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...

Long-short anomaly returns are strongly related to the day of the week. Anomalies for which the speculative leg is the short (long) leg experience the highest (lowest) returns on Monday. The opposite pattern is observed on Fridays. The effects are large; Monday (Friday) alone accounts for over...

This paper analyzes market efficiency (EMH) with the day-of-the-week effect and the changes that might appear after the outbreak of the COVID-19 pandemic, based on the example of the OMX Exchange and its indices. Before the pandemic, only the OMX Baltic All‑share index was efficient; during...

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 stock...

This paper examines the presence of the day-of-the-week effect in the Italian stock market index (MIB) sub-sectoral returns. The study, by using GARCH-M (1,1) models, did not find evidence of the day-of-the-week effect in mean equations, while some evidence was present in variance equations. The...

This paper examines the efficiency in pricing securities as well as the relation between exchange rate and dynamics of equity returns in a number of emerging stock markets from Africa and Asia,. This study utilizes methodologies based on Single variance ratio test of Lo and Mackinlay (1988),...

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...

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...
