Using Excel‚ produce a chart showing alternative risk-return combinations in terms of 5% (e.g. 0% in WBK and 100% in WES‚ 5% in WBK and 95% in WES‚ 10% in WBK and 90% in WES‚ etc.) from the two investments. Interpret your results‚ also in comparison to investing in either of the individual stocks. Meanwhile please also calculate the minimum standard deviation of the portfolio contains these

Security B has an expected return of 11% a standard deviation of returns of 10%‚ a correlation with the market of .75 and a beta coefficient 0.5. Which security is more risky? Why? From the problem‚ the standard deviation of Security A is 30% and the standard deviation of Security B is 10%. Now let’s look at the CV of each

Standard market risk factors are stock prices‚ interest rates‚ foreign exchange rates‚ and commodity prices. 2.2 Definition of Standard Deviation In statistics and probability theory‚ standard deviation shows how much variation or "dispersion" exists from the average (mean‚ or expected value). A low standard deviation indicates that the data points tend to be very close to the mean‚ whereas high standard deviation indicates that the data points are spread

EXECUTIVE SUMMARY It is difficult for business leaders to open a newspaper or read a journal without seeing the warning that their only competitive advantage in the world economy is the knowledge embodied in the people they employ. Invest in your people‚ the gurus say‚ and your business will survive and profit. Yet when these leaders ask their Human Resource (HR) specialists to present them with proposals to increase the firm’s human capital wealth‚ these proposals are generally filled with vague

in this experiment. When trialing the octagon parachute‚ the results show very accurate data. It shows that it is the slowest speed‚ and experiences the most air resistance. The square parachute has the second most accurate data‚ based on the standard deviation from the mean. The speed of the square is the second slowest‚ and experiences great air resistance. The circle experiences fast rates placing it in third. The data is not as precise as the square and octagon. The rectangle experiences very fast

Planning Introduction Stomata are pores on the bottom of leaves of vascular plants. The function of stomata is to allow gaseous exchange (transpiration) between the plant and the external environment (see diagrams below). This process is carried out by the plant‚ which controls the opening and closing of stomata via the guard cells. The more stomata a leaf contains the greater the rate of gas exchange and the less water it will be able to accumulate. Stomatal pores are formed between
