Modeling the dependency between stock market returns is a difficult task when returns follow a complicated dynamics. It is not easy to specify the multivariate distribution relating two or more return series. In this paper, a methodology based on fitting ARIMA, GARCH and ARMA-GARCH models and copula functions is applied. In such methodology, the dependency parameter can easily be rendered condi...

Traditionally, this implies that the returns between the index and the portfolio should differ as little as possible. However, investors might happily accept positive deviations (ie, returns higher than the index’s) while being particularly concerned with negative deviations. In this chapt...

We investigate a portfolio optimization problem under the threat of a market crash, where the interest rate of the bond is modeled as a Vasicek process, which is correlated with the stock price process.
