I will not recommend forgetting stocks for 10 years at one stretch. A coffee can portfolio is one which allows you to forget about the stocks for a long time!
‘Ideas’ are not just one time. Keep checking this atleast once a year (if not quarterly) for the following:
- Is the management integrity in tact?
- Sales growth and profit growth
- Return on equity
- Is the valuation expensive or cheap?
- Industry outlook
With this go ahead and screen your stocks. For specific names, do consult a SEBI Registered Investment Advisor or a certified professional. Do not rely on ‘market tips’.
