Quote from kubilai:
The article indicates that people tend to over estimate the volatility of the underlying. However, it doesn't take into account the premiums paid for the expiring options, nor the gains made on the exercised options. So it's like a trader claiming he had a 75% win percentage, but you won't know whether he's profitable or not without knowing his profit vs loss ratio.

Quote from torontoman:
Getting back to spreads. What about ratio credit spreads on both sides?
Quote from Babak:
Mavrick,
someone needs to be schooled[/ur]:
"Basically, an options buyer is the gambler and the options seller is the house. When an option is priced, the volatility component is one of, if not the most important part of the equation as it determines the likelihood of a strike price being achieved within a certain amount of time.
Simply put, if the strike price of an option is more than 10% out of the money, and volatility is below 10%, it is very unlikely that the buyer will make money. More importantly, it's unlikely the seller will lose money." http://www.marketwatch.com/news/sto...548-4790-97AC-C28DB3971992}&siteid=mktw&dist=
