We study portfolio optimization of four major cryptocurrencies. Our time series model is a generalized autoregressive conditional heteroscedasticity (GARCH) with multivariate normal tempered stable (MNTS) distributed residuals used to capture the non-Gaussian cryptocurrency return dynamics. Based on model, we optimize in terms Foster-Hart risk. Those sophisticated techniques are not yet documen...

Estimations and forecasts of the covariance matrix are made for the EUR/SEK and USD/SEK, whereby the forecasts are used in a pract...

In this paper we focus on the impact of additive level outliers on the calculation of risk measures such as minimum capital risk requirements and four possible alternatives of reducing these measures’ estimation biases. The first and second alternatives are based on wavelets while the third is based on the traditional proposals in the literature and the three are based on the detection and corr...
