The mechanism of finance in this market has large maturity periods. The insecurity and inaccurate prediction on the expected rate of returns or even possibility of losses in an investment is defined as “risk” in financial terms.


The Capital Market Theory was created upon the Markowitz Portfolio Model. Their crucial and important assumptions of the above mentioned theory are as follows;
• All investors are resourceful investors- Investors follow Markowitz idea of the efficient frontier and thus prefer to invest in ranges of and along the boundary.
• Investors borrow/lend money at risk-free rates- These risk-free rates are fixed at any point of time

This is calculated by taking a risk measure (beta) that compares the returns of the asset to the market over a period of time and to the market premium (Rm-rf).
The present risk free-rate is 5%, S&P 500 is likely to yield to 12% next year. You therefore intend to calculate the rate of return JOB will have next year. You hence substitute the beta value, 1.9 into the formula. The whole market employs a beta value of 1.0, and therefore JOBS beta of 1.9 clearly indicates that it transmits extra risk than the overall market; and hence we should expect high returns exceeding 12% of S&P 500. R = 5% + 1.9 (12% -
