The kingdom's main index reversed course to fall 0.4 percent, a day after breaching its 200-day average for the first time in three weeks.
Middle East funds have become more wary, but not outright bearish, toward Saudi Arabia's stock market because of concern over the fallout from the killing of Jamal Khashoggi, a monthly Reuters poll showed on Wednesday.
Foreign investors, including those from other Gulf states, were net sellers of Saudi equities for most of this month, partly because of fear that Khashoggi's death could damage Saudi ties with the West and conceivably lead to economic sanctions.
But the poll of 13 Middle Eastern fund managers, conducted over the past week, suggested most funds do not intend to continue selling.
