Question 1 10 pts Consider that on January 2, 2014 (Wednesday) you decide to invest in a portfolio consisting of these 10 stocks. You want to find the optimal portfolio to invest in, so you analyze the performance of these 10 stocks over time (using past historical data from January 3, 2011 to December 31, 2013). Please construct the optimal portfolio if short selling is allowed. Use the 3-month T-bill rate as a proxy for the risk-free rate. Assume that riskless borrowing/lending is possible (Hint: Use the borrowing/lending rate on January 2, 2014 - use the specific value provided in the Excel file for this assignment). Please solve this part using Excel Solver (GRG Nonlinear Method). What is the proportion of your funds invested in Tesla? Please report the full number (not the %), rounded to three decimals. Question 2 10 pts Please construct the optimal portfolio if short selling is not allowed. Solve this part using Excel Solver (GRG Nonlinear Method). What is the proportion of your funds invested in Accenture PLC Ireland? Please report the full number (not the %), rounded to three decimals. 0.3439 DATE Returns_IBM Returns_KR Returns_TSLA Returns DAL Returns_TRV Returns XOM Returns TM Returns ACN Returns_XRX Returns_BRK _3monthTbill 16-Feb-11 2.6979 8.275 -0.6723 0.1853 0.8678 0.7637 2.7313 2.71 -0.0235 0.12 17-Feb-11 0.5141 -0.5599 -4.5693 -1.4382 0.5382 0.227 -0.2455 1.1796 0 -0.0353 0.09 18-Feb-11 0.3653 0.0433 -1.7797 -

You want to find the optimal portfolio to invest in, so you analyze the performance of these 10 stocks over time (using past historical data from January 3, 2011 to December 31, 2013). Please construct the optimal portfolio if short selling is allowed. Use the 3-month T-bill rate as a proxy for the risk-free rate. Assume that riskless borrowing/lending is possible (Hint: Use the borrowing/lending rate on January 2, 2014 - use the specific value provided in the Excel file for this assignment). Please solve this part using Excel Solver (GRG Nonlinear Method). What is the proportion of your funds invested in Tesla? Please report the full number (not the %), rounded to three decimals. Question 2 10 pts Please construct the optimal portfolio if short selling is not allowed. Solve this part using Excel Solver (GRG Nonlinear Method). What is the proportion of your funds invested in Accenture PLC Ireland? Please report the full number (not the %), rounded to three decimals. 0.3439 DATE Returns_IBM Returns_KR Returns_TSLA Returns DAL Returns_TRV Returns XOM Returns TM Returns ACN Returns_XRX Returns_BRK _3monthTbill 16-Feb-11 2.6979 8.275 -0.6723 0.1853 0.8678 0.7637 2.7313 2.71 -0.0235 0.12 17-Feb-11 0.5141 -0.5599 -4.5693 -1.4382 0.5382 0.227 -0.2455 1.1796 0 -0.0353 0.09 18-Feb-11 0.3653 0.0433 -1.7797 -
