The unit aims to provide a concise mathematical formulation of the main characteristics of financial instruments, with an emphasis on quantitative aspects of stock price, options, and other financial derivatives.
Brief Description of the unit
Derivative securities (such as options) depend on the values of primary securities (such as stock or bond prices). During the last thirty years trading in derivative securities have undergone a tremendous development, and nowadays derivative securities are traded on markets all over the world in large numbers. The purpose of the course is to exhibit basic features of advanced financial derivatives, starting with basic model specifications, introducing the concept of arbitrage, and ending with a risk-neutral valuation formula and its analysis.
On successful completion the students will have acquired active knowledge and understanding of some basic concepts and results in financial mathematics including:
- hedging strategies and managing market risk using derivatives;
- discrete and continuous time security markets;
- arbitrage, risk-neutral valuation, the fundamental theorem of asset pricing;
- European options: the Black-Scholes formula, American options;
- exotic options, weather, energy, and insurance derivatives, real options.
