Abstract
The chapter introduces the multi-period dynamic securities market model, an extension of the two-period model, which served as the main framework in Part I of the book. It states a multi-period version of the no-arbitrage hypothesis and discusses the concepts of market scenarios (histories), contingent portfolios, trading strategies, self-financing trading strategies, contingent claims and derivative securities. It presents one of the highlights of Mathematical Finance: the no-arbitrage pricing principle for contingent claims. The chapter concludes with defining the net present value (NPV) of a trading strategy and establishing an equivalent version of the no-arbitrage hypothesis stated in terms of the NPV.
