a r t i c l e i n f o We analyze the market efficiency of 25 commodity futures across various groups—metals, energies, soft commodities , grains and other agricultural commodities. To do so, we utilize the recently proposed Efficiency Index to find out that the most efficient among all of the analyzed commodities is heating oil, closely followed by WTI crude oil, cotton, wheat, and coffee. On t...

The efficiënt market hypothesis and related theories claim that it is impossible to predict future stock prices. Even so, empirical research has countered this claim by achieving better than random prediction performance. Using a model built from a combination of text mining and time series prediction, we provide further evidence to counter the efficient market hypothesis. We discuss the diffic...

This paper tests the hypothesis that the football betting market is efficient. Our statistical tests are stronger than those in previous studies, and we examine both NFL and college data over a sample period of fifteen years. Our statistical tests detect two specific biases in the NFL market and an unspecified bias in the college market. We examine the year-to-year consistency and magnitudes of...

Alternative strategies for predicting stock market volatility are examined. In out-of-sample forecasting experiments implied-volatility information, derived from contemporaneously observed option prices or history-based volatility predictors, such as GARCH models, are investigated, to determine if they are more appropriate for predicting future return volatility. Employing German DAX-index retu...

Random walk properties of equity prices influence return dynamics, and market efficiency is often considered an essential criterion in the assessment of the functionality of markets and the asset pricing process, which is of signi...

Artificial stock markets are models of financial markets used to study and understand market dynamics. Agent Based Artificial Stock Markets can be seen as any market model in which prices are formed endogenously as a result of participants’ interaction and in which the representation of participants varies from simple equations of forecast functions to intricate software components endowed with...
