How do traders process and learn from market information, what trading strategies should they use, and how does learning affect the market? This paper proposes a learning model of an articial limit order market with asymmetric information to address these issues. Using a genetic algorithm as a...

Prediction (or information) markets are markets where participants trade contracts whose payoff depends on unknown future events. Studying prediction markets allows to avoid many problems, which arise in some artificially designed behavioral experiments investigating collective decision making...

We document that investors can actually profit from the contemporaneous link between earnings accuracy and recommendation profitability (Loh and Mian (2006)). Differentiating between 'able' and 'lucky' analysts we suggest an implementable, i.e. look-ahead bias free, trading strategy that yields...

In this paper we design a simple trading strategy to exploit the hypothesized distinct informational content of the arithmetic and geometric mean. The rejection of cointegration between the two stock market indicators supports this conjecture. The profits generated by this cheaply replicable...

This paper investigates the impact of the news announcement of the Lehman Brothers’ (LBs) bankruptcy on the performance of the New York Stock Exchange (NYSE) sectors and financial industries. Based on descriptive index level results, Bartram and Bodnar (2009) conclude that the reaction of all...

In this paper we propose Generalized Momentum Asset Allocation Model (GMAA). GMAA is a new approach to construct optimal portfolio and is based on close examination of asset’s returns distribution. GMAA tries to capture certain market phenomena and use information they contain as predictors...

One of the leading criticisms of the Efficient Market Hypothesis (EMH) is the presence of so-called 'anomalies', i.e. empirical evidence of abnormal behaviour of asset prices which is inconsistent with market efficiency. However, most studies do not take into account transaction costs. Their...

This paper provides some new empirical evidence on the weekend effect, one of the most recognized anomalies in financial markets. Two different methods are used: (i) a trading robot approach to examine whether or not there is such an anomaly giving rise to exploitable profit opportunities by...
