There are of course many different specialties and fields under the management banner, such as the analyst for a major mutual fund group who must forecast future earnings and analyze portfolios. There the is bank manager of a retail branch who must create new accounts and originate loans; or perhaps you may sell securities for Merrill Lynch, or study emerging markets in Asia to see where the company may choose to invest its money, all performed under rules and statutory laws and regulations as well as unwritten codes of conduct created for everyone's general best interest. Clearly, there is enough flexibility in the financial world to create an setting for possible fraud and deception, therefore these codes are in place and reputation is very important to company viability and marketability.
In the larger companies, many of the most important decisions rests in fact not with the managers but with the executive officers or board of directors, especially regarding the largest outlays of capital expenditures, or the issuing of stock options or dividends. The manager, though, unlike the accountant, can also become involved in product development, marketing, and other projects as they can be inextricably interwoven with the budgeting process and therefore be called upon to work closely with teams from other parts of the company. Managers also must understand the financial markets in general, for in order to increase firm value many critical investment decisions are made in capital budgeting, in bank borrowing, or other investments. The function of these managers continues to grow and diversify with time.
