This paper constructs an alternative investment strategy to portfolio optimization model in the framework of the Mean–Variance portfolio selection model. To differentiate it from the ubiquitously applied Mean–Variance model, which is constructed on an assumption that returns are normally...

A discrete time probabilistic model, for optimal equity allocation and portfolio selection, is formulated so as to apply to (at least) reinsurance. In the context of a company with several portfolios (or subsidiaries), representing both liabilities and assets, it is proved that the model has...

In this paper we give a resume of the correlation concept that underlies the models for credit risk measurement, for the rating of structured products, for the pricing of (tranches of) structured products, and for Basel II capital charges. We discuss how securitization has changed the risk...

The article covers a brief piece of proprietary research exploring a relatively new machine learning approach to enhance portfolio optimisation problems: the TIC (Theory-Implied Correlation) matrix approach. This new approach allows to factor qualitative information into the portfolio...

Index tracking has long been of interest for both industry of fund management andacademia. Various methods have been proposed and tested and various issues arediscussed throughout the past 30 years. Yet one issue remains unresolved is how toperform stock selection optimally. In this paper, I...

In this paper, I present the implementation of Portfolio Risk Measures in Python 3.5. Several Risk Measures such as VaR, CVaR and MVaR are adopted and different methodologies of computation are showed: Parametric and Historical. The portfolio is dinamical in the sense that each day computes the...

Arguments on the existence of dynamic arbitrage and price manipulation strategies are often invoked to guide modeling price impacts of large trades. We revisit the concept of dynamic arbitrage in illiquid markets in the presence of time-varying stochastic price impact functions and a broad class...

We revisit the question whether commodities should be included in investors' portfolios. We employ for the first time a stochastic dominance efficiency (SDE) approach to construct optimal portfolios with and without commodities and we evaluate their comparative performance. SDE circumvents the...

The purpose of this research is the realistic forecast of volatility in frame of a risk parity class of strategies. The custom rescaling of volatility – naïve risk parity - doesn't consider market inefficiencies which correspond to cyclical patterns like crisis and the following recovery. The...

Since Target Date Funds (TDFs) became one of the default investment strategies for the 401(k) defined contribution (DC) beneficiaries, they have developed rapidly. Usually they are structured according to the principle “young people should invest more in equities”. Is this really a good...
