A grand book, but far, far, far too much reference to Company REFS. I would prefer to spend the seven hundred pounds annual fee on buying good stocks. He gives the impression that without Company REFS, you've NO hope of choosing the winners by his method outlined in this book. Would have prefered the first Zulu Principle, as you can make the calculations from the Annual Reports. By all means it's a good method, but come on Jim, cut out the Company REFS stuff and help us to pick winners by this method by relating to the Annual Report. Be warned as well: many Fools on this site thinks the Slater bubble has burst. Think before trying this method!
