Leptokurtic portfolio theory [PDF]

open access: yesThe European Physical Journal B - Condensed Matter and Complex Systems, 2006
The question of optimal portfolio is addressed. The conventional Markowitz portfolio optimisation is discussed and the shortcomings due to non-Gaussian security returns are outlined. A method is proposed to minimise the likelihood of extreme non-Gaussian drawdowns of the portfolio value.

A Theory of Patent Portfolios [PDF]

open access: yesSSRN Electronic Journal, 2013
This paper develops a theory of patent portfolios in which firms accumulate an enormous amount of related patents, which makes it impractical to develop new products that avoid inadvertent infringement. We show that patent peace arises if product market competition is weak and patent portfolios are either sufficiently weak or sufficiently strong with ...

Multi-period uncertain portfolio selection model with prospect utility function.

open access: yesPLoS ONE, 2022
In this paper, we discuss a multi-period portfolio optimization problem based on uncertainty theory and prospect theory. We propose an uncertain multi-period portfolio selection model, in which the return utility and risk of investment are measured by ...

Credibilistic variance and skewness of trapezoidal fuzzy variable and mean–variance–skewness model for portfolio selection

open access: yesResults in Applied Mathematics, 2021
The fuzzy set theory is widely used to describe the uncertainty of financial markets in modern portfolio selection problems. In this study, the credibility theory (a popular branch of the fuzzy set theory) is applied to extend Markowitz’s mean–variance ...

Deep Portfolio Theory

open access: yesCoRR, 2016
We construct a deep portfolio theory. By building on Markowitz's classic risk-return trade-off, we develop a self-contained four-step routine of encode, calibrate, validate and verify to formulate an automated and general portfolio selection process.
