When we look from an investor viewpoint, he/she may not be willing to invest in individual assets. This may be due to the fact that the investor is unaware of the expected degree of return and risk borne by individual assets. Hence, the investor chooses to make investments in a portfolio. A portfolio can take any kind of the following combinations—only equities, only bonds, only forex, only commodities, equities and bonds, equities, bonds and forex, equities, bonds, forex and commodities, etc. A portfolio can also be of only domestic investments, only international investments or a combination of domestic and international investments. As the present study focuses only on financial markets, commodity market investment as a part of portfolio is not accounted for. The choice of any of the above portfolio is also based on the degree of risk a rational investor is ready to bear.
