Please note

Students are not permitted to take, for credit, MATH49102 in an undergraduate programme and then MATH69012 in a postgraduate programme at the University of Manchester, as the courses are identical.

Aims

The unit aims to provide a concise mathematical formulation of the main characteristics of financial instruments, with an emphasis on quantitative aspects of stock price, options, and other financial derivatives.

Overview

Derivative securities (such as options) depend on the values of primary securities (such as stock or bond prices). During the last thirty years trading in derivative securities have undergone a tremendous development, and nowadays derivative securities are traded on markets all over the world in large numbers. The purpose of the course is to exhibit basic features of advanced financial derivatives, starting with basic model specifications, introducing the concept of arbitrage, and ending with a risk-neutral valuation formula and its analysis.

Learning outcomes

On successful completion the students will have acquired active knowledge and understanding of some basic concepts and results in financial mathematics including:

  • hedging strategies and managing market risk using derivatives;
  • discrete and continuous time security markets;
  • arbitrage, risk-neutral valuation, the fundamental theorem of asset pricing;
  • European options, exotic options, American options;
  • interest rate models and interest rate derivatives;

Future topics requiring this course unit

None.
