Intermediate Mathematics Understanding Stochastic Calculus
Training
Provided by London Financial Studies
Course Outline
The use of Probability theory in financial modelling can be traced back to the work on Bachelier at the beginning of last century with advanced probabilistic methods being introduced for the first time by Black, Scholes and Merton in the seventies. The modern financial quantitative analysts make use of sophisticated mathematical concepts, such as martingales and stochastic integration, in order to describe the behaviour of the markets or to derive computing methods.
Who The Course is For
Quantitative analysts, financial engineers, researchers, risk managers, structurers, market analysts and product controllers. Past participants have included: Chief investment officers, Asset Managers, Strategists, Private Banks, Relationship Managers
Prior Knowledge:
Delegates should have a good understanding of Elementary Probability Theory, Calculus and Linear Algebra (covered in Maths Refresher).
