A simple introductory book to the world of finance, touching the basic concepts of investment and financing decisions, including: - Stocks, Bonds, and the main financial assets;- NPV, IRR and other investment criteria;- Risk, CAPM & behavioural finance. From the preface: "Sooner or later, you must have heard people around you telling: "I don't like finance and do not care about it!". This could happen frequently, but in my opinion it is like saying "I don't care about security", while a burglar is robbing your house. Finance does not simply mean making money, but also protecting what we have hardly worked for - thus making our whole life better. I strongly believe that a minimum knowledge of finance is essential for everyone and should not only be spread among an elite of university students.There is no need to wait for financial consultants to approach you, telling to invest your money into something: your whole life is an investment, and deciding not to invest is an investment choice as well. This book aims to give to all readers the fundamental principles of this broad subject, in order to make most financial decisions with an increased awareness."Niccolò Fanelli
