In the book "The Concepts and Practice of Mathematical Finance" author M. Joshi writes on page 12 the following:
"From the point of view of risk, we can regard an option as an attempt to encapsulate a specific piece of risk. As the option is purer in its risk, its value is more sensitive to market changes, and therefore the amounts to be gained and lost on options are much larger. However, it would be a mistake to view an option as a risky asset which only the foolhardy would buy. The purpose of an option is to allow the buyer to guard against certain events and thus reduce his risk. The best metaphor for an option is to regard it as concentrated acid---handled carefully a very important tool, but used carelessly very dangerous." [My italics]
I am not sure as to what the author precisely means by the sentence "As the option is purer in its risk (...)". What is meant by 'purer' here? I find it to be very cryptic, and I just cannot make sense of it. As a result, I'm also unsure if I understand the other points he makes here.
So my question is simply: What exactly is meant here (specifically about the option being "purer" in its risk)?
