One of the more reliable trading models in the past couple of years has flashed a buy signal. I have been watching the VIX/VXV ratio, as pioneered by Bill Luby, for some time. This investor sentiment indicator measures the term structure of the VIX Index. By my measure, when the ratio falls below 0.92, it has provided reasonably good long entry points in the past (see my previous post Waiting for a Santa Claus rally where I backtested this indicator).
The chart below shows the SPX in the top panel and the VIX/VXV in the bottom panel. The red dotted vertical are previous buy signals when the 3-day moving average of the VIX/VXV fell below the 0.92 mark.
As the NASDAQ 100 stages an upside breakout to new highs, the VIX/VXV is a confirmation of the underlying strength of the stock market.
If the past is any guide, this is a tradable rally that is likely to take the major averages higher, notwithstanding the worries about the Fed taper, the new Fed chair, the debt ceiling debate, etc.

Thanks for the mention, Cam. Like all indicators, VIX:VXV has periods when it performs very well and other periods when it is more likely to lead you astray, but on balance, I think this one is worth watching.
Cheers,

Bill - I agree that you shouldn't depend on any single indicator. However, given the kind of strength that I am seeing from my other indicators, this is a meaningful confirmation of my bullish outlook.
Very good post, and thank you for introducing this valuable metric to me.
I looked at it since 2009. As a standalone metric (which you rightly do not advocate), it has been more accurate in the past 2 years (2012-13) than in the 3 years before that (2009-11). Chart here: http://scharts.co/1eB59s1
I will use this in the future.
Many thanks,
