Notes on Stochastic Finance

چکیده
The values of the parameters r, t, St, T , and K used to price a call option via the Black-Scholes formula can be easily obtained from market data. Estimating the volatility coefficient σ can be a more difficult task, and several estimation methods are considered in this section with some examples of how the Black-Scholes formula can be fitted to market data. We cover the historical, implied, and local volatility models, and refer to [37] for stochastic volatility models.

متن کاملOptimization methods in portfolio management and option hedging
These lecture notes give an introduction to modern, continuous-time portfolio management and option hedging. We present the stochastic control method to portfolio optimization, which covers Merton’s pioneering work. The alternative martingale approach is also exposed with a nice application on option hedging with value at risk criterion. ∗Lectures for the CIMPA-IMAMIS school on mathematical fin...

The recent turmoil in financial markets has been partly caused by insufficient attention to rigorous financial modeling. Among the causes of this failing is the relative shortage of mathematically well trained professionals in the financial services industry. Shreve is a co-founder of one of the oldest and most successful masters degree programs in financial engineering, established at Carnegie...

متن کاملPDE for Finance Notes , Spring 2011 – Section 5
Stochastic optimal control. Stochastic optimal control is like deterministic optimal control except that (i) the equation of state is a stochastic differential equation, and (ii) the goal is to maximize or minimize the expected utility or cost. To see the structure of the theory in a simple, uncluttered way, we begin by examining what becomes of a standard deterministic utility maximization pro...
