We address the problem of estimating risk-minimizing portfolios from a sample of historical returns, when the underlying distribution that generates returns exhibits departures from the standard Gaussian assumption. Specifically, we examine how the underlying estimation problem is influenced by marginal heavy tails, as modeled by the univariate Student-

ASYMPTOTICALLY OPTIMAL PORTFOLIOS
Mathematical Finance, 1992This paper extends to continuous time the concept of universal portfolio introduced by Cover (1991). Being a performance weighted average of constant rebalanced portfolios, the universal portfolio outperforms constant rebalanced and buy‐and‐hold portfolios exponentially over the long run.

Optimizing the possession portfolio
Current Opinion in Psychology, 2022Most consumers live surrounded by physical goods, some of which are used often and others that are largely neglected. In this article, we introduce the concept of a "possession portfolio" which we define as an individual's holistic sense (vs. an objective listing) of the totality of the physical goods they own at a given point in time.

Game-Theoretic Optimal Portfolios
Management Science, 1988We show, for a wide variety of payoff functions, that the expected log optimal portfolio is also game theoretically optimal in a single play or in multiple plays of the stock market. Thus there is no essential conflict between good short-term and long-run performance. Both are achieved by maximizing the conditional expected log return.

Optimal Sure Portfolio Plans [PDF]
Mathematical Finance, 1991 This paper is a sequel to the author's “Certainty Equivalence in the Continuous‐Time Portfolio‐cum‐Saving Model” in Applied Stochastic Analysis (eds. M. H. A. Davis and R. J. Elliot), where a model of optimal accumulation of capital and portfolio choice over an infinite horizon in continuous time was considered in which the vector process representing ...

Portfolio Optimization - Can Optimizing Portfolio Outperform Naive Diversification?
SSRN Electronic Journal, 2014In this study we examined the performances of mean-variance and tangency portfolio investment strategies in order to determine if optimal diversification has benefits over 1/N strategy.

Large-Scale Portfolio Optimization
Management Science, 1984This paper describes a practical algorithm for large-scale mean-variance portfolio optimization. The emphasis is on developing an efficient computational approach applicable to the broad range of portfolio models employed by the investment community. What distinguishes these from the “usual” quadratic program is (i) the form of the covariance matrix ...
