In this book I present classical quantitative finance. The book is suitable for students on advanced undergraduate finance and derivatives courses, MBA courses, and graduate courses that are mainly taught, as opposed to ones that are based on research. The text is quite self-contained, with, I hope, helpful sidebars (‘Time Out’) covering the more mathematical aspects of the subject for those who feel a little bit uncomfortable. Little prior knowledge is assumed, other than basic calculus, even stochastic calculus is explained here in a simple, accessible way. By the end of the book you should know enough quantitative finance to understand most derivative contracts, to converse knowledgeably about.
