چکیده

We consider a financial model with permanent price impact. Continuous time trading dynamics are derived as the limit of discrete rebalancing policies. We then study the problem of super-hedging a European option. Our main result is the derivation of a quasi-linear pricing equation. It holds in the sense of viscosity solutions. When it admits a smooth solution, it provides a perfect hedging strategy.

The Malliavin Derivative and Application to Pricing and Hedging a European Exchange Option

The exchange option was introduced by Margrabe in [1] and its price was explicitly computed therein, albeit with some small variations to the models considered here. After that important introduction of an option to exchange one commodity for another, a lot more work has been devoted to variations of exchange options with attention focusing mainly on pricing but not hedging. In this paper, we d...

Futures for Farmers: Hedging Participation and the Mexican Corn Scheme

Administered commodity price schemes in developing countries have proved ineffective in raising farmers’ incomes and price stabilisation through futures markets is increasingly advocated as the alternative policy objective. A potential difficulty is that farmers tend not to hedge extensively, even in developed countries where access to futures markets is long established. Explanations for this ...

Hedging Through a Limit Order Book with Varying Liquidity

We relax the classical price-taking assumption and study the impact of orders of arbitrary size on price when the availability of liquidity is a concern in hedging. Our paper extends the earlier literature, in that illiquidity is modeled both in terms of depth and resilience. Some of our results hold for more general stochastic processes for the underlying, for example, a generic Lévy process a...

A market-induced mechanism for stock pinning

We propose a model to describe stock pinning on option expiration dates. We argue that if the open interest on a particular contract is unusually large, delta-hedging in aggregate by floor market-makers can impact the stock price and drive it to the strike price of the option. We derive a stochastic differential equation for the stock price which has a singular drift that accounts for the price...

Hedging of Contingent Claims in Incomplete Markets

This report surveys important results in the literature on the problem of hedging contingent claims in incomplete markets. Consider a probability space (Ω,F , P ) and let X be a stochastic process describing the fluctuation of the stock price. Given a contingent claim H, the problem is to find an “optimal” admissible trading strategy, which is a dynamic porfolio of stock and bond (with fixed pr...
