International Investing

Risks in International Investing
• What are the risks involved in investment
in foreign securities?
– Exchange rate risk
– Country specific risk
19-9
Exchange Rate Risk
• Variation in return related to changes in
the relative value of the domestic and
foreign currency
• Total Return is a function of
1. Investment return &
2. Change in the value of the foreign currency
19-10
Returns with Foreign Exchange
E1
1  r(US)  [1  r(For)] 
E0
r(US) = return on the foreign investment in
US Dollars
r(FM) = return on the foreign market in local
currency
E0 = original exchange rate
E1 = subsequent exchange rate

If you invest in a British Security and earn 10%,
find the return in US Dollars given:
Initial Exchange rate : £ = $2.00
Final Exchange rate: £$2.10
= $2.10

The Carry Trade
• Suppose the yen LIBOR = 0.24% and U.S.
$ LIBOR = 3.75%.
• An astute investor may borrow yen at the
yen rate, convert the borrowed funds to
dollars and invest at $ LIBOR.
• What can go wrong with this strategy?
– Default
– Yen increases in value by  3.75% - 0.24% =
3.51% or more.

Covered Interest Arbitrage (1)
U.S. interest rates are 6.15% and British interest
rates are at 10% when the exchange rate is
$2.00 / £. The one year forward exchange rate
for the pound is $1.95/£.
• How can you earn a riskless arbitrage profit
based on these quotes?
1.Borrow $1 at 6.15%: Will owe $1.0615 in one year
2.Convert $1 to pounds: $1 / $2.00/£ = £0.50
3.Invest £0.50 at 10%: Will yield £.50 x 1.10 = £0.55.
4.Sell pound forward at $1.95: £55 x $1.95 = $1.0725
5.Net: $1.0725 - $1.0615 = $0.011 / dollar
19-17
Covered Interest Arbitrage (2)
U.S. interest rates are 6.15% and British
interest rates are at 10% when the exchange
rate is $2.00 / £. The one year forward
exchange rate for the pound is $1.90/£.
• How can you earn a riskless arbitrage profit
based on these quotes?
1.Borrow £1 at 10%: Will owe £1.10 in one year
2.Convert £1 to $ at $2.00/£ = $2
3.Invest $2 at 6.15%: Will yield $2 x 1.0615 =$2.123
4.Buy pound forward at $1.90: Will cost £1.10 x $1.90
= $2.09
5.Net profit = $2.123 - $2.09 = $0.033

Conclusions
• A passive investment in all countries would not
have lowered risk at all during the recent crisis.
• Hedging currencies has little effect either. A U.S.
stock market crash appears to be a systemic
factor that cannot be diversified away from in a
crisis.
• Correlations are on the increase due to
globalization, nevertheless we still expect
modest international diversification benefits in
normal markets.

And Performance
Attribution
19-54
Performance Attribution
• The “Bogey” or benchmark
– EAFE index (non-U.S. stocks)
• Currency Selection
– Contribution to performance due to currency
movements
• Country Selection
– Contribution to performance due to choosing
better performing countries
19-55
Performance Attribution
• Stock Selection
– This ability is measured as the weighted
average of equity returns in excess of the
equity index in each country.
• Cash / Bond Selection
– Excess return due to weighting bonds and
bills differently from benchmark weights.
