# FINANCIAL DERIVATIVES - 2019/0

Module code: PHY3048

## Module Overview

This module covers various different descriptions of diffusion, and the application of statistical physics to model share prices. This mathematics is then applied to calculating prices for some vanilla financial derivatives, followed by some exotic derivatives.

## Alternative Assessment

__Alternative assessment: __
None

## Assessment Strategy

The __assessment strategy__ is designed to provide students with the opportunity to demonstrate:

- Understanding of the concepts of derivative pricing, and underlying mathematics.

Thus, the

__summative assessment__for this module consists of:

- coursework assignment involving data analysis and computational modelling of financial instruments, and a final examination of 1.5h duration in which 2 questions from 3 must be answered.

__Formative assessment__

Many problem sets are issued during the course, and feedback will be given during tutorial sessions.

## Module aims

- The aims are to expose the students to the fundamentals of financial derivatives, to explore their underlying science by analogy to physical systems, and to show, by various methods, how the fair price of financial options may be determined.

Attributes Developed

**C** - Cognitive/analytical

**K** - Subject knowledge

**T** - Transferable skills

**P** - Professional/Practical skills

## Methods of Teaching / Learning

The __learning and teaching__ strategy is designed to:

Help students develop an understanding of how the ideas of Brownian processes can be applied to financial derivatives.

The __learning and teaching__ methods include:

33 hours of lecture classes/tutorials and computer-based problem-solving

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
