This is my experience friend, before buy stock determine the both target price (up & down), and if it touches that level dispose it, hold it only if you are certain something.
These are few real examples
I bought 1,000 CDIC with approximate cost of 200/= and when it went to 300 plus i sold it later it went to 700 plus or something.
Same thing happen to me with the CFLB, after i disposed it went like this.
Only stock i hold against policy was LLUB i bought at 170/= level before split and hold for considerable period of time and dispose between 360 to 370. Now am closely watching this again and if the suitable price come i ll buy again.
