[edit] Material
Attendants of the course may download the presentation sheets from: Sheets
[edit] Software
Computational activities of the course are based on the language R. The examples on the presentation sheets are presented as R-code which requires the package QuantLab.
R can be obtained as free software from R-homepage.
The package QuantLab of R-functions can be downloaded and installed from Package.
In order to make use of this package proceed as follows:
- download and install R (use the self-extracting .exe-file)
- download the .zip-file of the QuantLab package to some voluntary directory
- start R (use the GUI under Windows)
- use Menu: File -> Packages -> Install packages form local zip-Files, to install the package QuantLab
- execute: library(QuantLab)
Now the package should be loaded.
- use the menu item Help -> HTML Help
- click: Packages
- click: QuantLab
- study: QuantLab-package
- click the commands and enjoy the examples (located at the end of QuantLab-package)
In order to learn the basics of R study the [manual]
[edit] Exam
The exam will consist of eight question, sampled from the list below. The sheets of the course can be used during the exam. The answers should be given in a handwritten form.
- Describe in words the binomial model and show that NA holds iff d < er(T − t) < u.
- Describe the single-period lognormal model. Explain the parameters of the model.
- Prove for a single period model: If NA is satisfied, then prices of admissible portfolios are uniquely determined.
- Explain the concept of a forward price.
- State and explain the put-call parity for binary options.
- Show for the single-period binomial model: NA holds iff there exist a risk neutral probability.
- Show for the single period binomial model: The risk neutral probability is unique.
- For a single period model: Explain the concept of risk neutrality. Discuss the lognormal case.
- On sheet 39 the formula for the Delta in the last line is wrong. What is the correct formula and why ?
- Explain in words (and handwritten diagrams) why an American Call and a European Call (on a non-dividend paying stock) have the same price. What about Puts ? (Distinguish the cases r > 0 and r = 0.)
- Discuss for a multiperiod binomial model: What is the influence of jump height and jump probability on the price of a derivative ? What does this mean for the lognormal approximation of the binomial model ?
