IMPLIED VOLATILITY

Editor,

I enjoyed Sam Bhugaloo’s recent article in STOCKS & COMMODITIES (“The Power Of Implied Volatility,” July 2006); the beer froth analogy really helped explain exactly what is going on. I have some questions:

1. Some charts use two years of implied volatility data and others used six months. Doesn’t that have an impact on the percentage increase or decrease? How do you know which time to use?

2. What sources offer the information you used in the article so I can begin to track some of the implied volatility? I see that you’ve used Optionetics; are there others?

Thanks for your email. I have had much positive feedback since the article was published and I am currently working on another that I hope will be published also in due course...
