Need foolish help,>>

Investments in the Foolish Four are made on specific dates based on a 12-month or 18-month cycle. Monthly additions are not advisable. For further information on the topic, head over to the Dow area of Fooldom ( http://www.fool.com/ddow/DDExplained.htm ) where you can obtain additional explanations of this investing method.
