(a) Stock A has less systematic risk than stock B, so stock A's return should be less than stock B's.

(b) Stock B has the same systematic risk as the market, so its return should be the same as the market's.

(c) Stock B has the same beta as the market, so it also has the same total risk as the market.

(d) If stock A and B were combined in a portfolio with weights of 50% each, the beta of the portfolio would be 0.75.

(e) Stocks A and B have more systematic risk than the risk free security (government bonds) so their return should be greater than the risk free rate.

(a) 11.75%

(b) 11.82%

(c) 13.54%

(d) 13.78%

(e) 20.84%

(a) A positive NPV and should be accepted.

(b) A zero NPV.

(c) A negative NPV and should be rejected.

(d) A large amount of diversifiable risk.

(e) Zero diversifiable risk.

(a) 27 months (t=27 months).

(b) 38 months (t=38 months).

(c) 40 months (t=40 months).

(d) 43 months (t=43 months).

(e) 79 months (t=79 months).

(a) 1.180572 AUD per USD

(b) 0.848966 AUD per USD

(c) 0.847047 AUD per USD

(d) 0.755566 AUD per USD

(e) 0.752954 AUD per USD

(a) 2.7% pa.

(b) 3.0% pa.

(c) 3.5% pa.

(d) 3.3% pa.

(e) 3.8% pa.

(a) Alice has $6,000 cash, owes $10,000 credit card debt due immediately and 100% owns a sole tradership business with assets worth $10,000 and liabilities of $3,000.

(b) Billy has $10,000 cash, owes $6,000 credit card debt due immediately and 100% owns a corporate business with assets worth $3,000 and liabilities of $10,000.

(c) Carla has $6,000 cash, owes $10,000 credit card debt due immediately and 100% owns a corporate business with assets worth $10,000 and liabilities of $3,000.

(d) Darren has $10,000 cash, owes $6,000 credit card debt due immediately and 100% owns a sole tradership business with assets worth $3,000 and liabilities of $10,000.

(e) Ernie has $1,000 cash, lent $3,000 to his friend, and doesn't have any personal debt or own any businesses.

(a) Mr Blue's expected utility of wealth from gambling is 7.5 while refusing is 6.25. So the gamble makes him more happy.

(b) Miss Red's expected utility of wealth from gambling is 7.5 and refusing is also 7.5. This is why she is indifferent.

(c) Mr Blue's certainty equivalent of the risky gamble is $70.71. So he would pay to take part in the gamble.

(d) Miss Red's certainty equivalent of the risky gamble is $50.

(e) Mrs Green's certainty equivalent of the risky gamble is $70.71. She would enjoy taking part in the gamble.

(a) The geometric average of the gross discrete returns (GAGDR) equals 1.04075 which is 104.075%.

(b) ##\exp \left( \text{GAGDR} \right) = \text{AALGDR}##. The natural exponent of the GAGDR equals the arithmetic average of the logarithms of the gross discrete returns (AALGDR).

(c) ##\text{GAGDR}^T = \left( P_T/P_0 \right)##. The GAGDR raised to the power of the number of time period that it's measured over equals the ratio of the first and last prices.

(d) ##\text{GAGDR} = \exp \left( \text{AALGDR} \right)##. This is always true, regardless of the distribution of the prices or returns. The logarithm of the geometric average of the gross discrete returns (LGAGDR) is always equal to the arithmetic average of the logarithm of the gross discrete returns (AALGDR).

(e) ##\text{AAGDR} \approx \exp \left( \text{AALGDR} + \text{SDLGDR}^2/2 \right)##. This is only approximately true and depends on the distribution of the prices and returns. It's asymptotically true as the time period that the returns are measured over reaches infinity.

(a) Alice has a net long position of 2 contracts.

(b) Bob has a net short position of 7 contracts.

(c) Chris has a net long position of 14 contracts.

(d) Delta has a net short position of 5 contracts

(e) Trading volume is 16 contracts and open interest is 16 contracts.
