Reliance Infrastructure will merge with Jai corp and end up co-developing the whole the Navi Mumbai Sez along the rewas port, international airport/rail network at Navi Mumbai. Reliance group (Mukesh Ambani) is directly not allowed to get into the power business due to conflict with Anil Ambani's Reliance Energy therefore power and infrastructure needs will be handled by jai corp for Mukesh Ambani promoted Navi Mumbai Sez.
Basically, Anand Jain has 10% stake in the whole Navi Mumbai Sez hence when the Sez is fully operational the 10% stake itself will be mind blowing along with the orders to manage the Sez.
Hence strongly recommend this stock even at this level - definitely will reach from 850 to 2000 in no time and for long term holders this stock is raw gold.
