Hi Sudheerr,
IVRCLINFRA, look for a break out above 350 which may have already happened today, and it is looking bullish. All time high in Jan 08 was over 600. These figures are NOT targets, they are simply prices that the stock reached in the past. If the company is good and continues to grow steadily there is no good reason why these prices will not be seen again. But that doesn't mean they will reach these highs again in the next couple of months. They might, but it is better to take a longer term perspective and think it is more reasonable over 3 years. If they reach sooner then all the better.
Please don't take anything I say as "advice". I'm simply giving you my opinion on your stocks based on the information I see today. If the information changes tomorrow my view will also change.
Try and start learning about charting and TA. You can start by searching the thread Beginners Guide and soon you will be able to see what I am seeing.
I use icharts.com. If you register with them you get free end of day charting which is all I am using.
Frankly, it seems you have picked some good stocks and got some good prices. Start learning how to manage them from today, and you will maximise your profits.
All the best.
