One number defined trading on the Casablanca stock exchange today: +5.5% for Colas Maroc, the session’s top gainer at 77.0 MAD, even as the MASI index fell 0.24% to 16,934.59 points on Tuesday, October 20, 2026. In a market where 38 stocks declined, against 22 gainers and 21 unchanged, that move clearly set infrastructure apart as one of the few pockets of resilience.
The divergence matters. With Brent crude still elevated at $108.34 a barrel, despite a daily drop of 1.1%, and with the USD/MAD up 3.95% at 9.7997 while the EUR/MAD rose 3.76% to 10.996, Moroccan listed companies exposed to imported inputs, fuel costs and foreign-currency procurement are facing a tougher margin backdrop. Colas Maroc’s rally suggests the market is, at least for now, giving more weight to activity visibility in public works and infrastructure than to the immediate pressure from energy and FX.
