Large institutional investors own an increasing share of equity markets in the U.S. The implications of this development for financial markets are still unclear. The paper presents novel empirical evidence that ownership by large institutions predicts higher volatility and greater noise in stock...

The study is carried out with the objective of testing the efficient market hypothesis (EMH) at the semistrong form level. As such, the study employs two publicly available data variables – the exchange rate (RM/USD) and short-term interest rate as proxied by the overnight policy rate (OPR)....

Aim/purpose - The aim of this paper is to verify whether extremely high values of market value ratios are the symptoms of informational inefficiency of the market in a weak form. The authors intend to examine whether these phenomena co-occur with each other. Design/methodology/approach -...

The flow of information between futures and spot prices may vary over time, in particular during periods of stress. This article analyses the information content of the Bund Future and German government bonds during 1998 and test whether it is constant over time. The use of high-frequency data...

Climate science finds that the trend towards higher global temperatures exacerbates the risks of droughts. We investigate whether the prices of food stocks efficiently discount these risks. Using data from thirty-one countries with publicly-traded food companies, we rank these countries each...

This paper presents evidence suggestive of a conditional violation of weak-form market efficiency. Evidence suggests that the AR coefficient monotonically decreases along the return distribution, for each value and equal weighted market indices. These results suggest that the AR coefficient is...

Two alternative versions of the efficient market model are compared, a Bayesian version and an orthodox version. The Bayesian version is usually used to define an efficient market models, where markets make optimum use of all available information. However, the orthodox version is usually used...

Observed by more than 1.5 billion Muslims, Ramadan is one of the most celebrated religious rituals in the world. We investigate stock returns during Ramadan for 14 predominantly Muslim countries over the years 1989-2007. The results show that stock returns during Ramadan are significantly higher...

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...

A popular interpretation of the Rational Expectations/Efficient Markets hypothesis states that, if the hypothesis holds, then market valuations must follow a random walk. This postulate has frequently been criticized on the basis of empirical evidence. Yet the assertion itself incurs what we...
