Schedule

The course is offered during the Fall semester.
  • Class meeting dates: Please visit the University's academic calendar.
  • Schedule and Instructor: Please visit the University's schedule of classes for the instructor, time, and room.
  • Instructor and Teaching Assistant Office Hours: Please visit the Mathematical Finance program's office hour schedule.
Note: Please avoid stopping by the course assistant or instructor offices outside of their posted hours without an appointment. You are welcome to alert the instructor if you believe an assignment contains a typographical error, but the course assistants and instructor will rarely answer homework questions by email, except for students who are working full-time off campus and are unable to attend any scheduled office hour. We recommend emailing the instructor or teaching assistant in advance to alert them to your visit, as schedules can sometimes change unexpectedly.

Course Abstract

This course is an introduction to the mathematical theory of derivative security (or option) pricing. Fundamental concepts are briefly introduced first using the discrete-time binomial model: financial markets, derivative securities, arbitrage, hedging and replicating portfolios, risk-neutral probabilities, risk-neutral pricing formula, and market completeness. Basic ideas of probability and stochastic processes are reviewed for finite probability spaces and discrete-time processes: conditional expectation, martingales, and Markov processes. After this introduction to finance using discrete-time models, the emphasis shifts to continuous-time models and the main part of the course. Topics covered include a summary of probability measure theory and conditional expectation, Brownian motion and quadratic variation, martingales, Ito integral, stochastic calculus, replicating portfolios and hedging, Black-Scholes-Merton formulae for a European-style call option price, change of measure and Girsanov's Theorem, risk-neutral pricing pricing theory, no-arbitrage and existence of risk-neutral measure, market completeness and uniqueness of risk-neutral measure, Markov property, Feyman-Kac theorem and the connection between stochastic calculus and partial differential equations, and local volatility and stochastic volatility models.

Pre-requisites and Co-requisites

Ordinary differential equations (01:640:244 or 01:640:252), multivariable calculus (01:640:251), linear algebra (01:640:250), and undegraduate probability theory with calculus (01:640:477 or 01:960:381). An undergraduate course on analysis (01:640:311-312 or 01:640:411-412) or engineering mathematics (01:640:421) or partial differential equations (01:640:423) is recommended but not required.

Please visit the prerequisites page for descriptions of Rutgers undergraduate course prerequisites. A solid understanding of undergraduate probability at the level of the textbook by Sheldon Ross, A First Course in Probability, is especially important. Given this background, the course should be accessible to Mathematical Finance master's degree students and graduate students in Computer Science, Economics, Finance, Engineering, Mathematics, Physics, Operations Research, and Statistics.

Sakai

All course content – lecture notes, homework assignments and solutions, exam solutions, supplementary articles, and computer programs – are posted on Sakai and available to registered students.

Grading

Class attendance 5%, homework 25%, midterm exam 30%, and final exam 40%. Exams are in-class.

Class Policies

  • Class attendance: Attendance is taken every week and students will be dropped from the course for missing an excessive number of class periods. Students can be absent for one week (two periods) without an excuse. Additional absences must be excused in writing. Unexcused absences will negatively impact course grade.
  • Homework: Assignments may be submitted at the beginning of class each week only – assignments left in mailboxes, under office doors, given to departmental staff, emailed, faxed, or mailed are not accepted. No late homework is accepted, for any reason – instead, the two (2) lowest scores are dropped. Students may work together on assignments provided their submissions represent fair individual efforts. Assignments must be legible, stapled (no paper clips or loose sheets), and use US letter-size paper.
  • Exam attendance: Make-up exams are not permitted. In a genuine emergency, such as a documented medical condition, students are expected to contact the instructor in advance or as soon as possible after the event.
  • Incomplete grades: Incomplete grades are not given. Students who do not have adequate preparation or time to complete assignments or study for exams during the semester should not take the course.
  • Academic integrity: Students are expected to adhere to the academic integrity code.
  • Work-study balance: If you work part or full time, please read our guidelines for balancing work and study.
  • Withdrawal dates: You are responsible for being aware of all deadlines, including those for course refunds or withdrawals. Please contact the Registrar if you are in any doubt regarding drop or refund deadlines.
