Mukesh Ambani's Reliance Industries [Get Quote], which carries high weightage in the Sensex, soared to an all-time high of Rs 637.10, a rise of Rs 36.25 or 6.03 per cent today.

On the future prospects of Reliance companies, Kampani said, "Earlier there was only one horse (Dhirubhai). Now you have two -- Mukesh and Anil. Both the brothers are hard workers, they have vision, they can add value."

As per the settlement announced by late Dhirubhai's widow Kokilaben, Mukesh gets to retain management control of RIL and IPCL, while Anil gets REL, Reliance Capital [Get Quote] and Reliance Infocomm.
