Hi Byculla,
Lots of people say they use Warren Buffett's Value Investing strategies, but not many do. VSS uses Buffett's formula taken directly from, "Buffettology," by Mary Buffett and David Clark.
They poured over Buffett's writings and explained what he does. I'd definitely put that book on your reading list if you're interesting in Value Investing.
VSS adds the accrual ratio from Richard Sloan's research and it uses Pat Dorsey's (Morningstar's Director of Stock Analysis) formula for economic moat strength (along with one Buffett's criterion).
I have not seen another software package come as close to pure Buffett as VSS does.
I'm not a big fan of TA, but there are certainly a few indicators that make sense. However I feel most of it is just multi-layered curve fitting.
I'm not sure what you mean by, "AAI." Do you mean Automatic Investor or AAII.com?
As always, feel free to post your questions here.
