RIYADH: Saudi stocks slightly regained momentum on Sunday, lifted by a rebound in crude prices at the end of last week. Oil prices rose about 4 percent on Friday after dropping to a seven-month low earlier in the week, supported by threatened cuts to supply. The Kingdom’s main index TASI advanced 0.9 percent to end at 11,940 on Sunday, while Nomu added 1.5 percent to 20,737.
