Vitaliy Katsenelson is the author of Active Value Investing and he also runs a blog called Contrarian Edge. His content is clear and always worth a read.
I just wanted to highlight one of his posts and report analyzing AMEX. Other companies he has looked at include Exxon, Supervalu and Jos A Bank.
It is dated Nov 12, but he lays out his reasoning in a way that anyone can understand and will benefit anyone trying to expand their circle of competence to the financial sector.
