In an intensifying competition banks are forced to develop and implement enterprise wide integrated risk-return management systems. Financial risks have to be limited and managed from a bank wide portfolio perspective. Risk management rules must be accomplished from internal and regulatory points of view. Expected returns need to be maximized subject to these constraints, leading to a generaliz...

I demonstrate that with the market return determined by equilibrium returns of CAPM, expected an asset are affected risks all assets jointly. Another implication is range feasible will be limited and dependent on distribution weights in portfolio. A large well diversified no dominating only zero while a dominated small number risk-free rate. In limiting case atomistic assets, we recover propert...

Behavioral finance and classical finance based on utility maximization appear to be mutually exclusive schools of thought. Despite the fundamental difference, we show that behavioral finance also has a linear relation between risk and return. This relation is obtained without the assumptions of market equilibrium, rational expectations, a specific utility function and the market portfolio. In t...

credit allocation through the usage of portfolio optimization mainly seeks tomaximize return and minimize the risk of the portfolio; but there are other importantissues including sustainable development which is important for government/publicsectors. this paper presents a novel credit allocation approach based on portfoliooptimization and investigates the effects of selected indicators of sust...

In this research, a novel approach is developed to predict stocks return and risks. In this three stage method, through a comprehensive investigation all possible features which can be effective on stocks risk and return are identified. Then, in the next stage risk and return are predicted by applying data mining techniques for the given features. Finally, we develop a hybrid algorithm, on the ...

This paper develops a search-theoretic model of the cross-sectional distribution of asset returns, abstracting from risk premia and focusing exclusively on liquidity. I derive a float-adjusted return model (FARM), explaining the pricing of liquidity with a simple linear formula: In equilibrium, the liquidity spread of an asset is proportional to the inverse of its free float, the portion of its...

To reconcile the disconnect between survey expectations of stock returns and rational expectations, researchers have hypothesized that participants may confound beliefs preferences by (i) reporting risk-neutral forecasts future returns; or (ii) pessimistically-tilted reflecting ambiguity aversion robustness concerns. We find these hypotheses are strongly rejected data, albeit for different reas...

In investing, investors will try to limit all the risks in managing their investments. Investor strategies minimize investment risk are diversification by forming portfolios, one of which is Mean-Variance without risk-free assets. The calculation results show composition optimum portfolio return for each stock that forms portfolio. Optimum obtained with wT = (0.39853, 0.25519, 0.13644, 0.09788,...

Can the usage of a risky numeraire with a greater than risk free expected return reduce the capital requirements in a solvency test? I will show that this is not the case. In fact, under a reasonable technical condition, there exists no optimal numeraire which yields smaller capital requirements than any other numeraire. 1 Statement and Proof of the Result Can the usage of a risky numeraire wit...
