In this book I have tried to cover the fundamentals of investing, trading and speculating with case studies and real-life stories to help explain the context in a relatable way. Most of the case studies, stories and commentary are based on My experiences in the rough-and-tumble world of financial markets. Financial markets are basically comprised of different kinds of people and their varied way of thinking. One has to look into the psychology of human beings, as this is vital to understand when functioning in the financial markets. The most common psychological traits such as fear, greed, bias, emotion and overconfidence affect investment decisions, which in turn affect the traders and speculators.
