The present book deals with the topic of Value Investing. This economic investment strategy takes into account qualitative and quantitative criteria for evaluating a stock. The qualitative characteristics are objectively assessed based on information and are incorporated into the valuation process. The quantitative company analysis focuses on the balance sheet of a stock. In this context, the value investor specifically looks for fundamentally undervalued stocks in order to achieve an excess return through their purchase. The art of value investing lies in accurately assessing the valuation of these two components to generate higher returns. The goal of the method is to determine the so-called intrinsic value of a stock and compare it with its market price. Weighing the qualitative assessment, the investor ultimately determines whether the stock is undervalued.
