Functional Portfolio Optimization in Stochastic Portfolio Theory

open access: yesSIAM Journal on Financial Mathematics, 2022
In this paper we develop a concrete and fully implementable approach to the optimization of functionally generated portfolios in stochastic portfolio theory. The main idea is to optimize over a family of rank-based portfolios parameterized by an exponentially concave function on the unit interval. This choice can be motivated by the long term stability

Optimalisasi Portofolio Kredit untuk Perencanaan Ekspansi Kredit pada Perbankan Nasional

open access: yesJurnal Aplikasi Bisnis dan Manajemen, 2020
The aim of this study is to determine the portfolio performance in each economic sector based on return and risk of portfolio credit at 3 Sentra Kredit Menengah (SKM) under BNI WJS supervision and to find out the optimal combination or composition of the

Constrained Dynamic Mean-Variance Portfolio Selection in Continuous-Time

open access: yesAlgorithms, 2021
This paper revisits the dynamic MV portfolio selection problem with cone constraints in continuous-time. We first reformulate our constrained MV portfolio selection model into a special constrained LQ optimal control model and develop the optimal ...

Optimal characteristic portfolios

open access: yesQuantitative Finance, 2020
Characteristic-sorted portfolios are the workhorses of modern empirical finance, deployed widely to evaluate anomalies and construct asset pricing models. We propose a new method for their estimation that is simple to compute, makes no ex-ante assumption on the nature of the relationship between the characteristic and returns, and does not require ad ...

A Selective Portfolio Management Algorithm with Off-Policy Reinforcement Learning Using Dirichlet Distribution

open access: yesAxioms, 2022
Existing methods in portfolio management deterministically produce an optimal portfolio. However, according to modern portfolio theory, there exists a trade-off between a portfolio’s expected returns and risks.

Robust Optimization of Credit Portfolios [PDF]

open access: yesMathematics of Operations Research, 2017
We introduce a dynamic credit portfolio framework where optimal investment strategies are robust against misspecifications of the reference credit model. The risk-averse investor models his fear of credit risk misspecification by considering a set of plausible alternatives whose expected log likelihood ratios are penalized.

Portfolio Optimization [PDF]

open access: yesASTIN Bulletin, 2000
AbstractBased on the profit and loss account of an insurance company we derive a probabilistic model for the financial result of the company, thereby both assets and liabilities are marked to market. We thus focus on the economic value of the company.We first analyse the underwriting risk of the company. The maximization of the risk return ratio of the

Foster–Hart optimal portfolios [PDF]

open access: yesJournal of Banking & Finance, 2016
We reinvestigate the classic portfolio optimization problem where the notion of portfolio risk is captured by the “Foster-Hart risk” — a new, bankruptcy-proof, reserve based measure of risk, extremely sensitive to left tail events (Foster and Hart, 2009).

ESTIMASI EXPECTED SHORTFALL DALAM OPTIMALISASI PORTOFOLIO DENGAN METODE DOWNSIDE DEVIATION PADA SAHAM IDXHEALTH

open access: yesE-Jurnal Matematika, 2023
Portfolio optimization using downside deviation is an optimal portfolio by defining the standard deviation of returns below the target (benchmark) as a level of risk measure. Every optimal portfolio certainly has risks.
