A counterexample concerning the variance-optimal martingale measure
The present note addresses an open question concerning a sufficient characterization of the variance-optimal martingale measure. Denote by S the discounted price process of an asset and suppose that Q? is an equivalent martingale measure whose density is a multiple of 1− φ • ST for some S-integrable process φ. We show that Q? does not necessarily coincide with the variance-optimal martingale me...
متن کاملThe Variance{optimal Martingale Measure for Continuous Processes
We prove that for continuous stochastic processes S based on ( ;F;P) for which there is an equivalent martingale measureQ with square-integrable density dQ=dPwe have that the so-called "variance optimal" martingale measure Q for which the density dQ=dPhas minimal L(P)-norm is automatically equivalent to P. The result is then applied to an approximation problem arising in Mathematical Finance.
متن کاملComputational Finance – The Martingale Measure and Pricing of Derivatives
At t = 0, two instruments are available. Any amount (even fractional) of either instrument may be sold or puschased at the specified market price i.e., arbitrary short or long positions are allowed. A risk free asset or bond, B, and a stock, S. At t = 0 (the first period), the bond is worth B(0), and, the stock is worth S(0) = 100. At t = T (the second period), the economy can be in one of two ...
متن کاملDERIVATIVES PRICING VIA p-OPTIMAL MARTINGALE MEASURES: SOME EXTREME CASES
In an incomplete financial market in which the dynamics of the asset prices is driven by a d-dimensional continuous semimartingale X, we consider the problem of pricing European contingent claims embedded in a power utility framework. This problem reduces to identifying the p-optimal martingale measure, which can be given in terms of the solution to a semimartingale backward equation. We use th...
متن کاملSaddlepoint approximation methods for pricing derivatives on discrete realized variance
We consider the saddlepoint approximation methods for pricing derivatives whose payoffs depend on the discrete realized variance of the underlying price process of a risky asset. Most of the earlier pricing models of variance products and volatility derivatives use the quadratic variation approximation as the continuous limit of the discrete realized variance. However, the corresponding discret...
