This document provides an introduction to speculative markets, derivatives, and financial engineering. It defines speculative markets as markets that deal in derivative securities to manage financial risk. Derivatives derive their value from underlying assets and are created through financial engineering. Financial engineering is designing innovative financial instruments and processes to provide customized solutions to firms' financial risk management problems, such as interest rate and currency risk. It involves creating new securities and organizations through applying advances in related technologies. Financial innovation meets demands for risk sharing and transfer and lowers transaction costs.
