Cherry Picking The Diamonds From The Stock Market

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.

VERY good question, and I have the answer you’re looking for. Back in the mid-twentieth century, there was a professor at Columbia Business school named Benjamin Graham. He was considered (and still is) the best authority on investment ever, and founded the philosophy of "Value Investing." This is a type of investing where you find stocks that are cheap and safe relative to the company they are issued by. He taught Buffet everything he knew, which led to Buffett’s enormous success.
Graham wrote two very famous books. The first one you should read is "The Intelligent Investor". This is meant more for laymen or people not professionally investing. Next is his textbook "Security Analysis", which details who to analyze and pick stocks. This book is well over 700 pages, and is only necessary if you’re getting serious in the stock market.

Besides those two books and anything else Graham ever wrote or said, I’d say Buffett’s own books.
