Investment Banking vs. Corporate Finance: An Overview
A generally-accepted distinction between corporate finance roles and investment banking roles is that a corporate finance professional deals with day-to-day financial operations and handles short- and long-term business goals, while an investment banker focuses on raising capital. An investment banker might also run private placements and conduct merger and acquisitions (M&A) deals.
It could also be said that investment banking roles are tasked with growing a company, while the corporate finance industry is employed in order to manage a company.
