Dr. Al-Assaf went on to say that the decision also took into account the desire of foreign investors to participate in the Saudi stock market, and this will be done through a controlled mechanism that will guarantee the market's equilibrium. The Saudi stock market is the largest in the Middle East in terms of value, at around just over U.S. $ 50 billion. Saudi banks currently operate 119 investment portfolios, few of which specialize in local stocks.
