Investment bankers must conduct a wide range of jobs and tasks as part of their daily responsibilities. They must help businesses, organisations, and other entities raise public or private cash via stock or debt issues. They also create extensive financial models to examine and assist in transactions related to mergers and acquisitions as well as financial planning and analysis activities. Investment bankers use transaction comparisons, discounted cash flow, and leveraged buyout approaches to undertake business valuation evaluations. In order to find new clients and bring in new business, they also perform company and industry research, too.
