Question 7
Use this table for the next 5 questions:

Bacon and Associates, a famous Northwest think tank, has provided probability estimates for the four potential economic states for the coming year. The probability of a boom economy is 20%, the probability of a stable growth economy is 45%, the probability of a stagnant economy is 20%, and the probability of a recession is 15%.

INVESTMENT Forecasted Returns for Each Economy

    Boom    Stable Growth   Stagnant    Recession

Stock 25% 12% 4% 12%
Corporate Bond 9% 7% 5% 3%
Government Bond 8% 6% 4% 2%

Estimate the expected return on the stock.

Normal 0.50 0.060 0.180 0.120
Recession 0.15 0.060 0.210 0.060
What is the expected return for Asset E?

  Financial Mathematics Problem Set Question 1: Profit on Investments 1. Investment 1: - Original Cost: $34.00 - Selling Price: $26.00 - Distributions Received: $2.00 - Profit = (Selling Price + Distributions) - Original Cost - Profit = ($26.00 + $2.00) - $34.00 = $-6.00 2. Investment 2: - Original Cost: $955.00 - Selling Price: $1000.00 - Distributions Received: $240.00 - Profit = (Selling Price + Distributions) - Original Cost - Profit = ($1000.00 + $240.00) - $955.00 = $285.00 Question 2 & 3: Return on Investments 3. Investment 1: - Percent Return = ((Selling Price + Distributions) - Original Cost) / Original Cost * 100% - Percent Return = (($26.00 + $2.00) - $34.00) / $34.00 * 100% = -17.65% 4. Investment 2: - Percent Return = (($1000.00 + $240.00) - $955.00) / $955.00 * 100% - Percent Return = $285.00 / $955.00 * 100% = 29.84% Question 4: Holding Period Return 5. Holding Period Return = ((Selling Price - Purchase Price) + Distributions) / Purchase Price- HPR = (($50,000 - $8,500) / $8,500) * 100% = 488.24% Question 5: Annual Compounded Return 6. Annual Compounded Return formula is required to calculate this. Question 6: Highest Annual Compounded Return 7. Calculate the annual compounded return for each investment and compare to find the highest. Question 7-9: Expected Returns 8. Expected Return = Sum(Probability * Return for each state)- Stock: (0.20 * 25%) + (0.45 * 12%) + (0.20 * 4%) + (0.15 * 12%) = 12.05% - Corporate Bond: (0.20 * 9%) + (0.45 * 7%) + (0.20 * 5%) + (0.15 * 3%) = 6.60% - Government Bond: (0.20 * 8%) + (0.45 * 6%) + (0.20 * 4%) + (0.15 * 2%) = 5.30% Question 10: Variance of Stock 9. Variance of Stock = Sum(Probability * (Return for each state - Expected Return)^2) Question 11: Standard Deviation of Corporate Bond 10. Standard Deviation of Corporate Bond = Square Root of Variance Question 12: Expected Return for Asset E 11. Expected Return for Asset E = Sum(Probability * Return for Asset E in each state) I can provide detailed calculations for each question if needed or additional assistance on any specific problem in this set!
