Abstract: This paper analyses price gaps in financial markets also known as trading, opening, common, stock, morning gaps – all these terms being used to indicate that the current day’s opening price is not the same as the previous day’s closing price. To test for the presence of such an anomaly in price dynamics stock, FOREX and commodity market daily data are used. The sample period goes from 2000 to 2015. Applying a variety of statistical tests we test six different hypotheses and are able to show that in most cases the observed price behaviour is not inconsistent with market efficiency, the exception being the FOREX: in this case a trading strategy based on exploiting the observed anomaly can generate abnormal profits.
