Been a while since I saw the book, I think it's conventional AIM.
Biggest caveat is how the author selects stocks. He looks for stocks at yearly lows. That's what I did as a novice, it was a disaster. While there are bargains in that group, there is even more trash. There's a reason for most of those stocks to be selling at lows. If anyone wants to follow Weber's method, do a lot of research, before beginning a program. AIM will not help you, if you're investing in a failing company.
