It is surprising to think that there was a time when people did not use money. In the moneyless state, people directly exchanged what they had in surplus, to procure what they wanted. The word 'public' means all persons national as well as foreign. It also includes all institutions and companies, national and foreign, except the central bank of the country and those institutions that provide demand deposits. The central bank of a country manages the money supply according to objectives laid down by its government. Investment in a finance company, however, is one of the riskier options. A growing trend in the financial markets is the rise of fund management companies. They do not raise money themselves but manage funds of other institutions according to their requirement. They employ finance professionals who take over the management of the assets of others and convert them into customised portfolios with desired properties.
