Equity Put-Call Ratio Plummets by Pater Tenebrarum
If This Is not a Data Glitch, it Is Remarkable
We regularly go through a number of market data, and yesterday something caught our eye.
The CBOE equity put-call volume ratio appears to have plunged to one of its lowest one day readings in history.
Unless this is a data glitch (we don't want to rule the possibility out just yet), this is a quite noteworthy development, especially as it happened concurrently with a rather weak market bounce, against a dubious technical backdrop.

A longer term weekly chart shows that such a low reading has definitely not been seen in the recent past:

Even the very enthusiastic early 2011 low in the ratio was higher than yesterday's – click to enlarge.

The caveat is that such extremely skewed readings can sometimes be the result of a single very large trade and we don't know at this point whether one of those has taken place. We usually try not to over-analyze such data though – it is what it is.
In order to see whether corroboration from related indicators was available, we also took a look at the ISE sentiment index, which measures a call-put ratio of newly opened positions (i.e., exclusively 'buy to open' positions) on the ISE options exchange. Contrary to the normally employed put-call ratio, very high numbers show excessive optimism and conversely, very low index numbers indicate excessive pessimism. The advantage of the ISE index is that large institutional option writers are not skewing its readings.
The ISE sentiment index seems to confirm that short term optimism about the stock market has spiked among option traders. Here is the chart – the current one day reading is among the highest recorded in recent years. The ten day average is still below previous extreme values, which is no doubt a result of recent market weakness. What is noteworthy is the swiftness with which opinion has changed. That is normally not a good sign in the context of a weak looking market.

Conclusion:
As noted above, unless these readings are not the result of a data glitch, they are noteworthy. There is still the possibility of an outlier trade skewing the data, but this seems actually less likely in view of the ISE index reading. If the data can be taken at face value, they represent a
negative signal for the stock market. http://www.acting-man.com/?p=25632
