In the multiscaling approach, a time series is decomposed into different time horizons referred to as timescales. In this article, we investigate the risk-return relationship in a downside framework using timescales. Two measures of downside risk; downside beta and downside co-skewness are...

The finite sample performance of the Wald, GMM and Likelihood Ratio (LR) tests of multivariate asset pricing tests have been investigated in several studies on the US financial markets. This paper extends this analysis in two important ways. Firstly, considering the fact that the Wald test is...

The CAPM as the benchmark asset pricing model generally performs poorly in both developed and emerging markets. We investigate whether allowing the model parameters to vary improves the performance of the CAPM and the Fama-French model. Conditional asset pricing models scaled by conditional...

For emerging market returns there is strong evidence that the departure from normality is primarily driven by kurtosis and not skewness. This paper investigates the empirical validity of a return generating process that includes quadratic and cubic market returns as factors of pricing for an...

This paper tests and compares the CAPM of Black (1972) and the Mean Lower Partial Moment (MLPM) Capital Asset Pricing Model of Bawa and Lindenberg (1977) and Harlow and Rao (1989) in the context of emerging markets. It is well known that returns in emerging markets are non-normal and have...

This paper investigates the association between portfolio returns and higher-order systematic co-moments at different timescales obtained through wavelet multi-scaling, a technique that decomposes a given return series into timescales enabling investigation at different return intervals. In...
