The book is concerned with the theory of portfolios, as well as with investing in assets and securities and offers a general introduction, rather than a toolbox for making money. It will help its readers to better understand investing. The book is structured in two parts. Part I introduces the student into fundamental principles of portfolio theory and investment analysis, such as the Markowitz portfolio selection approach, factor models, basic evaluation techniques and portfolio management. Part II extends the material to more advanced topics and focuses on inefficient markets, including topics including technical analysis and momentum effects, behavioural finance, bubbles and herding, portfolio management in inefficient markets and market microstructure. followed by an appendix consisting of primers to some econometric approaches.
