When stocks pay dividends they are of two kinds:
1. Qualified which is eligible for the 15% maximum tax rate. (Eligible not guaranteed as there are other factors.)
2. Non-qualified which which is taxed at your normal tax rate.
Without knowing the context of the footnote my best guess is that is what it's referring to.
Qualified has meaning in the context of taxes. Search form 1040 and/or instructions for same.
You need to clarify exactly what you are looking at. "Stocks" is a vague term.
when one looks at their stocks some will have a footnote "Qualified" ? DOes this have something to do with the stock itself or taxes?
