Description


The Financial Modeling package is a collection of tools for mathematical finance. This package builds on the functionality available in other packages such as LinearAlgebra, Statistics, Optimization, and CurveFitting. The package supports a wide range of common tasks such as date arithmetic, cash flow analysis, option pricing, term structure analysis, and simulation.
For an introduction to the Finance package, see the Finance Tour.

Cash Flow Analysis


The Financial Modeling package provides a number of tools for constructing cash flows and for performing basic sensitivity analysis.
More information and detailed examples can be found in Finance/Overview/CashFlowAnalysis.

Financial Instruments


The Financial Modeling package provides tools for constructing various financial instruments such as Europeanstyle and Americanstyle options with any payoff function, bonds, as well as some interest rate instruments. In addition to this, the package provides tools for valuing these instruments and computing their market sensitivities (the Greeks). The following instruments are supported.

Stochastic Processes


The Financial Modeling package supports a wide range of stochastic processes used in Financial Engineering. This includes processes for modeling equity prices, meanreverting processes, pure jump processes, jump diffusions as well as multivariate Ito processes. In addition, the package provides tools for building more complicated processes from simple ones. Below is the list of supported processes:
