1. Suppose that you can trade a riskless asset that yields 5% and two risky assets A and B. The expected return of asset A is 8% and that of asset B is 11%, while the standard deviation of asset A is 14% and that of asset B is 23%. The covariance between assets A and B is ?? 0:0322. Solution . rA,B= CovAR(A,B) / [(? A)(? B)] = -0. 0322 / (14%)(23%) rA,B = -1 But when rA,B = -1, (? p)^2 = [wA(? A) – wB(? B)]^2, ? p = wA(? A) – wB(? B) Is there is no risk fo the portafolio, then ? p = 0 So this means that: 0 = 14%(wA) – 23%(1 – wA), solve this for wA, wA = 0. 6216 wB = 1 – wA, wB = 0. 3784 E(Rp) = 0.

6216(8%) + 0. 3784(11%) = 9. 1352% Suppose that each one of the securities has a value of $100, Cash Flow Today Cash Flow 1 year from today Buy 0. 6216 units of A -$62. 16 $62. 16(1. 08) = +$67. 13 Buy 0. 3784 units of B -$37. 84 $37. 84(1. 11) = +$42. 00 Short 1 unit of risk-free +$100 -$100(1. 05) = -$105 Net Cash Flow 0 +$4. 13 What today will be $4. 13/(1. 05) = $3. 93 2. You are the risk manager in a major investment bank. The bank’s current portfolio consists of U. S. stocks (50%), bonds (20%), and derivatives (30%).

### The expected returns and standard deviations of these investments are

### The Essay on Intangible Asset Ias Accounting Standards

IASB WEBSITE ACCESSED ON 24/10/2003 12 PM S 38: Intangible Assets IAS 38, Intangible Assets, was approved by the IASC Board in July 1998 and became operative for annual financial statements covering periods beginning on or after 1 July 1999. IAS 38 supersedes: . IAS 4, Depreciation Accounting, with respect to the amortisation (depreciation) of intangible assets; and. IAS 9, Research and ...

Based on risk considerations alone, which of the three emerging markets is the best investment? Assume that the investment in the new market is based by borrowing on the riskless asset, and that it is a very small part of the bank’s overall investment. The market with the smallest risk contribution can be figured by determining the CovAR of each market to the portfolio. CovAR(RA, RM) = (? A)var(RM) Thus, it eliminates the need to determine Var(RM).

If the CovAR of Polynesia to the bank’s portfolio can be measured by first determining the covariance between stocks, bonds, and derivatives.

Then, these values can be summed to compute the CovAR of Polynesia to the bank’s portfolio. CovAR(Polynesia, Stocks) = xstocks(? Polynesia)(? stocks)(weight of stocks) = 0. 4 * 0. 3 * 0. 25 * 0. 5 = 0. 015 With similar calculations, CovAR(Polynesia, Bonds) = 0. 00162 and CovAR(Polynesia, Derivatives) = 0. 009 CovAR(Polynesia, portfolio) can be computed by summing CovAR(Polynesia, Stocks), CovAR(Polynesia, Bonds), and CovAR(Polynesia, Derivatives) CovAR(Polynesia, portfolio) = 0. 015 + 0. 00162 + 0. 009 = 0. 2562 With similar calculations, CovAR(Micronesia, portfolio) = 0.

02513, CovAR(NewCaledonia, portfolio) = 0. 038808 The best option of investment is the bank is Micronesia. 3. Stocks X, Y, and Z have the same expected return 8% and the same standard deviation 19% (a)Compute the standard deviation of the equally weighted portfolio if the correlation between all pairs of stocks is 1:0. Explain the intuition behind this result. r = 1, ? p = 19% With a perfect positive correlation, there is no idiosyncratic risk, thus there are no benefits of diversification. (b) Compute the standard deviation of the equally weighted portfolio if the correlation between all pairs of stocks is 0:5.

Using excel, when r = 0. 5, ? p = 15. 51% (c) Compute the standard deviation of the equally weighted portfolio if the correlation between all pairs of stocks is 0:0. Using excel, when r = 0, ? p = 10. 97% (d) Compute the standard deviation of the equally weighted portfolio if the correlation between all pairs of stocks is 0:5. Using excel, when r = -0. 5, ? p = 0% (e) Explain intuitively in which case above (a) to (d) (if any) is the equally weighted portfolio the minimum variance portfolio? (No computation is needed. ) The minimum variance portfolio is seen when r = -0. 5.

The purpose of this article is to illustrate how using statistical data, such as standard deviation, can help a cattleman choose the best lot of calf’s at auction. The statistical data used in these decision making processes can also help the cattleman with future analysis of the lots purchased and existing stock. Research Question: How can understanding the standard deviation of weights in a lot ...

Here, ? p = 0% (f) How does your answer to part (e) change if stocks X, Y, and Z have the same expected return 11% instead of 8% and nothing else is changed? No change (g) How does your answer to part (e) change if stocks X, Y, and Z have the same standard deviation 15% instead of 19% and nothing else is changed? No change 4. Your rich uncle asks you financial advice. He is currently holding a portfolio of 30% T-bills and 70% Microsoft stock. The beta of Microsoft is 1. 2 and the standard deviation is 37. 95%. You decide to base your advice on the CAPM. The T-bill rate is 5%.

The market portfolio has expected return 15% and standard deviation 20%. (a)What is the expected return of your uncle’s portfolio? E(RM) = 5% + 1. 2(15% – 5%) = 17% E(Rp) = (3/10)5% + (7/10)17% = 13. 4% (b) What is the standard deviation of your uncle’s portfolio? (? p)^2 = (7/10)^2(0. 3795)^2 + (3/10)^2(0)^2 + 0 = 0. 0705699 ? p = 0. 0705699^0. 5 = 0. 26565 = 26. 565% (c) You decide to recommend to your uncle a portfolio that has the same expected return as his portfolio but the lowest possible standard deviation. Which is this portfolio, and what is its standard deviation?

13. 4% = wTP(15%) + (1 – wTP)(5%) solving for wTP, wTP = 0. 84 wT = 1 – wTP, wT = 0. 16 (? p)^2 = 0. 84^2(0. 2)^2 = 0. 028224 ?p = 0. 168 = 16. 8% 5. Consider market portfolio and three risky assets: A, B, and C. Over the next year, only three scenarios of how the economy will develop can happen with equal probability. The table below describes, in each scenario, returns predicted by analysts for the market portfolio and for the three risky assets. Economy Market A B C Boom 17% 11% 3% 2% Mediocre 6% 11% 3% 2% Recession -2% 2% 7% 4%

(a) What are the expected returns and the standard deviations of returns from in- vesting into the market portfolio and into each of the three risky assets? E(RM) = (1/3)17% + (1/3)6% + (1/3)-2% = 7%E(RM) = 7% With similar calculations, E(RA) = 8%, E(RB) = 4. 33%, E(RC) =2. 67% (? M)^2 = (1/3)(17% – 7%)^2 + (1/3)(6% – 7%)^2 + (1/3)(-2% – 7%)^2 = 0. 0061 ? M = 0. 0061^0. 5 = 0. 0779 = 7. 79% With similar calculations, ? A = 4. 24%, ? B = 1. 89%, ? C = 0. 94% (b) Covariance of returns of the market portfolio with asset A is where pBoom, pMediocre, and pRecession are the probabilities of the three scenarios to occur.

What Is Statistics? American Heritage Dictionary (R) defines statistics as: "The mathematics of the collection, organization, and interpretation of numerical data, especially the analysis of population characteristics by inference from sampling." The Merriam-Webster's Collegiate Dictionary (R) definition is: "A branch of mathematics dealing with the collection, analysis, interpretation, and ...

The correlation of returns of the market portfolio with the returns of asset A is _(RM;RA) = Cov(RM;RA) _ (RM) _ (RA) Use the formulas above tend the covariance’s and correlations of returns of assets A, B, and C with the returns of the market portfolio. Using formula, Cov(RM,RA) = 0. 0027, Cov(RM,RB) = -0. 0012, Cov(RM,RC) = -0. 0006 Using formula, ? (RM,RA) = 0. 8171, ? (RM,RB) = -0. 8171, ? (RM,RC) = -0. 8171 (c)What are the betas of assets A, B, and C? ?A = CovAR(RM,RA) / Var(RM) = 0. 0027 / 0. 0061 = 0. 4451? A = 0. 4451 With similar calculations, ? B = -0. 1978, ? C = -0. 0989

(d)If the riskless rate is 3. 5%, what are the expected returns of A, B, and C as predicted by the CAPM? CAPM, E(Ri) = rf + ? i [ E(RM) – rf ] E(RA) = 3. 5% + 0. 4451( 7% – 3. 5% ) = 5. 06%E(RA) = 5. 06% With similar calculations, E(RB) = 2. 81%, E(RC) = 3. 15% (e) Draw a graph that contains the riskless asset, the market portfolio, and the three risky assets A, B, and C. Draw the SML in this graph. (f) Find alphas of risky assets A, B, and C. Indicate alphas of each risky asset in the alpha(A) = 8% – 5. 06% = 2. 94%, alpha(B) = 4. 33% – 2. 81% = 1. 52%, alpha(C) = 2. 67% – 3. 15% = -0. 48%
