I had never seen something so out of proportion.

Is this something that only happens with the VIX ?

The cash chart is showing an uptrend, but the front month just broke through support in a clear downtrend.

If the front month is a good short, but the cash is not even close to confirming taking such a position, following the front wouldn't make sense, correct?

Thank you very much again.

The futures have traded under cash which is predictive of a continued drop in VIX in the next session or two. Any sustained backwardation would only be seen in scenarios with a high cash VIX value, say above 20 or so. I wouldn't follow the futures chart unless you're intent on trading arbitrage. There is no "clean" method of isolating the strip-vol, thus no spread-trade will result. Don't look to buy the backwardation unless you're bullish on vol, directionally.

I would ignore the futures and base your analysis on the cash index.
 
Will do.

Thanks !!!
