Aims
- To provide an introduction to the mathematical theory of financial products.
- Provide advanced knowledge and critical understanding of pricing of financial products and derivatives.
Content
- Introduction to options and markets: the probabilistic basis for valuation of financial products. Arbitrage.
- Background in basic probability theory. Random variables, conditional expectation, moment generating functions, modes of convergence, the normal distribution and the central limit theorem.
- Modelling financial markets in discrete time. Binomial tree models. Arbitrage-free pricing. Portfolios. Risk-neutral probabilities. Discrete-time martingales.
- Modelling financial markets in continuous time. Brownian motion, quadratic variation, continuous-time martingales.
- Refresher on key calculus concepts: the Riemann integral, the heat equation.
- Introduction to stochastic calculus: the Ito integral, Ito processes, Ito's formula. Stochastic differential equations.
- The Black-Scholes market: pricing contingent claims via replicating portfolios. The Black-Scholes partial differential equation. Change of measure, Girsanov's theorem, and applications to pricing. The risk-neutral valuation formula.
- Numerical and computational methods for pricing: Monte Carlo methods, finite-difference methods.
- Further topics to be chosen from: Delta and Gamma hedging, exotic options, Feynman-Kac formula, limitations of the Black-Scholes model.
Learning Outcomes
Subject-specific Knowledge:
- Advanced understanding of the principles and practice of probabilistic pricing methods for financial products.
- Advanced understanding of the concepts of arbitrage, risk-neutral measures, and market equilibirum used in the pricing of financial derivatives.
Subject-specific Skills:
- By the end of the module, students should have developed highly specialised and advanced technical, professional and academic skills that enable them to:
- formulate and solve problems in asset allocation and portfolio management;
- develop trading strategies and use appropriate models to evaluate performance.
- Ability to apply arbitrage-free pricing theory to models of financial markets formulated either in discrete or continuous time.
- Ability to derive mathematical properties of stochastic models for financial systems formulated via stochastic differential equations, using the methods of stochastic calculus.
- Ability to select and apply appropriate probabilistic reasoning to developing pricing theories for models in appropriate financial markets, using the concepts of arbitrage, risk-neutral measures, and portfolio theory.
- Ability to apply appropriate analytical, Monte Carlo, or numerical methods to price financial products.
Key Skills:
- Students will have basic mathematical skills in the following areas: problem solving, modelling, computation.
Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module
- Lectures demonstrate what is required to be learned and give a thorough justification of the theoretical developments, with appropriate examples.
- Problems classes will demonstrate the application of the theory to extended examples.
- Computer practicals will, through guided worksheets, enable the students to apply some of the computational methods developed in the course to concrete problems.
- Take-home examinations will assess students' ability to develop mathematically sound arguments in the context of financial models, to apply probabilistic reasoning and methods to analyse financial products, and to employ a variety of tools to correctly price financial products.
