✦ Synopsis

This paper presents new empirical evidence of the effect of periodic market closures in financial markets which is not available in the literature yet. In particular, employing closing and opening prices, we have found that the intensity of the long-range dependence phenomena presented in this market depends on the time of the day that this phenomena is measured. This kind of pattern seems to be related to trading performed by different types of investors and the flow of information over the day.
