Stochastic Calculus and Derivatives

Introduksjon

Please note that this is a preliminary course description. The final version will be published in June 2026.

This course provides a rigorous yet practical introduction to derivative securities and the stochastic calculus tools used to price and hedge them. Students will explore key concepts such as no-arbitrage pricing, the binomial and Black-Scholes models, and the use of stochastic differential equations in financial modeling. Topics include delta hedging, exotic options, credit risk, and numerical methods for option valuation. Emphasis is placed on both theoretical foundations and real-world applications in modern financial markets.
