Part 1:
Question 1:
The risk of the shares is detected adequately with the help of standard deviation, as it
evaluates the level of volatility, which can be detected for an investment. The standard
deviation measures the variation in the mean returns of the stock, which can help in detecting
the volatility present within the share price movement. The generate assumption for the
shares is normal distribution curve, which plots the historical data in accordance with the
returns. In addition, the use of dispersion statistics directly helps in detecting the magnitude
of risk present within a stock. The dispersion statistics allows the comparison of the standard
deviation for multiple shares, which can help invests to gauge into the current risk attributes
of the stocks1. As depicted in the case study standard deviation is a statistical tool for
calculating the most likely range of returns of a stock.
Question 2:
The use of more than one share in a portfolio will directly affect the level of risk,
which can be affected from an investment. However, the use of correlation coefficient can
help investors to assess the risk of both shares. The correlation conditions of a stock
relevantly help in detecting the level of similarity between the returns of a stock. The
detection allows the investor to determine the level of risk that the portfolio holds with the
combination of two stocks. the formula for the standards deviation is depicted in the below
figure, which indicates that without the calculation of correlation the actual risk attributes of
the stock is not detected. The case study also indicates the significance of added risk, which
