Text: Robert L. McDonald, Derivative Markets, 2nd Edition (2015) Prentice Hall, ISBN 9780321280305

 

Responsible party: Milica Cudina March 2015

 

Description of the Course: This course is intended to provide the mathematical foundations necessary to prepare for a portin of the SoA Exam MFE and the "financial economics" portion of the CAS Exam 3.

Additionally, the course is aimed at building up the vocabulary and the techniques indispensable in the workplace at current financial and insurance institutions. This is not an exam-prep seminar.

The materal exhibited includes: an in depth study of the normal and log-normal distributions, the simple random walk, basics of stochastic calculus, the Samuelson (geometric Brownian motion) stock-price model and the Black-Scholes formula, analysis of option Greeks, market making, non-deteministic interest rate models (both discrete, and continuous-time), bond pricing, Monte-Carlo simulations.  The remainder of the Exam MFE/3F curriculum is exhibited in course M339d (also offered by the Department of Mathematics). 

Prerequisites:

(1) Formal: Introduction to Financial Mathematics for Actuaries M339D with a grade of at least C-.

(2) Actual: A thorough understanding and operational knowledge of (at least) classical calculus, calculus-based probability (with exphasis on the normal distribution), the term structure of interest rates, and the principles of risk-neutral pricing in the binomial asset-pricing model
