This paper describes strategic behavior in a nonequilibrium model of asset pricing with heterogeneous sophistication. Both risk and return are increasing in the naïveté of investors in the market. Optimal investment involves considering the effect that naïve investors have on the market. Further, we derive a simple characterization of the asset price dynamics that results from an arbitrary comb...

where is the Poisson process which corresponds to the underlying asset t , t is the jump size of asset price return with log normal distribution and  t means that there is a jump the value of the process before the jump is used on the left-hand side of the formula. Moreover, in 2003, Eraker Johannes and Polson [3] extended Bate’s work by incorporating jumps in volatility and their model is giv...

As a result of economic pressures caused by deregulation, utilities are looking at new ways to approach the business of operating and maintaining their assets. In particular, one utility has taken a look at managing their substation assets as if they were stocks in a portfolio. Like financial managers who try to maximize return-on-investment for each asset in a client's portfolio, substation ma...

We study how stock return’s predictability and model uncertainty affect a rational buy-and-hold investor’s decision to allocate her wealth for different lengths of investment horizons in the UK market. We consider the FTSE All-Share Index as the risky asset, and the UK Treasury bill as the risk free asset in forming the investor’s portfolio. We identify the most powerful predictors of the stock...

In the context of the measurement of market risk, the random variable is taken as the rate of return of a financial asset. One may define the return in different ways, the two most common are arithmetic and geometric returns. The distinction between these two types of returns is not well understood. They are frequently assumed to be approximately equal. Moreover they both are assumed to be norm...

We consider a portfolio allocation problem for trend following (TF) strategies on multiple correlated assets. Under simplifying assumptions of a Gaussian market and linear TF strategies, we derive analytical formulas for the mean and variance of the portfolio return. We construct then the optimal portfolio thatmaximizes risk-adjusted return by accounting for inter-asset correlations. The dynami...

the purpose of this paper is to examine the impact of internal and external factors on the ratio of outstanding claims in those banks which are accepted in tehran stock exchange. for this purpose, we used the data obtained from 8 banks and credit institution active in the tehran stock exchange and using data regression panel.  the present survey was examined over the period 2011 till 2015. the ...

Financial decision making involves uncertainty and consequently risk. It is well known that asset return forecasts and risk estimates are inherently inaccurate. The inaccuracy in forecasting and estimation can be addressed through the specification of rival scenarios. In this paper, we extend the multi-period mean-variance portfolio optimization and asset liability management problems to the ro...

This paper presents an optimization approach to analyze the problems of portfolio selection for longterm investments, taking into consideration the specific target replacement ratio for defined-contribution (DC) pension scheme; the purpose is to generate an effective multi-period asset allocation that reaches an amount matching the target liability at retirement date and reduce the downside ris...
