A master’s degree in finance broadly teaches three things – corporate finance, asset management, and financial markets. All these are important for a company. A good financial management leads a company to use its funds properly and facilitate a smooth function. Asset management is the planning of how to park their finances for better use later and study of financial markets allows the company to know about interest rates etc.
A masters course also teaches about other corporate affairs like further investment, how to acquire a new company and how to provide funds for that. It also teaches the macroeconomic level management.
