Hull, “Options, Futures, and Other Derivatives”, Prentice Hall, 10th edition (other editions – within reason – also work!) There’s a solutions manual – not mandatory, but handy Dear professor, I am currently doing my internship at Goldman Sachs in London in the Securities division and wanted to thank you for the course in Options and Futures. It has been very helpful and I am going back to the slides you have provided us with. The book by Hull is everywhere in the floor and it is considered the “bible”! Yes ▪ I will assume a solid knowledge of basic financial mathematics, prob & stats, and calculus Why? ▪ Valuing derivatives relies on mathematical techniques – hard to say anything otherwise ▪ Many tasks you will face on the job require you to know that math: using and/or writing computer code for pricing, estimating VaR, designing new products, etc. ▪ Anyone can commit a formula to memory. Understanding where it comes from is more challenging and rewarding! Lectures Case studies Problem sets “Take-home” mid-terms Final exam Wed & Thu Check Blackboard regularly Largely follow the textbook, but: ▪ There will be textbook material we don’t go over in class – still exam material, unless otherwise stated ▪ There will be enhancements Hybrid mode Participation: Making a comment… < 1 time in 3 classes – don’t be too shy! > 3 times in 1 class – let others speak too! This course is hands-on ▪ Develop critical thinking ▪ Practice theory encountered in class ▪ Application to challenging real-world problems Key component of business education worldwide Great for practice We will see some examples in class, but you should practice on your own Solving problems is how we learn The spirit: Apply the tools we learn in class, to find a solution to problems we have not seen before Two (2) “take-home” mid-terms ▪ Distributed via BlackBoard ▪ Per test: Two shots, over a one-week period Can account for 30% of your grade, for the first time you take the exam Expiration: Any retake means you forfeit the take-home mid-terms grades, and your grade is 100% based on the exam Partly about solving problems ▪ Similar to problem sets ▪ We will see some in class Partly about applying the theory and discussing its applications ▪ Similar to the kind of discussions we have in class ▪ Plenty of examples to develop intuition Difficulty Unreasonably difficult, impossible to pass Ridicolously easy, guaranteed pass Dec Jan I Jan II Jul Sep First take of the exam: max { 70% × Final exam score + 15% × Take-home mid-term #1 + 15% × Take-home mid-term #2 ; 100% × Final exam score Any retake: 100% × Final exam grade } I can only write one for you if I know you – participate in the class discussion! I need time to write one! ▪ Ask me at least two months before your deadline My letter will mention your performance on my course (would not be credible otherwise) The starting point should be your own idea I’m happy to supervise empirical work ▪ Final paper ≠ Summary of a bunch of papers you have read ▪ Get your hands dirty with data Working on a BSc thesis will not affect your grade on this course in any way 1973 1997 The Black-Scholes formula: 𝐶 = 𝑆0 𝑁 𝑑 − 𝐾𝑒 −𝑟𝑇 𝑁 𝑑 − 𝜎 𝑇 where: 𝑑= 𝑆 𝜎2 ln 𝐾 + 𝑟 + 2 𝜎 𝑇 𝑇 1998 2003 .
