The Egyptian bourse said in a statement that “the main change in the mechanism is in evaluating shares by trading volumes on a monthly basis, rather than on a bi-annual basis.” A stock will be included in the EGX30 based on the number of months of it being amongst the top 30 shares by volume traded during a six-month evaluation period (new stocks will be evaluated from when they start trading until the end of the evaluation period). The number of days required for the stock to remain trading for inclusion was raised to 78 instead of 60 during the evaluation period.
