Abstract
Geometric Average-Rate Options An Exact Closed-End Evaluation Formula
This contribution seeks to evaluate geometric average-rate options. It develops a closed-end evaluation formula, easy to programme, which differs significantly from the formula published by Kemna and Vorst in 1990. It turns out, among other things, that the variance of the geometric average rate is a quadratic function of the residual lifetime of the option, when a constant rate of variance is assumed for the rate of the underlyings. If the period at the base of the geometric average is reduced to one day, the resultant special cases represent the classic formulae for European options.
