Risk is usually measured by the use of beta. Beta is apply as an indicator of how sensitive a stock is, towards market forces. A security that has a bet greater than 1 is said to be savage while a security that has a beta less than one is less risky. Risky securities are often associated with high dispels. In the choice of the securities, the companies should not be correlated. That will ensure that the risk involved in the portfolio is minimal.Our group has considered six companies.

A good portfolio should have securities that are not correlated (Levinson, 2006, 155). That will help in ensuring that a failure in one sedulousness will not lead to a failure in the other. The first step in the evaluation in considering the securities is finding the second- station rate of return. The average rate of return can be calculated by using the geometric or arithmetic mean. The rate of return was as follows,From the analytic thinking of the rate of return, Google has the best rate of return while Wal-Mart is associated with the lowest rate of return. That means that if two investors invest the same amount of money in the two different companies, the investor at Google will earn more in terms of return.
