This article builds on the mean-variance criterion and the connection with expected utility maximization to define optimal portfolios. In addition, it extends the results by considering the use of step utility functions, which are non-continuous and able to capture possible preferences...

Stochastic volatility models are very flexible models able to characterize financial volatility evolution. This article explores computational capabilities based on Graphical Processing Units to simulate many Monte Carlo Markov chains in estimating stochastic volatility model parameters through...
