This textbook rethinks derivatives in a structured manner. This is done from the perspective of financial modeling, whereby the central issues from the financial economy are holistically mapped and resolved with the help of Microsoft Excel. The guideline of the book is an integrated case study, which is divided into two parts. The first part deals with the basics and the valuation of options and futures. In the second part, the individual option strategies are examined step by step in separate course units. The analysis ends - figuratively speaking - in a cockpit of sorts, where the reader controls the possible strategies in Excel. The book is aimed at students of business administration with a focus on finance.
