In financial economics, numerous theoretical models explain the relationship between investment risk and return in the capital market, one of the most common being the Capital Asset Pricing Model (CAPM). After reviewing the literature in this area, this study discusses the theoretical background...

Coherent measures of risk defined by the axioms of monotonicity, subadditivity, positive homogeneity, and translation invariance are recent tools in risk management to assess the amount of risk agents are exposed to. If they also satisfy law invariance and comonotonic additivity, then we get a...

This study aims to investigate the market timing strategy in different market conditions (i.e. up, down, normal and in-financial-crisis situation) in the emerging market of Pakistan over the period 1995 to 2015. Furthermore, this study tests the validity of the capital asset pricing model (CAPM)...

This paper extends the classic factor-based asset pricing model by including network linkages in linear factor models. We assume that the network linkages are exogenously provided. This extension of the model allows a better understanding of the causes of systematic risk and shows that (i)...

Se han analizado 6 grupos de variables en un intento de explicar el retorno futuro de las acciones utilizando el CAPM en España. Específicamente, se han realizado variadas simulaciones históricas y regresiones de corte transversal de los retornos de las acciones componentes de la muestra...

En el campo de las Finanzas, uno de los tópicos de investigación más importantes en los últimos años, ha sido la Valuación de Activos de Capital. Esta pretende determinar los factores que explican la tasa de retorno de tales activos. El Capital Asset Pricing Model (CAPM) y el Arbitrage...

We investigate the relationship between changing correlation structure of returns, security risk, and mean return. According to our results, securities that were highly correlated with the market-wide risk factors in the past are likely to have high systematic and idiosyncratic risk at present....

We use pre-World War I Brussels Stock Exchange (BSE) data to investigate the relation between average stock returns and market beta, size, momentum, dividend yield and total risk on the cross-section of stock returns. Based on portfolio sorts and Fama–MacBeth regressions, we find no...

We show that in the presence of non-zero pricing errors, the Fama–MacBeth (FM) cross-sectional regression test is very likely to either reject the Capital Asset Pricing Model (CAPM) when it (almost) holds or accept the model when it grossly fails. We investigate the case when pricing errors...

There is no consensus in the literature as to which model should be used to estimate the stock returns and the cost of capital in the emerging markets. The Capital Asset Pricing Model (CAPM) that is most often used for this purpose in the developed markets has a poor empirical record and is...
