I've always maintained that IV should be looked at relatively. Which is best;
a) An 8% annual return on capital, when inflation is running at 10%
or
b) A 5% annual return on capital, when inflation is running at 3%
Similarly, which is best;
a) IV running at 9%, when HV runs at 7%
or
b) IV running at 20%, when HV runs at 22%
Having said that, the argument that IV is likely to increase from these levels is a good one. It's that what makes me cautious in writing and occasionally joining the mug punter in buying options.
