I want solution of Q)2

1) Suppose that an investor considers investing his/her money in two stocks A and B and also in a riskless T-Bill. The expected return of Ais 25% and expected variance of A is 9%. The expected return of Bis 18% and expected variance of B is 4%. The riskless return of the T-Bill is 10%. The correlation coefficient between A and B is 0.5. The correlation coefficient between the stock A and T-Bil is 0.2 and the correlation coefficient between stock B and the T-Bilis -0.3. Given this a) Assume that this investor invests 40% of his/her money in stock A, invests 40% of his/her money in stock B and invests the rest of money in T-Bills. What will then be the expected return and the expected variance of that portfolio? b) We then tell the investor it is possible to minimize the risk of a portfolio by choosing optimal weights. Then the investor asks us what may be the optimal weights that will minimize the risk if he/she chooses an expected portfolio return of 20%.? Set the Lagrangian to find the optimal weights of that portfolio using the numerical values given above and also set the equations that will lead to minimum risk portfolio. (Solution of these equations are not required) 2) a) We are provided with the following information. We expect that the return of the market portfolio (index) will be 20% in the coming year. The current riskless T-Bil rate is 12%. We also expect that the variance of the market portfolio (index) will be 8% in the coming year. We want to find the expected return of a stock A in the coming year. We know that the covariance between this stock A and the market (index) is 0.14. a) Given this; what may be the expected return of stock A? b) What may be the systematic risk of stock A? b) Suppose that the investor adds a second stock B to his/her portfolio (in addition to A) whose expected return is 16% and invests equal shares in stock A and stock 212 B. How much this investor may gain from his/her portfolio if the market (index) goes up by 35%? 3) The stock of Zircon corp.is expected to distribute a dividend of $5 per year next year. We expect a market (index) return of 24% and the beta of Zircon corp.is 0.8. The riskless rate of return is 4%. Analysts expect a 5% growth rate in dividends of that stock in the coming 2 years and then they expect that the dividend growth rate will accelarate to 12% starting in year 3. Given this; find the fundamental price of Zircon stock. 4) Give clear and brief definitions of the following a) Quick Ratio b) ROE C) Underwriter in a stock market d) P/E Ratio
