I am holding this stock right from 180 to 44 to now around 172...
It looks good to reach 200 in a couple of months (if no major surprises).
IDFC is looking to be a financial conglomerate. See Rajiv Lall`s interview in forbes magazine - quite positive (although he is advertising his company :-)
If Rajiv Lall is successful in getting a banking license, 500-600 is easily achievable in 2 years time frame.
