In this article we test the weak form of the efficient market hypothesis for Central and Eastern Europe (CEE) equity markets for the period 1999–2009. To test weak-form efficiency in the markets, this study uses autocorrelation analysis runs test and variance ratio test. We find that...

In this paper, we propose several finite-sample specification tests for multivariate linear regressions (MLR) with applications to asset pricing models. We focus on departures from the assumption of i.i.d. errors assumption, at univariate and multivariate levels, with Gaussian and non-Gaussian...

In this paper we propose exact likelihood-based mean-variance efficiency tests of the market portfolio in the context of Capital Asset Pricing Model (CAPM), allowing for a wide class of error distributions which include normality as a special case. These tests are developed in the frame-work of...

This study measures the degree of short-horizon return predictability of 50 international equity markets and examines how its variation is related to the indicators of equity market development. Two multiple-horizon variance ratio tests are employed to measure the degree of return...

We compare the momentum strategies to “naive” uninformed strategies in Taiwan, Hong Kong, and Korea. The high participation of individual investors in these economies makes it an ideal setting to use the score function proposed by Banerjee and Hung (BH, 2011). As in BH we find that the...

Are financial markets efficient? There are multiple tests for answering this question. Forming a hypothesis and testing should be done before looking at the data, i.e. without data snooping. However, the parameters used in the tests of the efficient market hypothesis are often not decided...

This paper empirically investigates the impact of the Global financial crisis on the efficiency of four Central and Eastern European emerging unit-linked insurance markets, applying the automatic variance ratio (AVR) test of Kim (2009) and variance ratio tests using ranks and signs by Wright...

This study investigates another calendar anomaly the literature does not yet address – the week-of-the-year (WOY) effect. Using the weekly returns on the stock market indexes of 20 countries worldwide, for a period that ends in December 2010, the findings demonstrate that returns in Week 44,...
