Pre, Co-requisites Warning

Unless you have either the requisites for this course or written special permission from your Dean to enroll in
it, you may be removed from this course and it will be deleted from your record. You can be deregistered at

                                                                Course Objectives


This course is about modern financial mathematics -- the study of making financial decisions under
uncertainty. Such decisions are shaped by three main drivers – the balance between future and present,
quantified by the interest rate; the role of uncertainty, often quantified in terms of the volatility, and
investors attitudes toward risk. Several products are available to trade and manage risk: stocks and bonds
at a basic level; forwards, futures, and options at a more advanced level. We will develop theories for pricing
and hedging both individual securities and portfolios of them. By the end of the course we will understand
two Nobel-prize winning economic theories – the Capital Asset Pricing Model of Markowitz, Sharpe, and
Miller (Nobel Prize 1990) and the Black-Scholes-Merton theory of options pricing (Nobel Prize 1997).
We will learn how to price and hedge a variety of stock options and briefly discuss the challenges involved
in extending this pricing technology to options on other underlying assets. Along the way we will use
mathematics ranging from basic stochastic calculus and linear differential equations to the asymptotic
expansion of integrals.

The topics covered are:

1) Intuition about uncertainty and risk

2) The classical approach to decision making under uncertainty

3) Repaying loans over time

4) Bond pricing with default: using difference equations

5) Tranching and collateralized debt obligations

6) Modeling stock prices

7) Mean-variance portfolio optimization

8) A qualitative introduction to options

9) Pricing options using binomial trees

10) Random walks

11) Black Scholes PDE for pricing options in continuous time

12) Solving the Black Scholes PDE

13) Some approximate values of the Black Scholes call formula

Assignments and/or Quizzes


I will be assigning questions as we go for your practice at home. The midterms and the final exam will use
some of these questions and material from the textbook and lecture notes.


Midterms or Tests



Midterm test 1 (Thursday, February 15, 7-9PM, in TC205)

Midterm test 2 (Thursday, March 15, 7-9PM, in TC205)


Final Exam



The final exam will be on April 14, 2:00-4:00pm in SH 2355. It will cover all of the course material.


Evaluation



Midterm 1 - 25%

Midterm 2 - 25%

Essay - 10%

Final Exam - 40% 

                                            Computing and/or Calculator Requirement


Only basic scientific calculators will be allowed in tests or exams (to be precise, calculators with a memory
buffer smaller than 10 characters).


                                          Department Policy on Missed Course Requirements


If you are unable to meet a course requirement due to illness or other serious circumstances, you must
provide valid medical or other supporting documentation to your Dean's office as soon as possible, and
contact your instructor immediately. If accommodation is approved by your Dean's office, your instructor
will be notified, then it is your responsibility to make alternative arrangements with your instructor. In
the event of a missed final exam, a "Recommendation of Special Examination" form must be obtained
from the Dean's Office immediately. For further information please see:
http://www.stats.uwo.ca/accommodation_medical.pdf.
A student requiring academic accommodation due to illness, should use the Student Medical Certificate
when visiting an off-campus medical facility. The form can be found at:
http://www.stats.uwo.ca/medicalform.pdf.
Or, request a Record's Release Form (located in the Dean's Office) for visits to Student Health Services.

Missed Midterm or Quiz: The policy of the department of Statistical and Actuarial Sciences is that there
will be no make-up exams or quizzes for a missed midterm or a quiz. For those that do legitimately miss a
midterm or a quiz and provide the required supporting documentation, the standard practice will be that
the weight of the midterm or the quiz will be reassigned to the final exam. If your reason is not deemed
valid, then you will receive a mark of 0.

Student Health and Wellness: As part of a successful student experience at Western, we encourage students
to make their health and wellness a priority. Western provides several on campus health-related services to
help you achieve optimum health and engage in healthy living while pursuing your degree. For example, to
support physical activity, all students, as part of their registration, receive membership in Western’s Campus
Recreation Centre. Numerous cultural events are offered throughout the year. Please check out the Faculty of
Music web page http://www.music.uwo.ca/, and our own McIntosh Gallery http://www.mcintoshgallery.ca.
Information regarding health- and wellness-related services available to students may be found at
http://www.health.uwo.ca/.  Students seeking help regarding mental health concerns are advised to speak to
someone they feel comfortable confiding in, such as their faculty supervisor, their program director (graduate
chair), or other relevant administrators in their unit. Campus mental health resources may be found at
http://www.health.uwo.ca/mental_health/resources.html.  To help you learn more about mental health,
Western has developed an interactive mental health learning module, found here:
http://www.health.uwo.ca/mental_health/module.html. This module is 30 minutes in length and provides
participants with a basic understanding of mental health issues and of available campus and community
resources. Topics include stress, anxiety, depression, suicide and eating disorders. After successful completion
of the module, participants receive a certificate confirming their participation.


                                                            Email Communication


E-mail can be an efficient and effective way to communicate with your Professor, but it should be used
very rarely, only to provide us with information or to ask a question that requires a very brief response. 
I do not wish to see emails that ask “What did I miss in class today?”.  For more lengthy discussions, you
should raise questions after class or during office hours, or make a separate appointment if necessary. 
Please remember that I will only read e-mails from your UWO student account. The subject line should
contain “SS2857”. E-mails from other accounts (e.g. hotmail, yahoo, etc.) will not be read.  Please conduct
yourselves professionally if you choose to e-mail your Professor.

                                                                      Attendance


Classroom attendance is viewed as an important part of the learning process. Students are advised that
excessive absenteeism may result in the student being disbarred from the final exam (see Western
Academic Calendar).

                                                            Classroom Environment


The Department has adopted a "Mutual Expectations" policy governing the classroom environment and
all work submitted by students. The full text of the policy can be found at:
http://www.stats.uwo.ca/mutual_expectations.pdf.
In summary, the policy was developed under the premise that all interactions between students and faculty
should be governed by the principles of courtesy, respect and honesty.
