Egypt's heavyweight Commercial International Bank (CIB) rose by 1.33 per cent to LE30.46 per share.

Alembic HC upgraded GB Auto Group to "neutral" from "underweight", citing a recovery in Egypt's passenger car market, according to Reuters. GB Auto, the country's biggest listed automobile assembler, rose by 0.41 per cent to LE31.57 per share. The brokerage, which cut the target price on the stock by three per cent to LE33.5 per share, expects continued weakness in the company's commercial vehicles business. Commercial vehicles, which was on the cusp of recovery, has been affected by the unrest that culminated in president Hosni Mubarak's resignation on February 11, and will be the slowest to recover due to weak tourism and corporate demand, HC said. HC added GB's Iraqi joint venture GK Auto, which generated 37 per cent of its first-quarter revenue, would offset weakness in the Egyptian market.
