At a time when the practices and investment techniques of Wall Street analysts are being questioned widely for being biased and not thorough, Robert Hagstrom teaches how investment professionals and personal investors can take investment decisions into their hands successfully by applying the methods of some of the world's most famous detectives, including Sir Arthur Conan Doyle's Sherlock Holmes, Edgar Allan Poe's Auguste Dupin, G.K. Chesterton's Father Brown and Agatha Christie's Hercule Poirot. Hagstrom advocates that the careful mental process that these great analytical detectives use to evaluate evidence and reach a logical conclusion can be used to evaluate potential investments. Each detective has his own set of analytical skills that can be matched with certain types of investors. Hagstrom emphasizes Dupin's strong deductive reasoning, the encyclopedic knowledge of the facts such as that of Sherlock Holmes, and the intuitive insights of Father Brown. There is something for everyone, and Hagstrom teaches investors how to reach within themselves and learn to develop their own set of skills, logic, perceptions similar to those of the detectives rather than relying on published analyst reports, financial statements and newspapers.
