Abstract

A system, method, software, and portfolios for managing risk in markets relating to a commodity delivered over a network are described, in which a market participant constructs portfolios of preferably liquid price risk instruments in proportions that eliminate the Spatial Price Risk for the market participant'"'"'s underlying position. Techniques are also disclosed for constructing and evaluating new price risk instruments and other sets of positions, as well as identifying arbitrage opportunities in those markets.

Claims

1. A method for evaluating a portfolio of price risk instruments in a market related to a commodity delivered over a network, comprising the steps of:

a computer estimating a plurality of distribution factors indicating effects on one or more congestible lines in the network due to transfers of the commodity at respective locations in the network; and

a computer evaluating the portfolio based on the estimated distribution factors,

wherein the step of evaluating the portfolio includes a step of calculating a cost f based on the formula f=(z′

+y′

F, wherein;

y represents the portfolio of price risk instruments;

z represents underlying positions in the market at the prospective time;

P represents a market of available price risk instruments;

F represents prices for the available price risk instruments;

A represents the distribution factors;

λ

represents prices of congestion for the congestible lines; and

′

(prime) denotes a transpose of a matrix.

2. A computer-readable medium bearing instructions for evaluating a portfolio of price risk instruments in a market related to a commodity delivered over a network, said instructions being arranged to cause one or more processors upon execution thereby to perform the steps of:

estimating a plurality of distribution factors indicating effects on one or more congestible lines in the network due to transfers of the commodity at respective locations in the network; and

evaluating the portfolio based on the estimated distribution factors,

wherein the step of evaluating the portfolio includes a step of calculating a cost f based on the formula f=(z′
