What is the standard deviation (not variance) of the above portfolio? Note that the stocks' covariance is given, not correlation.
Question 244 CAPM, SML, NPV, risk
Examine the following graph which shows stocks' betas ##(\beta)## and expected returns ##(\mu)##:
Assume that the CAPM holds and that future expectations of stocks' returns and betas are correctly measured. Which statement is NOT correct?
Three important classes of investable risky assets are:
- Corporate debt which has low total risk,
- Real estate which has medium total risk,
- Equity which has high total risk.
Assume that the correlation between total returns on:
- Corporate debt and real estate is 0.1,
- Corporate debt and equity is 0.1,
- Real estate and equity is 0.5.
You are considering investing all of your wealth in one or more of these asset classes. Which portfolio will give the lowest total risk? You are restricted from shorting any of these assets. Disregard returns and the risk-return trade-off, pretend that you are only concerned with minimising risk.
The following cash flows are expected:
- Constant perpetual yearly payments of $70, with the first payment in 2.5 years from now (first payment at t=2.5).
- A single payment of $600 in 3 years and 9 months (t=3.75) from now.
What is the NPV of the cash flows if the discount rate is 10% given as an effective annual rate?

The standard deviation of monthly changes in the spot price of corn is 50 cents per bushel. The standard deviation of monthly changes in the futures price of corn is 40 cents per bushel. The correlation between the spot price of corn and the futures price of corn is 0.9.
It is now March. A corn chip manufacturer is committed to buying 250,000 bushels of corn in May. The spot price of corn is 381 cents per bushel and the June futures price is 399 cents per bushel.
The corn chip manufacturer wants to use the June corn futures contracts to hedge his risk. Each futures contract is for the delivery of 5,000 bushels of corn. One bushel is about 127 metric tons.
How many corn futures should the corn chip manufacturer buy to hedge his risk? Round your answer to the nearest whole number of contracts. Remember to tail the hedge.
Question 800 leverage, portfolio return, risk, portfolio risk, capital structure, no explanation
Which of the following assets would you expect to have the highest required rate of return? All values are current market values.
On 1 February 2016 you were told that your refinery company will need to purchase oil on 1 July 2016. You were afraid of the oil price rising between now and then so you bought some August 2016 futures contracts on 1 February 2016 to hedge against changes in the oil price. On 1 February 2016 the oil price was $40 and the August 2016 futures price was $43.
It's now 1 July 2016 and oil price is $45 and the August 2016 futures price is $46. You bought the spot oil and closed out your futures position on 1 July 2016.
What was the effective price paid for the oil, taking into account basis risk? All spot and futures oil prices quoted above and below are per barrel.
