what to do if a stock slumps just after u bought it?

To worry if

1) buying is based on feel

2) buying is based on hearsay

3) emergency funds are used

4) no prior homework is done

5) amount constitutes a large part of entire wealth

6) no dividends in sight

7) sudden change in company fundamentals(though rare)

8) buying using ah long or borrowed money

Not to worry if

1) buying based on sound analysis

2) adequate diversification

3) reliable dividends

4) cash back up

5) emergency funds intact

6) plan in place even before purchase

My 2 cents worth....

Thanks for reading!
