First we will specify Investment as “ committedness of money or capital to buy fiscal instruments or other assets in order to derive profitable returns in signifier of involvement, income, or grasp of the value of the instrument ” ( Investment, 2010 ) and Risk “ is an unsure result or opportunity of an inauspicious result. ” ( Risk, 2010 )
In any investing there is bound to be categorised hazards viz. Standalone hazard and Portfolio hazard.

Harmonizing to an online station by phillykelloggguy ( 2008 ) the standalone hazard measures the undiversified hazard of an single plus. An investor has the option to put in a individual plus which will be explained subsequently with an illustration.
But on the other manus, there are portfolios, which is a group of single assets organizing a individual investing for an investor.
This portfolio is exposed to what is known as portfolio hazard, this hazard is farther broken down into other hazards and harmonizing to Scott Besley, E F. Brigham ( 2008 ) those hazards are diversifiable hazard ( company-specific, unsystematic ) and non-diversifiable ( Market Risk, systematic ) .
An investor who merely acquires a individual plus as an investing, that plus is known as standalone plus. This plus will be exposed to what is known as Standalone hazards. An illustration will be purchasing stocks deserving RM 100.000,00 in Oil industry merely. The likely goon of your hard currency flow worsening or losing the stocks is high due to standalone hazards.
But harmonizing to ( Brigham and Daves 2007 ) the hazard of a individual plus ‘s hard currency flow can be considered on a standalone footing, If this investing hard currency flow is combined with other assets hard currency flows so its hazard is reduced through variegation with the overall purpose of bettering the investing expected return while cut downing hazard.
If the same investor above had known about variegation, he could hold invested the RM 100.000,00 as follows, 20 % bargain stocks in a motor industry, 20 % in belongings, 20 % in security bonds, 20 % bargain stock in telecommunication industry and 20 % bargain stock in oil industry. In the scenario above the investor has acquired more than one plus and one time all assets hard currency flows have been combined the investor has created a portfolio of assets, which is maximizing returns for a given degree of hazard.
Other writers Stephen Kealhofer, Jeffrey R. Bohn ( 2001 ) province that “ Measuring the variegation of a portfolio means stipulating the scope and likeliness of possible losingss associated with the portfolio. All else equal, a well-diversified portfolio is one that has a little likeliness of bring forthing big losingss. ”
This portfolio is exposed to portfolio hazard or market hazards. These hazards are impossible to extinguish and the investor is compensated for excluding this hazards.
There are discoverers who are known as hazard averters, they tend to hold portfolios that have low-risk with guaranteed certain returns. But it is safe to state that the higher return you desire the greater the hazard you must digest. So if an investor with low-risk portfolio wants to derive a higher return on an investing, the investor has to remix the assets in the low-risk portfolio. Let us utilize the illustration of the investor above who invested RM 100.000,00 in purchasing stocks in 5 different industries. If this investor wants a low-risk portfolio so 20 % – 40 % of the portfolio will be invested in stocks and the staying per centum will be invested in fixed involvement investings ( authorities and corporate bonds ) [ figure 1 ] .
But on the other manus if the investor wants high return which will automatically include high hazard, so 80 % of portfolio will be invested in stocks and the staying per centum in hard currency or fixed involvements investings [ figure1 ] . The investor has leverage a low hazard portfolio for higher returns.
[ Figure 1 ] Investor Risk Profile, ( Outlook Financial Solutions 2006 )
Harmonizing to ( Awerbuch, Bazilian et Al. 2008 ) “ investors have learned that an efficient portfolio takes no unneeded hazard to its expected return. In short, these investors define efficient portfolios that maximize the expected return for any given degree of hazard, while minimising hazard for every degree of expected return. ”
Investors today tend to utilize modern portfolio theory ( MPT ) which entails that a portfolio should include some security assets. Wikipedia ( 2010 ) gives the undermentioned illustration of MPT, when monetary values in the stock market autumn, monetary values in the bond market frequently addition, and frailty versa. A aggregation of both this types of assets can therefore hold lower overall hazard in a portfolio than either separately.
