Investment Houses

The primary players are the small group of large investment houses which are huge financial corporations.  Some of them were founded more than a hundred years ago and originally functioned as investment banks that helped to issue stocks and bonds.  Over there years, their activities broadened and today they are active in a wide variety of fields.


A typical investment house includes the following departments:

  • Investment Banking.
