Financial Derivatives  are one of the most exciting and important course in finance. Financial derivatives such as forwards, futures, swaps, and options allow a risk manager to mitigate or even eliminate unwanted risks her company is facing, thereby allowing the company to focus on its comparative advantage. Financial derivatives allow investors to trade on future price movements with minimal upfront investments thereby making financial markets more liquid and efficient. Interest rate and currency swaps give a company a lot of flexibility when choosing to finance a project with debt.
