The capital asset pricing model (CAPM) is often based on the Gaussianity or normality assumption. However, such an assumption frequently violated in practical situations. In this paper, we introduce symmetric CAPM considering distributions with lighter heavier tails than normal distribution. These are and belong to family of elliptical distributions. We pay special attention members related nor...

The alpha is one of the most used terms in finance. Yet, the alpha is mystical since it has no theory. It is, for example, in contradiction to the standard CAPM with homogenous beliefs. The purpose of this paper is to show that the alpha naturally arises in a financial market equilibrium when the CAPM is extended to heterogenous beliefs. We show that the hunt for alpha-opportunities is a zero-s...

In this paper we test for the inclusion of the bid-ask spread in the consumption CAPM, in the UK stock market over the time period of 1980-2000. Two econometric models are used; first, Fisher’s (1994) asset pricing model is estimated by GMM, and secondly, the VAR approach proposed by Campbell and Shiller is extended to include the bid-ask spread. Overall the statistical tests are unable to reje...

This paper provides an alternate method of evaluating portfolio performance of stock pricing models. We apply Pitman Closeness Criterion to compare the accuracy of three popular pricing models. This comparison is used to assess which, if any, model outperforms the others. In assessing model performance over a long period of time, we find that the Fama-French three-factor model and the Carhart f...

In this paper the author formulates and tests an international intertemporal capital asset pricing model in the presence of deviations from purchasing power parity (II-CAPM [PPP]). He finds evidence in favor of at least mild segmentation of international equity markets in which only global market risk appears to be priced. When using the Hansen & Jagannathan (1991, 1997) variance bounds and dis...

We extend the Consumption-based CAPM (C-CAPM) model for representative agents with different risk attitudes. We introduce the concept of expectation dependence and show that for a risk averse representative agent, it is the first-degree expectation dependence rather than the covariance that determines C-CAPM’s riskiness. We extend the assumption of risk aversion to prudence and provide a weaker...

We report on six large-scale financial markets experiments that were designed to test two of the most basic propositions of modern asset pricing theory, namely, that the interaction between risk averse agents in a competitive market leads to equilibration, and that, in equilibrium, risk premia are solely determined by covariance with aggregate risk. We designed the experiments within the framew...

Testing CAPM with a Large Number of Assets This paper is concerned with testing the time series implications of the capital asset pricing model (CAPM) due to Sharpe (1964) and Lintner (1965), when the number of securities, N, is large relative to the time dimension, T, of the return series. In the case of cross-sectionally correlated errors, using a threshold estimator of the average squares of...

The negative CAPM alphas of high-beta and high-variance stocks are attributable to an unaccounted factor in the CAPM. We use eight seemingly unrelated anomalies construct a composite spirit optimal orthogonal portfolio (FOP). Accounting for FOP re-establishes positive relation between beta average returns time series regressions as well cross-sectional explains stocks. To analyze economic drive...
