It is known that the Capital Asset Pricing Model (CAPM) provides an expression which relates the expected return of an asset to its systematic risk. In a decision making problem involving financial data however, we have to take in account the uncertainty given by the imprecision and the incompleteness of the information. Uncertainty in the data may be treated by considering, rather than a singl...

the capital asset pricing model (capm) is an equilibrium model for explaining the relationship between risk and returns of individual assets. in other words, the capm shows that how assets are priced according to their risk. capm is based on the assumption that investors is finding the efficient portfolio act in such a way that the efficient portfolio theory explains and their choices of the po...

Airlines are the business of transporting passengers in which the safety and risk have always been important. We use the fuzzy CAPM and fuzzy ICAPM models to investigate the underwriting systematic risk and profit margin of aviation transportation, in which the parameters of membership function are the asymmetric triangular fuzzy number. We calculate the underwriting systematic risk and profit ...

In strict terms, the Capital Asset Pricing Model applies only to marketed assets, but the CAPM is frequently used to assign prices to nonmarketed assets as well. The Correlation Pricing Formula (CPF) is similar in form to the CAPM, and gives the same result. However, the CPF expresses the price of a nonmarketed asset in terms of a priced asset that is most correlated with the nonmarketed asset,...

This paper develops and estimates a heteroskedastic variant of Campbell s [Campbell, J., 1993. Intertemporal asset pricing without consumption data. American Economic Review 83, 487–512] ICAPM, in which risk factors include a stock market return and variables forecasting stock market returns or variance. Our main innovation is the use of a new set of predictive variables, which not only have su...
