This paper studies the impact of contracted market makers by investigating the liquidity provider scheme in Sweden. The results show that the stocks become more liquid after the introduction of the contracted market makers. The liquidity improvement is explained by reduced order processing cost...

Is there an informational gain by training a Deep Reinforcement Learning agent for automated stock trading using other time series than the one to be traded? In this work, we implement a DRL algorithm in a solid framework within a model-free and actor-critic approach and learn it with 21 global...

A linear return generating model is introduced. This model is a generalization in discrete time of the differential equation describing dynamical systems in continuous time. The model is useful in its own right, as it provides a simplified, yet credible, quantitative description of the reality....

Political, economic and legal risks are among the causes of market inefficiency and the consequent under-development of financial markets. To further the understanding of the factors affecting market development, this study evaluates the Athens Stock Exchange (ASE). The Greek market provides a...

Extending the controversial findings from the relevant literature, the results from the quarterly transaction-based Nationwide indices from 1974 to 2009 provide further empirical evidence on the rejection of the weak-form version of efficiency in the U.K. housing market. In addition to...

This paper reports a wandering weekday effect: the pattern of day seasonality in stock market returns is not fixed, as assumed in the Monday or weekend effects, but changes over time. Analysing daily closing prices in eleven major stock markets during 1993–2007, our results show that the...

This paper is the first to present explicit empirical evidence that market inefficiency is multi-dimensional. Testing the Efficient Market Hypothesis (EMH) over 76 stock indices using 17 well accepted indicators (e.g. runs test), results show that most indices exhibit some type(s) of...

This paper provides evidence that currency spot prices are autocorrelated, which indicates that technical analysis in foreign exchange trading can and should take a leading role for analyzing expected exchange rate movements. The Augmented Dickey-Fuller test was used to test the Random Walk...

We examine investors' reactions to sharp price changes in seven equity markets of Gulf Cooperation Council (GCC) countries to uncover patters of price formation. We compare the price behavior and volatility of these markets within a 15-day window following the arrival of new information. We find...

The Asia-Pacific region's currency markets are generally efficient within-country when tested using the Johansen (1991, 1995) cointegration technique whereas market efficiency fails to hold when tested using Fama's (1984) conventional regression. Using the Pilbeam and Olmo (2011) model, we...
