Popis: The study revisits the stock–oil nexus by examining the reactions of equity markets to oil price shocks at national and sectoral levels for Saudi Arabia in a time‐varying framework by employing the Markov switching EGARCH model developed by Henry (2009, Journal of Banking and Finance, 33, 405). Based on weekly data, the findings reveal that the behaviour of all stock markets switches between an expansion regime and a recession regime, with more persistence for the expansion state. Additionally, influential international events associated with stock market drops are clearly identified in the recession regime. Furthermore, there is evidence of asymmetric reactions of the equity index returns and the probabilities of transition from one state to another to oil price variations, with heterogeneous impacts across sectors and regimes. The stock markets are more sensitive to oil price decreases than to oil price increases. Although the evidence of relatively slight differences in some findings across weekdays, the study allows investors and policymakers to understand well the interactions of stock sector markets vis‐a‐vis the world oil market in a regime‐switching framework, in order to make the right decision as regards portfolio diversification and regulation of the stock markets.
