anyone know how to do it? thanks

Consider a portfolio with a 65% allocation to stocks and 35% to bonds. The portfoli has a market value of $200 million. The beta of the stock position is 1.15, and the modified duration of the bond position is 6.75. The portfolio manager wishes to increase the stock allocation to 85% and reduce the bond allocation to 15% for a period of six months. In addition to altering asset allocations, the manager would also like to increase the beta on the stock position to 1.20 and increase the modified duration of the bonds to 8.25. A stock index futures contract that expires in six months is priced at $157,500 and has a beta of 0.95. A bond futures contract that expires in six months is priced at $109,000 and has an implied modified duration of 5.25. The stock futures contract has a multiplier of one. Question 3 (5 points) You observed that when a stock you held increased in value from $34 to $39 tha the calls on this stock increased in value from $2 to $4. Based on thses values, calculate the value of delta. -0.40 0.40 0.10
