Casino's shares rose by around 10 percent in early session trading on Friday.

Analysts at JP Morgan said any weakness in Casino's share price offered a good buying opportunity.

"We would, however, buy that weakness as the new situation should prove beneficial for them as it would accelerate the execution of its asset disposal plan in the coming months, with some of the overhang from Rallye disappearing, in the context of the very high short interest," wrote JP Morgan.
