Safety-first portfolio optimization : fixed versus random target

Singer, Nico - 2010 - This version: August 4, 2010

This paper analyzes the safety-first portfolio model under two different target assumptions, the fixed target, which is commonly assumed in the literature, and the random target, which has played only a minor role so far. As both targets can be easily motivated, the open question is, which...

Sample Selection Bias, Return Moments, and the Performance of Optimal versus Naive Diversification

Li, Bowei - 2016

I examine the sample selection bias in portfolio horse race. Numerous studies propose mean-variance portfolio rules to outperform the naive 1/N portfolio rule. However, the outperformance is often justified by a small number of pre-selected datasets. Using a new performance test based on a large...

Does It Pay to Invest in Art? A Selection-Corrected Returns Perspective

Korteweg, Arthur - 2017

This paper shows the importance of correcting for sample selection when investing in illiquid assets that trade endogenously. Using a sample of 32,928 paintings that sold repeatedly between 1960 and 2013, we find an asymmetric V-shaped relation between sale probabilities and returns. Adjusting...

Benchmark versus Index in Mutual Fund Performance Evaluation

Vidal-García, Javier; Vidal, Marta - 2022

The adequate evaluation of mutual fund performance and of the fund managers’ ability to add value is an issue to which it has been given special attention in the recent financial literature. One of the traditional evaluation measures most commonly used is Carhart's alpha. However, one of the...

Generalized Performance Measures : Optimal Overweighing of Fees Relative to Sample Returns

Levy, Moshe - 2017

Performance measures such as alpha and the Sharpe ratio are typically based on sample returns net of fees. This implies the same weighing to sample returns and to fees. However, sample return parameters are noisy estimates of true parameters, while fees are known with certainty. Thus, intuition...

Predicting Returns Out of Sample : A Naïve Model Averaging Approach

Chen, Huafeng (Jason) - 2020

Prior literature finds that variables that can forecast market returns in sample do not beat historical averages in forecasting market returns out of sample. We propose a naïve model averaging (NMA) method, which produces mostly positive out-of-sample R2s for the variables that are significant...

Optimizing the Performance of Sample Mean-Variance Efficient Portfolios

Kirby, Chris - 2012

We propose a comprehensive empirical strategy for optimizing the out-of-sample performance of sample mean-variance efficient portfolios. After constructing a sample objective function that accounts for the impact of estimation risk, specification errors, and transaction costs on portfolio...
