Any person, who undertakes investment banking activity, employed
by himself or an organisation which undertakes investment activity,
is an investment banker. Hence he can be self employed or can be
employed by an investment banking institution.
Investment bankers are those, who can meet the financial
requirement of any commercial or government organisation. Unlike a
commercial banker, the risks of the investment is normally borne by
the investor himself , and the investment bankers assist the
investors with their expertise.
