An investment bank is a bank or a division of the bank, which brings together all the activities of advisory, intermediation and enforcement relating to the operations of said high stock (IPO, debt issuance, merger/acquisition) of large corporate clients (companies, investors, but also states) (Rosenbaum, 2009). Sometimes investment banking can be differentiated from corporate banking by setting the market activities and the corporate finance. However the term bank financing and investment (BFI), which includes both activities, is becoming widespread. The different things, that investment banks do, have been mentioned here. They issue securities for IPOs, capital gains, OPA, OPE, etc. They also deal with mergers and acquisitions. They organize the markets based on financial tools. They also do financial engineering which involves complicated processes related to finances. They make investments in the equity of companies for their clients. They organize pool financing for projects and also provide stock trading facilities (Harwood, 2006). All these things are needed to be done quite carefully as a lot of money are involved in these tasks (Stephen, 2009). A single mistake can bring a lot of trouble for the clients. That is the main reason why the investment bankers are paid large salaries and bonuses. Bonuses are paid to them mainly because to motivate them in their work. It is not possible for people to work for a long time especially in this field. They need some kinds of recreation.
