The day’s clearest contrast on the Casablanca stock exchange today came down to one number: AGMA jumped 5.6% to MAD 7,250 while the MASI index fell 0.83% to 18,113.11 points on Wednesday, May 20, 2026. In a session where 45 stocks declined against just 17 gainers, AGMA’s rise stood out as a reminder that selected mid-caps can still break away from a market weighed down by banks and industrial names.
That divergence matters. The MASI 20 lost 1.08% on the day and is now down 12.08% year to date, a much steeper drop than the broader MASI’s -3.89%. In other words, large caps remain the main source of pressure in Casablanca, while smaller names, less exposed to institutional de-risking, are occasionally finding room to outperform.