Some investor usage borrowed money to buy a security in a low-risk portfolio, if the security bought with borrowed money returns a loss, so the investor will be dependable to pay back that loss incurred to the borrower, but if the security consequences in a addition, so the investor has made a net income without utilizing his initial capital.
For any investor to gain high return from a low-risk portfolio, combinations of low hazard assets and high hazard assets have to be combined in the portfolio. Some investors like belongings assets
Figure 2 shows the types of assets in relation to the returns and hazards. It shows that belongingss returns are high but the hazard besides increases. It besides shows which assets to get to convey down a comparatively high hazard portfolio to a low hazard portfolio.

Equilibrium is defined as “ A province of remainder or balance due to the equal action of opposing forces.
( Wikipedia, 2010 )
Looking at Table 1 provided,
EXPECTED RETURN ON SECURITY
BETA OF SECURITY
Market return 15 % Risk free rate 8 %
For a security to be in an equilibrium state of affairs the expected ROR is equal to the needed ROR and it may fall on the Security Market Line ( SML ) which is the province of remainder mentioned in the definition. Harmonizing to Investopedia ( 2010 ) when the securities are plotted on the graph, the securities that are above the SML are said to be undervalued and those securities that are below the SML are said to be overvalued. Although in my instance I think it should be the other manner around, overvalued stocks should be above the SML and undervalued below the SML.
To find all this theory mentioned above, we will be plotting a Security Market Line ( SML ) .
Wikipedia ( 2010 ) defines SML as “ a graphical representation of the Capital plus pricing theoretical account. It displays the expected rate of return of an single security as a map of systematic, non-diversifiable hazard ( its beta ) . ”
To plot the graph, Graph Setup 4.3 package will be used.
The incline of the SML will be plotted on the undermentioned points on the graph harmonizing to betas axis of 0.5, 1.0 and 2.0, but foremost we need to calc the market premium:
Market return – Risk free rate = Market hazard premium
15 % – 8 % = 7 %
Using the market premium, we will be ciphering the needed return of the betas mentioned above,
Risk free rate + Market premium ( Beta ) = required rate of return
8 % + 7 % ( 0.5 ) = 11.5
8 % + 7 % ( 1.0 ) = 15 same per centum as the Market return.
8 % + 7 % ( 2.0 ) = 22
Figure 3 ( Graph 4.3 package ) SML
Figure 3 clearly indicates the ruddy line as the SML and were the security beta = 1.0 the needed rate of return = 15 % .
To plot each security on the graph, we need to cipher the needed return of each utilizing the expression by ( Kobold 1986 ) :
Security 1 Required Rate of Return:
17.1 = 8 % + ( 15 % – 8 % ) 1.3
= 8 % + 7 % ( 1.3 )
= 8 % + 9.1 %
Required Rate Of Return
Table 2 ( Consequences after ciphering the remainder of the securities ROR )
The graph is now plotted utilizing the Table 2 needed rate of return against the beta of each security in Table 1, represented by black squares boxes in figure 4.
Figure 4 ( Graph 4.3 package ) SML
Security 1 expected return is equal to the needed rate of return 17.1 it is in an equilibrium state of affairs, plotted on SML.
Security 2 expected return is 10.9 and it ‘s less than required rate of return 13.6, it is overvalued. “ The investor would be accepting less return for the sum of hazard assumed. ” ( Investopedia, 2010 )
Security 3 expected returns 18.2 is greater than required rate of return 17.8, it is undervalued. “ The investor is accepting a greater return for the built-in hazard. ” ( Investopedia, 2010 )
Security 4 expected return equal to the needed rate of return 18.5 it is in an equilibrium state of affairs. Plotted on SML.
Security 5 expected returns 9.8 is greater than required rate of return 9.4, it is undervalued. “ The investor is accepting a greater return for the built-in hazard. ” ( Investopedia, 2010 )
As shown in figure 5, Security 2 is plotted in the shaded country. Meaning Market hazard premium is 7 % , so it is an mean security.
