We have updated the online tutorial originally by Doug Gerlach that will help you understand SIG's analysis.

Special Note: Better Investing blocked automated access to their stock data feed by the Stock Investment Guide. You will still be able to download data files with your web browser and open them in SIG3. Meanwhile, we are working on alternatives. One alternate data source that is fully compatible with SIG is Stock Investor Pro by AAII. Read more about this at:
