Abstract
This paper investigates the impact of oil price changes on herding behaviour in the Gulf Cooperation Council (GCC) stock market. For this purpose, a sectoral analysis was employed. Based on a combination of the methodologies of Ulussever and Demirer (Cent Bank Rev 17:77-89, 2017) and Medhioub and Chaffai (Int J Financ Stud 7(65):1-11, 2019) and using daily prices for the five GCC sectors from 6 July 2014 to 31 December 2019, the results showed that the impact of changes in oil price movements on herding behaviour differs among sectors and subperiods. Further, we discovered that some sectors herd around the oil price returns during falling and that oil return dispersions have a dominant influence on some sectors during downward and/or upward periods.
