Option Sentiment

Just thought you folks might like to see another piece of artwork related to 
mkt timing.  Some might have been told that option sentiment isn't useful 
anymore for market timing because of hedging purposes.  Perhaps that is 
because they are inputing the wrong data into the ratios.  The belief appears 
to be true for oex volume and open interest.  However, when the CBOE Equity 
call volume is divided by Equity put volume a seemingly useful indicator is 
obtained.  The attached .gif uses the raw unadulterated data from the CBOE 
each day after the close.  The redline in the second subgraph from the top is 
the Equity Call Volume divided by the Equity Put Volume.  The cyan line 
running through it is a ten day exponential moving average of the ratio.  
Note what happens to the OEX as the ratio rises and peaks above about 2.8.  
Also in the 3rd subgraph from the top is a three day summation times a scale 
factor of 10 of the ratio and thus provides a warning when it rises above the 
80 line.   The bottom plot is a 5 day stochastic momentum index with 3 day 
smoothing from Bill Blau's Momentum and Divergence book.  When the SMI and 
C/P ratio have peaked a pretty good Put trade can be made.  The confusing 
situation now is the C/P ratio is way ahead of the SMI.  Will be interesting 
to see how the C/P, OEX and SMI play out over the next few days.
