Suppose you held a diversified portfolio consisting of a $7,500 investment in each of 20 different common stocks. The portfolio's beta is 1.95. Now suppose you decided to sell one of the stocks in your portfolio with a beta of 1.0 for $7,500 and use the proceeds to buy another stock with a beta of 0.80. What would your portfolio's new beta be? Do not round intermediate calculations. Round your answer to two decimal places.

You have a portfolio with a standard deviation of 23% and an expected return of 17%. You are considering adding one of the two stocks in the following table: If after adding the stock you will have 25% of your money in the new stock and 75% of your money in your existing portfolio, which one should you add?

8.2 An individual has $20,000 invested in a stock with a beta of 0.8 and another $55,000 invested in a stock with a beta of 1.8. If these are the only two investments in her portfolio, what is her portfolio's beta? Do not round intermediate calculations. Round your answer to two decimal places.

You have a portfolio with a beta of 1.59. What will be the new portfolio beta if you keep 86 percent of your money in the old portfolio and 14 percent in a stock with a beta of 0.58? (Round your answer to 2 decimal places.) New portfolio beta: ___.__%

Ranking investments by expected returns What makes for a good investment? Use the approximate yield formula or a financial calculator to rank the following investments according to their expected returns. Round the answers to two decimal places. Do not round intermediate calculations.   Buy a stock for $45 a share, hold it for 3 years, then sell it for $75 a share (the stock pays annual dividends of $3 a share). % Buy a security for $25, hold it for 2 years, then sell it for $60 (current income on this security is zero). Do not round intermediate calculations. % Buy a 1-year, 12 percent note for $950 (assume that the note has a $1,000 par value and that it will be held to maturity). Do not round intermediate calculations. %

You own a portfolio that has $2,045 invested in Stock A and $4,096 invested in Stock B. If the expected returns on these stocks are 14 percent and 8 percent, respectively, what is the expected return (in percent) on the portfolio? Answer to two decimals.

You own a portfolio equally invested in a risk-free asset and two stocks. One of the stocks has a beta of 1.27 and the total portfolio is equally as risky as the market. What must the beta be for the other stock in your portfolio? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Beta

Suppose you hold a diversified portfolio consisting of a $7,500 investment in each of 20 different common stocks. The portfolio beta is equal to 1.12. Now, suppose you have decide to sell one of the stocks in your portfolio with a beta equal to 1.0 for 7,500 and to use these proceeds to buy another stocks for your portfolio. Assume the new stocks beta to 1.75. Calculate your portfolios new beta.

Your portfolio is comprised of 30 percent of Stock X, 20 percent of Stock Y, and 50 percent of Stock Z. Stock X has a beta of 1.05, Stock Y has a beta of 0.80, and Stock Z has a beta of 1.43. What is the beta of your portfolio? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
