Your friend just bought a house for $400,000. He financed it using a $320,000 mortgage loan and a deposit of $80,000.

In the context of residential housing and mortgages, the 'equity' tied up in the value of a person's house is the value of the house less the value of the mortgage. So the initial equity your friend has in his house is $80,000. Let this amount be E, let the value of the mortgage be D and the value of the house be V. So ##V=D+E##.

If house prices suddenly fall by **10**%, what would be your friend's percentage change in equity (E)? Assume that the value of the mortgage is unchanged and that no income (rent) was received from the house during the short time over which house prices fell.

Remember:

### r_{0\rightarrow1}=\frac{p_1-p_0+c_1}{p_0} ###

where ##r_{0-1}## is the return (percentage change) of an asset with price ##p_0## initially, ##p_1## one period later, and paying a cash flow of ##c_1## at time ##t=1##.

**Question 322** foreign exchange rate, monetary policy, American and European terms

The market expects the Reserve Bank of Australia (RBA) to decrease the policy rate by 25 basis points at their next meeting.

Then unexpectedly, the RBA announce that they will decrease the policy rate by 50 basis points due to fears of a recession and deflation.

What do you expect to happen to Australia's exchange rate? The Australian dollar will:

The Chinese government attempts to fix its exchange rate against the US dollar and at the same time use monetary policy to fix its interest rate at a set level.

To be able to fix its exchange rate and interest rate in this way, what does the Chinese government actually do?

- Adopts capital controls to prevent financial arbitrage by private firms and individuals.
- Adopts the same interest rate (monetary policy) as the United States.
- Fixes inflation so that the domestic real interest rate is equal to the United States' real interest rate.

Which of the above statements is or are true?

**Question 338** market efficiency, CAPM, opportunity cost, technical analysis

A man inherits $**500,000** worth of shares.

He believes that by learning the secrets of trading, keeping up with the financial news and doing complex trend analysis with charts that he can quit his job and become a self-employed day trader in the equities markets.

What is the expected gain from doing this over the first year? Measure the net gain in wealth received at the end of this first year due to the decision to become a day trader. Assume the following:

- He earns $
**60,000**pa in his current job, paid in a lump sum at the end of each year. - He enjoys examining share price graphs and day trading just as much as he enjoys his current job.
- Stock markets are weak form and semi-strong form efficient.
- He has no inside information.
- He makes
**1**trade every day and there are**250**trading days in the year. Trading costs are $**20**per trade. His broker invoices him for the trading costs at the end of the year. - The shares that he currently owns and the shares that he intends to trade have the same level of systematic risk as the market portfolio.
- The market portfolio's expected return is
**10**% pa.

Measure the **net gain** over the **first** year as an expected wealth increase at the **end** of the year.

**Question 546** income and capital returns, interest only loan, no explanation

Which of the following statements about the capital and income returns of an **interest-only** loan is correct?

Assume that the yield curve (which shows total returns over different maturities) is flat and is not expected to change.

An interest-only loan's expected:

An equity index is currently at **4,800** points. The **1.5** year futures price is **5,100** points and the total required return is **6**% pa with continuous compounding. Each index point is worth $25.

What is the implied dividend yield as a continuously compounded rate per annum?

**Question 785** fixed for floating interest rate swap, non-intermediated swap

The below table summarises the borrowing costs confronting two companies A and B.

Bond Market Yields |
||||

Fixed Yield to Maturity (%pa) | Floating Yield (%pa) | |||

Firm A | 3 | L - 0.4 | ||

Firm B | 5 | L + 1 | ||

Firm A wishes to borrow at a floating rate and Firm B wishes to borrow at a fixed rate. Design a non-intermediated swap that benefits firm A only. What will be the swap rate?

**Question 807** market efficiency, expected and historical returns, CAPM, beta, systematic risk, no explanation

You work in Asia and just woke up. It looked like a nice day but then you read the news and found out that last night the American share market fell by **10**% while you were asleep due to surprisingly poor macro-economic world news. You own a portfolio of liquid stocks listed in Asia with a beta of **1.6**. When the Asian equity markets open, what do you expect to happen to your share portfolio? Assume that the capital asset pricing model (CAPM) is correct and that the market portfolio contains all shares in the world, of which American shares are a big part. Your portfolio beta is measured against this world market portfolio.

When the Asian equity market opens for trade, you would expect your portfolio value to:
