How to create and manage portfolio?

Be a Smart Investor

Rules:-

1. Don't be fully invested:- Maintain cash reserve to making average when market fall.                                    
2. Don't invest in only one stock:- Company is not immortal. Only invest 10% amount in one stock                                                                                                                                                 
3. Don't invest more than 25% in one sector:- Diversify on the basis of  sector also. Sometimes sector goes in downtrend for three to four years.                                                                                             
4. If market rising at that time you are buying and when fall that time you selling then you are doing wrong.(Buy at low and Sell at High)                                                                                      
5. If your confidence rise and fall with price movement of stock then you are invest with emotions. Your confidence must attach with company's fundamentals not a price movement.

Picking good stocks and becoming good investor are both different things.
