Introductory description

This module runs in Term 1 and is available for students on a course where it is a listed option and as an Unusual Option to students who have completed the prerequisite modules.

Pre-requisites:
Statistics Students: ST218 Mathematical Statistics A
Non-Statistics Students: ST220 Introduction to Mathematical Statistics

It is strongly recommended to take either MA359 Measure theory or ST342 Mathematics of Random Events alongside this module.

Results from this module will be partly used to determine exemption eligibility in the Institute and Faculty of Actuaries (IFoA) module CM2.

This module serves as a prerequisite for ST401 Stochastic Methods in Finance, IB357 Investment Management
IB359 Derivatives and Risk Management, IB394 International Financial Management and EC334 Topics in Financial Economics: Corporate Finance and Markets.

Learning outcomes

By the end of the module, students should be able to:

• Understand key notions of arbitrage and equivalent martingale measures in a one period financial market; calculate the set of equivalent martingale measures in a financial market
• Solve the mean-variance problems, understand the concept of the capital market line, describe the Capital Asset Pricing model including the principal results and assumptions
• Describe preference orders of financial investors, explain the concept of risk aversion, solve simple utility maximisation problems
• Explain the modern concept of monetary measures of risk, Calculate the Value at Risk and Expected Shortfall for given distributions
• Model financial markets in finite discrete time, describe self-financing strategies and absence of arbitrage, hedge derivate products in complete and incomplete markets in discrete time
