When Does Extra Risk Strictly Increase an Option's Value?

Abstract

It is well known that risk increases the value of options. This article makes that precise in a new way. The conventional theorem says that the value of an option does not fall if the underlying asset becomes riskier in the conventional sense of the mean-preserving spread. This article uses two new definitions of 'riskier' to show that the value of an option strictly increases (i) if the underlying asset becomes 'pointwise riskier,' and (ii) only if the underlying asset becomes 'extremum riskier.' , Oxford University Press.
