The Stock Selection Guide has been used by millions of investors over the past forty-five years, and has proven to be a consistent and valuable tool in building successful stock portfolios.

This short tutorial does not attempt to provide an in-depth review of the Stock Selection Guide, but an introduction to a method of fundamental analysis that can be used by any individual investor interested in building a long-term portfolio of growth stocks.
