TTM EPS of Rs. 2.2 is discounted under 10 times.
The net profit of the company has increased from Rs. 5 crores in FY 2008 to Rs. 26 Crores in last 12 months ( 2 and half years)
I do not see any reason for you to think about time frames and targets.
Hold on to the stock tightly, SIP monthly and watch the quarterly numbers grow and share price increase.
Anyway, as it is a SIP call, I will update the same in mumbaibull.com SIP thread f something goes wrong.
