 Unit code: MATH20912 Credit Rating: 10 Unit level: Level 2 Teaching period(s): Semester 2 Offered by School of Mathematics Available as a free choice unit?: N

None

#### Aims

The course unit unit aims to enable students to acquire active knowledge and understanding of some basic concepts in financial mathematics including stochastic models for stocks and pricing of contingent claims.

#### Overview

This course is intended to serve as a basic introduction to financial mathematics. It gives a mathematical perspective on the valuation of financial instruments (futures, options, etc.) and their risk-management. The purpose of the course is to introduce students to the stochastic techniques employed in derivative pricing.

#### Learning outcomes

On completion of this unit successful students will be able to:

• Compare the value of standard financial contracts such as stocks, bonds and options at different times using a risk-free discount factor.
• Calculate the expected value of a portfolio under a subjective probability measure.
• Sketch payoff diagrams for a variety of portfolios, and be able to predict what the effect of changing the portfolio will be.
• Construct no-arbitrage arguments to derive upper and lower bounds of financial contracts and exploit arbitrage opportunities.
• Construct hedging arguments for the discrete one-step binomial model and the continuous Black-Scholes model.
• Calculate the expected value of a financial contract under the risk-neutral measure using a binomial-tree.
• Derive the analytic formula and perform analysis on both the value and the ‘Greeks’ of a financial contract.
• Derive the analytic formula for a bond with coupons, and perform analysis on the value of the financial contract.

#### Feedback methods

Feedback tutorials will provide an opportunity for students' work to be discussed and provide feedback on their understanding.  Coursework or in-class tests (where applicable) also provide an opportunity for students to receive feedback.  Students can also get feedback on their understanding directly from the lecturer, for example during the lecturer's office hour.
