(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) Cost of debt (##r_\text{D}##).

(b) Unlevered cost of equity (##r_\text{E, U}##).

(c) Levered cost of equity (##r_\text{E, L}##).

(d) Levered before-tax WACC (##r_\text{V, LxITS}##).

(a) Asset A has a Jensen's alpha of 4.5% pa.

(b) Asset A is under-priced.

(c) The NPV of buying asset A is zero.

(d) Asset B has a Jensen's alpha of zero.

(e) Asset B is fairly priced.

(a) Asset A has the same systematic risk as asset B.

(b) Asset A has more total variance than asset B.

(c) Asset B has zero idiosyncratic risk. Asset B must be a portfolio of half the market portfolio and half government bonds.

(d) If risk-averse investors were forced to invest all of their wealth in a single risky asset, so they could not diversify, every investor would logically choose asset A over the other three assets.

(e) Assets M and B have the highest Sharpe ratios, which is defined as the gradient of the capital allocation line (CAL) from the government bonds through the asset on the graph of expected return versus total standard deviation.

(a) Green is a stock's continuously compounded rate of return, also called the log gross discrete return. ##r_\text{cc} = \ln(P_1/P_0)##

(b) Blue is a stock's future price, ##P_1##

(c) Blue is a stock's gross discrete return. ##\text{GDR} = P_1/P_0##

(d) Blue is a stock's effective rate of return. ##r_\text{eff} = (P_1-P_0)/P_0##

(e) Red is a stock's net discrete return. ##\text{NDR} = \text{GDR}-1##

(a) $95.345378

(b) $95.819741

(d) $96.296464

(e) $96.775559

(a) Buffett is clever and by reading the news and financial reports he is able to buy under-priced stocks and sell over-priced stocks. This provides evidence for rejecting the semi-strong and strong form EMH.

(b) Buffett was lucky, his strategy happened to be the right one, not due to its merits, just by chance. This provides no evidence for or against the weak, semi-strong or strong form EMH.

(c) Buffett’s investment strategy exposes investors to higher undiversifiable risk than the market and therefore deserves a higher return. This provides no evidence for or against the weak, semi-strong or strong form EMH.

(d) Buffett is an insider trader and is able to make money from his private information. This provides evidence for rejecting the semi-strong and strong form EMH. (Note: Warren Buffett is not an insider trader, he is an honest philanthropist, but assume the contrary in this answer option).

(e) Buffett may not have beaten the market because the graphs ignore dividends - the S&P500 is the price index rather than the accumulation index and BRK pays no dividends, so even though BRK has a higher capital return than the S&P500, the total returns could be equal. This provides no evidence for or against the weak, semi-strong or strong form EMH.

(a) You have the right to buy the underlying stock in 3 months’ time for a price of $50 if you want.

(b) If the dividend in 4 months were unexpectedly cancelled because the firm decided to re-invest its cash rather than pay it out then the 3 month call option price would be unaffected.

(c) If the stock price is $49 in 3 months then you wouldn’t exercise the ‘out of the money’ option.

(d) If the stock price is $51 in 3 months then you wouldn’t exercise or else you’ll incur a loss of $3.

(e) If the stock price is $57 in 3 months then you would exercise. Your profit would be $3 and payoff at maturity $7.

(a) Low unemployment rates.

(b) Low inflation rates.

(c) Low GDP growth rates.

(d) Low wage growth rates.

(e) Low labour force participation rates.

(a) Adam’s opportunity cost of picking one date per hour is 7/6 coconuts, so he picks around 1.1667 coconuts per one date per one hour.

(b) Bella’s opportunity cost of picking one date per hour is 3/5 coconuts, so she picks around 0.6 coconuts per one date per one hour.

(c) Adam’s opportunity cost of picking one coconut per hour is 6/7 dates, so he picks around 0.8571 dates per one coconut per one hour.

(d) Bella’s opportunity cost of picking one coconut per hour is 5/3 dates, so she picks around 1.6667 dates per one coconut per one hour.

(e) The gradients (rise over run) of the lines in the graph are measured in dates per one coconut per hour.
