Where can I learn all the smallest nuances of how warren buffett picks stocks,?
and all the technicalities of analysing and filtering through balance sheets for relevant information? Actually, I have read many books on Buffett, but he hasn't set out the exact tools and techniques that he uses for value investing, in detail. Where can I learn these tools and techniques in detail? I am willing to go anywhere to learn these techniques. Please suggest.

Investing well is an art and not a science. Perhaps Warren Buffett doesn't have exact tools and techniques for value investing. And that might be why he hasn't mentioned them in his books. He probably uses his judgment a lot.

Relying on formulas and techniques is what the banking industry did until the present credit crisis. And we all know what happened to them as a result of that.

Formulas and the techniques can never be a good substitute for common-sense judgment.
