Monday fade, Sunday jump? What a year of EGX daily returns actually shows Pend ran a calendar study on ~10 liquid names — EGX food, fertilizer, and chemicals plus ADIB UAE — using close-to-close daily % change from Jan 2025 through May 2026.

Long histories cover roughly 330 Sunday–Thursday sessions each no Friday EGX trading . Pooled day-of-week averages historical only — not a forecast : Monday ~−0.13% avg return, 43% win rate — the weakest day; Tuesday ~+0.20%; Wednesday ~+0.08% flat/choppy ; Thursday ~+0.44%, 56% wins; Sunday ~+0.52%, 52% wins — the strongest. Six of ten names had Sunday as their best average day; Monday was the worst for four. Overnight vs intraday matters: on Mondays, several names gapped up at the open vs the prior close but closed lower intraday — e.g. Juhayna averaged +0.19% overnight then −0.58% open→close. A weak-Monday read is often after the open, not blind at the bell. Sunday blends two moves: Thursday close → Sunday open multi-day gap plus the Sunday session itself. AMOC showed the largest Sunday effect in the set; ADIB leaned Sunday/Wednesday rather than the pure EGX food/fertilizer shape. Within the week, strength clustered at week start Sun and week end Thu ; Wednesday was the dullest mid-week slot.
