Conoscenze e abilità da conseguire

At the end of the course the student masters the main concepts of financial mathematics. The course will cover the stochastic dynamics of asset prices assumed under the efficient market theory, the concept of arbitrage-free pricing and replicating strategies, leading to the PDE approach to pricing.

  2. Plain vanilla contingent claims's pricing and hedging: forward and future, european and american options, pricing and hedging by arbitrage, self-financing portfolio, CRR's model, BS's model, volatility analysis and smile effect, arbitrage model for Ito's market, market premium and market numeraire, BS formula for exchange options, complete and incomplete markets;

Metodi didattici

Theoretical lessons will be support by applied examples of discussed models to incite students to find themselves the explicit solutions of the theoretical problems applying the correct mathematical instruments.

Modalità di verifica e valutazione dell'apprendimento

The learning test consists in a written exam to solve in 2 hours. This exam is composed by 3 execises which are structured into 2 questions each. During the exam it is permitted to use the calculator but it is not allowed to consult books or notes. It is attributed on average 10 points to each exercise. The students pass the exam with a score not lower than 18 points.

The students can ask also for an oral exam about all the programme of the course. The final grade will be the average of the oral and the witten exam's grade.

Strumenti a supporto della didattica

Teaching tools will be blackboard and slides.
