Dear, sateshwar,
Wipro, Infosys and Dr reddy sound good to me if we r talking about the stocks traded at NYSE only. Reason, appreciation of Rupee v/s $ seems to be limited. Whenever the direction changes, may be at around 39.5 or so, these firms r going to benefit. Seeing their track records these firms will sustain and keep giving good returns even if the Rupee apreciates further. Do'nt buy in bulk, keep accumulating on dips, remain invested for long.You will get good returns, that is what I feel and can reccomend to you with whatever bit I know.
good luck.
