Stochastic processes are models that reflect the wide variety of unpredictable ways in which reality behaves. In this course we study several examples of stochastic processes, and analyze the behavior they exhibit. We apply this knowledge to mathematical finance, in particular to arbitrage free pricing and the Black-Scholes model.
Prerequisites: MAS113 (Introduction to Probability and Statistics); MAS221 (Analysis); MAS223 (Statistical Inference and Modelling) [recommended]; MAS275 (Probability Modelling)
Not with: MAS452 (Stochastic Processes and Finance)
No other modules have this module as a prerequisite.
- Stochastic Processes: We introduce conditional expectation and martingales, which are used to study the behavior of stochastic processes such as random walks, urn models, branching processes, Brownian motion and diffusions. Stochastic integration with respect to Brownian motion is introduced.
- Stochastic Finance: We study the key concept of arbitrage and arbitrage free pricing, both in finite markets and in the continuous time Black-Scholes model.
- Introduce probability spaces, σ-fields and conditional expectation.
- Introduce martingales and study their basic properties.
- Analyse the behaviour of different types of stochastic process, such as random walks, urn models and branching processes.
- Explain the role of arbitrage and arbitrage free pricing.
- Use finite market models to price and hedge a range of financial derivatives.
- Introduce Brownian motion and study its basic properties.
- Introduce stochastic calculus, Ito's formula and stochastic differential equations.
- Derive the Black-Schole's formula in continuous time and use it to price a range of financial derivatives.
- Study extensions of the Black-Scholes formula.
- Study various examples of stochastic processes.
- Use martingales and related tools to study the behavior of stochastic processes.
- Price and hedge financial derivatives, using both finite market models and the continuous time Black-Scholes formula.
