Q 1. You are given the following data on three securities, A, B, and the market, M:
a. Compute the correlation between A and the market, and B and the market.
b. Based on your answer to part (a), which of the two securities, A or B, is better to be combined into a portfolio with M? Explain briefly.
c. Compute the expected return and standard deviation for a portfolio formed between M and your choice in part (b). Then compute the weighted-average standard deviation of this portfolio and explain why the portfolio’s actual standard deviation is less than just holding any of the three securities, all of which have a standard deviation of 15% and an expected return of 10%.
d. Compute the systematic risk (ß) CAPM expected return for your choice in part (b). Why is it less than 10%? Explain in the context of systematic and total risk.
Q 2. You are given the following data for options on a common stock;
S=$102 X=$75 r=2.5% T=3 month δ=.2
a. Use the Black-Scholes Option Pricing Model to find the price of the options
i) Find 
and d2=d1-δ√T
ii) Use your answers from a(i) to find N(d1) and N(d2) . Note: Round your answers to 2 decimal places before looking the values up in the tables.
(iii) Use the Black-Scholes OPM to find C
(iv) Use the put-call parity relationship to find the value of P.
b) State the intrinsic value and the speculative premium for the call and put options. Why is the speculative premium so small for each option?
3) A call option has a value of C=$5 and a put has a value of P=$3. Both options have an exercise price of X=$20. The options are to expire today.
a) Compute the payoff schedule for the call option using the following stock prices,S, and draw a graph of the payoff schedule.
