The clearest move on Monday, May 4, 2026 came from MICRODATA, whose shares surged 10.0% to MAD 743.5, as Casablanca investors rotated back into mid- and small-cap names. The jump came as Brent crude climbed 6.0% to $114.65 a barrel, a global energy shock that quickly reshaped sector positioning across Moroccan equities.
