ST339 Introduction to Mathematical Finance
Throughout the 202122 academic year, we will be adapting the way we teach and assess your modules in line with government guidance on social distancing and other protective measures in response to Coronavirus. Teaching will vary between online and oncampus delivery through the year, and you should read the additional information linked on the right hand side of this page for details of how this will work for this module. The contact hours shown in the module information below are superseded by the additional information. You can find out more about the University’s overall response to Coronavirus at: https://warwick.ac.uk/coronavirus.
All dates for assessments for Statistics modules, including coursework and examinations, can be found in the Statistics Assessment Handbook at http://go.warwick.ac.uk/STassessmenthandbook
ST33915 Introduction to Mathematical Finance
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.
Prerequisites:
Statistics Students: ST218 Mathematical Statistics A
NonStatistics 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.
Module aims
To provide an introduction to Mathematical Finance in discrete time and cover the discrete part of the actuarial syllabus.
To be able to evaluate and interpret the theory of mathematical finance in discrete time and to apply theoretical concepts to construct stochastic models of financial markets.

b) Maximising the expected return
c) The meanvariance problems
d) The case without a riskless asset
e) The case with a riskless asset
f) The Markowitz tangency portfolio and the capital market line
g) Meanvariance equilibria
h) The Capital Asset Pricing Model (CAPM)  Utility Theory
a) Preferences on lotteries
b) Von NeumannMorgenstern representation
c) Concave functions and Jensen’s inequality
d) Expected utility representation
e) Measuring risk aversion
d) A primer on utility maximisation  Introduction to Risk Measures
a) Monetary measures of risk
b) Value at Risk and Expected Shortfall  Pricing and Hedging in Finite Discrete Time
a) Conditional expectations
b) Filtrations and martingales
c) Financial markets in finite discrete time
d) Selffinancing strategies
e) The Fundamental Theorem of Asset Pricing revisited
f) Valuation of contingent claims
g) Complete markets
h) Pricing and hedging in the binomial model
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 meanvariance 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 selffinancing strategies and absence of arbitrage, hedge derivate products in complete and incomplete markets in discrete time
