We propose a new class of mappings, called Dynamic Limit Growth Indices, that are designed to measure the long-run performance of a financial portfolio in discrete time setup. We study various important properties for this new class of measures, and in particular, we provide necessary and...

It is shown that the the popular least squares method of option pricing converges even if the underlying is non-Markovian, the pay-offs are path dependent and with a very flexible setup for approximation of conditional expectations. The main benefit is the increase of freedom in creating...

In this paper we provide a mathematical illustration to an empirical fuzzy phenomena known as 20-60-20 rule. In particular we show that if a random vector follows multivariate normal distribution and we split the whole population into three groups, then this fixed ratio leads to a global...

In this paper we provide a unified and flexible framework for study of the time consistency of risk and performance measures. The proposed framework integrates existing forms of time consistency as well as various connections between them. In our approach the time consistency is studied for a...
