This course is available on the BSc in Financial Mathematics and Statistics, BSc in Mathematics and Economics and BSc in Mathematics with Economics. This course is available as an outside option to students on other programmes where regulations permit. This course is available with permission to General Course students.

Students must have completed Measure Theoretic Probability (MA321).

This course provides mathematical tools of stochastic calculus and develops the Black-Scholes theory of financial markets. It covers the following topics. Continuous-time stochastic processes, filtrations, stopping times, martingales, examples. Brownian motion and its properties. Construction of the Ito integral: simple integrands, Ito's isometry. Ito processes, Ito's formula, stochastic differential equations, Girsanov's theorem. Black-Scholes model: self-financing portfolios, risk neutral measure, risk neutral valuation of European contingent claims, Black-Scholes formula, Black-Scholes PDE, the Greeks. PDE techniques for derivative pricing. Implied volatility, basic ideas of calibration.

This course is delivered through a combination of classes and lectures totalling a minimum of 30 hours across  Lent Term. 

Written answers to set problems will be expected on a weekly basis. 

Lecture notes will be provided.
