This paper investigates the performance of efficient portfolios in a financial market with heterogeneous investors including rational traders, noise traders, and chartists. A generalization of the security market line result states that, regardless of the diversity of beliefs, the portfolios of rational investors with mean-variance preferences are mean-variance efficient in the sense of classic...

Portfolio asset management must minimize risk exposure for the investor. Measuring performance of any instrument can be done by looking at risk-reward. Observe stock listed in BUMN 20 Index with measurement analytical tools like Sharpe ratio, Treynor Ratio, and Sortino ratio. This study is descriptive quantitative research as this aims to explain how ratio between 2018 2021. All population focu...

The fund manager always pronounces “the high returns from hedge fund are along with low risk. Is the performance of hedge fund manager really good? In this study, the market-timing ability and performance consistency on hedge fund manager are tested. The Sharpe ratio was employed to implement the consistency of performance for mutual fund in the previous literature. Due to the non-normally dist...

Optimal asset allocation well-fitting the investors goals is a pressing challenge in risk management. In spite of Sharpe ratio, Sortino-Satchell, Generalized Rachev and Farinelli-Tibiletti ratios are new parameter-dependent performance ratios able to suit the investor risk profile. Five investor prototypes are studied and fifteen tailormade optimal asset paths are traced over a rolling twelve m...

In this paper I derive a risk-adjusted measure of portfolio performance (now known as "Jensen's Alpha") that estimates how much a manager's forecasting ability contributes to the fund's returns. The measure is based on the theory of the pricing of capital assets by Sharpe (1964), Lintner (1965a) and Treynor (Undated). I apply the measure to estimate the predictive ability of 115 mutual fund man...

SHARPE is a well known package in the field of reliability and performability, used in universities as well as in companies. A modeler who is familiar with many different kinds of models, can easily choose models that best suit a particular system and the kind of measure that is needed at each stage of the design. It is also possible to use different kinds of models hierarchically for different...

In this paper, we establish a new coherent risk measure on Lp, which refer to as the monotone mean Lp-deviation measure. Then, related properties are discussed. Furthermore, from perspective of acceptance set, discuss relationship between and Sharpe ratio Finally, extend multivariate setting.

While many trading strategies are based on price prediction, traders in financial markets are typically interested in optimizing risk-adjusted performance such as the Sharpe Ratio, rather than the price predictions themselves. This paper introduces an approach which generates a nonlinear strategy that explicitly maximizes the Sharpe Ratio. It is expressed as a neural network model whose output ...

Greed plays an important in the fluctuations of stock prices because investors want profits irrespective risk taken by them.
