MATH6131 Financial Mathematics

Module Overview

This module provides a solid mathematical introduction to the subject of Compound Interest Theory and its application to the analysis of a wide variety of complex financial problems, including those associated with mortgage and commercial loans, the valuation of securities, consumer credit transactions, and the appraisal of investment projects. The investment and risk characteristics of the standard asset classes available for investment purposes are also briefly considered, as is the topic of asset-liability matching. The module also provides introductions to the term structure of interest rates, simple stochastic interest rate models, the concept of no-arbitrage pricing of forward contracts, and behavioural economics. Pre-requisite for MATH6127

Aims and Objectives

Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

  • Use a generalised cash-flow model to describe financial transactions
  • Apply discounted cash flow techniques to the valuation of securities, including the effects of taxation
  • Demonstrate an understanding of the term structure of interest rates.
  • Describe the main investment and risk characteristics of the standard asset classes available for investment purposes
  • Calculate the discounted mean term or volatility of an asset or liability and analyse whether an asset-liability position is matched or immunized
  • Demonstrate an understanding of the nature and use of simple stochastic interest rate models.
  • Calculate the forward price and value of a forward contract using no-arbitrage pricing
  • Take into account the time value of money by using the concepts of compound interest and discounting.
  • Demonstrate how interest rates and discount rates change when the underlying time period is altered
  • Calculate the present value and accumulated value of a cash flow of equal or unequal payments, at a specified rate of interest, and at a real rate of interest, assuming a given rate of inflation.
  • Define and use standard compound interest functions.
  • Analyse straightforward compound interest problems, and solve resulting equations of value, including for the implied rate of return
  • Describe how a loan may be repaid by regular instalments of interest and capital.
  • Apply discounted cash flow techniques to investment project appraisal.
  • Demonstrate an understanding of behavioural economics

Syllabus

- Simple and compound interest. Time value of money. Rate of interest, rate of discount, and force of interest. Accumulated values and discounted values. Accumulation and discounting of a (possibly infinite) cash flow to a given time, where both the rate of cash flow and the force of interest may be time-varying. - Relationships between rates of interest and discount over different time periods. Nominal rates, effective rates, rates payable multiple times per annum. - Definition of the standard compound interest functions and relationships between them. - Generalised cash flow modelling. Equation of value for a cash flow problem, and methods of solution. - Loans. Equation of value corresponding to periodic repayment of a loan. Interest and capital content of annuity payments where the annuity is used to repay a loan. Consumer credit transactions. Annual Percentage Rate of Charge (APR). - Net present value (NPV), accumulated profit, and internal rate of return (IRR) for investment projects. - Investment project appraisal using NPV and IRR. Real rate of return in presence of inflation. - Behavioural economics. Expected utility theory, prospect theory, framing, heuristics, and biases. The Bernartzi and Thaler solution to the equity premium puzzle. - Ordinary shares. Constant dividend growth model of share valuation. Fixed-interest securities. Present value and redemption yield for a fixed-interest security, including effects of taxation. - Yield curves and the term structure of interest rates. - Investment and risk characteristics of standard asset classes (Government fixed-interest securities, other fixed-interest securities, equities, etc.) available for investment purposes. - Discounted mean term, volatility, convexity. Matching of assets and liabilities, immunization. - Simple stochastic interest rate models. Mean, variance, and distribution function for the accumulated amount of an initial investment, and applications. - Spot and forward interest rates. Forward contracts. The concept of no-arbitrage pricing and its use in determining the fair value of a forward contract.
