International Securities Exchange Revamps Its Implied Volatility Charts

The International Securities Exchange (ISE), which publishes a superb implied volatility chart that I have featured on my blog VIX and More on a number of occasions, has recently launched an enhanced version of its IV chart. The new version of this chart, which I have appended below, adds an “ISEE value” to the list of data. I have discussed the ISEE call to put ratio frequently in this space in the past. In this incarnation it is simply a ratio of call volume to put volume for the specified security.

I chose Citigroup (C) as my example security (click on chart to enlarge) because all eyes should be on this bank, which is now trading at a 14 year low after hitting 3.57 Friday morning. If Citigroup crumbles, it will dwarf the chaos created by AIG (AIG) and Lehman Brothers (LEH).
