A Saudi broker monitors the stock market at the Arab National Bank in the Saudi capital Riyadh on December 11, 2019. Gulf markets were down slightly on Sunday, providing an early indication of investor reaction to Iran's unprecedented attack on Israeli territory. Saudi Arabia's benchmark stock index fell 1.8% in early trading while the main Qatari index was down 1.6%, with Gulf lender QNB leading losses. Iran's retaliatory drone and missile attack in response to a suspected Israeli air strike raises the threat of wider regional conflict. Israel reported modest damage, but the key for investors will be how the conflict unfolds from here.
