Some more details

Who are they, these speculators? The analysis shows that in the role of main speculators operating at the market, are, as not paradoxically, foremost institutional investors. It is possible to select among them – first of all – official state establishments and, in the second turn, private financial and other institutes. So, in obedience to the domination of "group ten", state investors in Europe and Japan hold of the about 20% assets in the form of foreign securities (for the USA this index makes only 7,5%). However, growth of international activity of private financial institutes – pension funds, insurance companies, mutual funds, trusts and other – has the main line since 1980th. The globalization of world financial markets is an objective process reflecting the growing degree of world economic communications. This process assists to more effective allocation of financial resources.
Relocation of such resources nowadays is mostly directed by small and middle-sized companies worldwide that are engaged in this complex "game" with funds, financial institutes and investors in different spheres of the economical life of our planet.
Some regulation is strictly brought to such markets, but still there are a lot of aspects which give the ability to speculate, to have profits as well as losses for small participants only from the speculation process itself and nothing else. Maybe, the whole result of this can be seen only after ten or twenty years.
