Episode Details

Over the last 8 weeks Paul, Chris and Daryl have produced a series of podcasts and videos on 8 of the most important investment decisions investors make.  Along with these podcasts and videos Paul and Rich have written Marketwatch articles on the same topics.  As a part of the discussion of these important decisions Daryl has updated over 200 tables of hypothetical returns that are used to support the recommended conclusions.
