b. Now calculate the returns in each month of a portfolio that invests an equal amount each month in the two stocks.

c. Is the variance more or less than halfway between the variance of the two individual stocks?

Answers

Answer 1

Based on the returns on Digital Cheese and Executive Fruit, the variance and standard deviation of each stock is:

Variance:

Digital cheese = 56.8 Executive fruit = 34.8

Standard deviation:

Digital cheese = 7.5Executive fruit = 5.9

This means that Digital Cheese is riskier if held alone.

What are the variances and standard deviations of the stock?

Using a spreadsheet, one can order the given returns and then find the variance using mathematical functions.

When this is done, the variances on Digital cheese and Executive fruit would be 56.8 and 34.8 respectively.

You can then take the square roots of these variances to find the standard deviations as 7.5 and 5.9 respectively.

Because Digital Fruit has a higher standard deviation, it is considered to be riskier in terms of returns.

multiple choice
No
Yes


b. Calculate the expected rate of return and standard deviation for each investment. (Do not round intermediate calculations. Enter your answers as a percent rounded to 1 decimal place.)







c. Which investment would you prefer?

Answers

Based on the scenario analysis on stocks and bonds, we know the following:

Treasury bonds will provide a higher return in a recession than in a boom. The expected return of Bonds is 9.8% and that of stocks is 11.6%. The standard deviation of Bonds is 9.24% and that of stock is 11.76%.

What does the scenario analysis on Bonds and Stocks show?

In a recession, Bond returns will be 15%. This is much higher than Bond returns in a boom of only 5%.

The expected return on bonds will be:

= ∑(Probability of Scenario x Returns in scenario)

= (0.30 x 15%) + (0.60 x 8%) + (0.10 x 5%)

= 9.8%

The expected return on stocks will be:

= (0.30 x -6%) + (0.60 x 18%) + (0.10 x 26%)

= 11.6%

Using a spreadsheet, you can input the expected returns of the stocks and the bonds to find the standard deviation to be 9.24% and 11.76%, respectively.

Self-interest and competition, in accordance with Adam Smith, function as invisible hands that direct businesses in a market-based economy.

What is self-interest?

Self-interest is commonly defined as a focus on one's own needs or interests. Self-interested behaviors are typically carried out unknowingly most of the time. Numerous philosophical, psychological, and economic theories look at how self-interest influences how people behave.

Adam Smith authored one of the most well-known works on economics, which is still used today to explain how the American economy is structured. Smith writes in Wealth of Nations about the need for essentially zero government involvement in the economy. Instead, the best outcome for customers will come through business rivalry. Smith bases his assertion that businesses will act in their own best interests on this theory.

Since the business owner depends on customers to succeed, acting in their best interest will inevitably lead to the best deals for the consumer.
