Portfolio Theory and International Securities Markets Short Review of Portfolio Theory Diversification and Globalization
The World Equity Market • World equity markets grew rapidly from 1992 to 2006 • Market capitalization (value) of developed countries stock markets was $33 trillion at year end 1999. By year end 2002 it was $20.9 trillion • By 2005 the developed markets had recovered and their market capitalization reached $36.5 trillion
The World Equity Market • Markets fluctuate with economic activity • Over time markets recover with the economy • World markets had a strong recovery in 2003 and continued into 2007. • Developed world securities markets continue to expand • Major growth also in the “emerging” markets • Argentina - Brazil - China – Taiwan -- Mexico
Emerging Markets Share2002 and 2005 • 2002 2005 • Mideast and Africa 18% > 31% • South Asia 12% > 14% • East Asia 48% < 29% • Eastern/Central Europe 7% > 11% • Latin America 15% = 15%
Diversification Benefits • Invest in foreign markets fordiversification • Foreign markets do NOT move in harmony with each other • Diversified portfolio from many countries is less volatile than domestic portfolio - could even have a higher rate of return As the world markets become more global, returns between countries may become more harmonized.
Diversification Benefits cont. • Correlation between the historical returns of different countries is less than 1.0 • Richard Roll: Most significant factor relating to the size of the market decline in each country was the beta, β, of that market to the world market index • No country continually outperforms the others on an annual basis
Developing an Efficient Portfolio Consider large number of portfolios based on • Expected value • Standard deviation • Correlations between the individual securities • A portfolio of 14 to 16 stocks is fully diversified • Portfolio theory was developed by Professor Harry Markowitz (1950s). Won the Nobel prize in 1990 for this work
Efficient Frontier Line • 4 points out of 8 possibilities lie on the frontier • ACFH delineates the efficient set of portfolios • It is efficient because portfolios on this line dominate all other attainable portfolios ACFH line: efficient frontier because portfolios on it provide best risk-return trade-off
Capital Asset Pricing Model (CAPM) • Professor Sharpe advanced efficient portfoliosto capital asset pricing model • Assets value based on risk characteristics • CAPM takes off where efficient frontier stops • Introduce • New investment outlet • Risk-free asset (RF)
Risk-free (RF) Asset • Has no risk of default • Standard deviation of zero (-0-) • Lowest/safest return • U.S. Treasury bill • U.S. Treasury bond Zero risk CAPM combines risk-free asset & efficient frontier
Capital Market Line (CML) • RFMZ line capital market line (CML) • Formula for the capital market line See next slide Kp = Expected value of the portfolio σM = Market standard deviation RF = Risk-free rate KM = Market rate of return σP= Portfolio standard deviation
Return on an Individual Security Ki = Stock return, dependent variable, Y-axis ai (alpha) = Line intersects vertical axis bi (beta) = Slope of the line KM = Market return, independent variable, X-axis ei = Random error term ai + biKM : Straight line ei = Deviations, nonrecurring movements
Beta Beta is a measure of Risk relative to a market index. In the U.S. it is usually measured over 60 months against the broad Standard and Poor’s 500 Index.

Return Potential in International Markets + Less risk exposure Possible higher returns International diversification Several countries had long-term growth rates superior to U.S. in terms of real GDP: • Norway • Singapore • China
Return Potential in International Markets • Many countries are highly competitive in • automobiles, steel, & consumer electronics • Germany • Japan • France • Canada Enjoy higher individual savings rates than U.S. 3. Capital formation and potential investment opportunity

Current Quotations on Foreign Market Performance • Track performance of selected world markets • 1st index EAFE =Europe, Australia, FarEast • Quotes are in local currencies & in U.S. $ • U.S. investors compare returns in U.S. against an investment in U.S. stock market www.msci.com Instructions to navigate msci website: on Power Point tool bar click View, choose Notes Page
Other Market Differences • Culture • Willingness to take risk • Desire for dividend income versus growth in share value • Number & type of companies available to stockholders • Bureaucratic differences
Other Market Differences cont. • Accounting conventions • Government regulation of markets • Problem with comparing P/E ratios: Earnings calculated differently according to local or regional accounting
Currency Fluctuations and Rates of Return • Tracking foreign markets requires adjustments • Reported returns adjusted for foreign currency effects • How important is the foreign currency effect in relation to overall return performance in foreign currency? • Do foreign exchanges overpower actual return on investments in foreign countries?
Currency Fluctuations and Rates of Return • Foreign currency effect is about 10 to 20% as significant as the actual return performance in the foreign currency • If dollar is rising/falling rapidly over a short period the impact can be much greater
Currency Fluctuations and Rates of Return • Investment in Switzerland: 10% return • CHF declines by 5% against U.S. $ • CHF profits are worth less in $ Gain on investment: • 110% (Investment with 10% profit) • Adjusted value of CHF relative to U.S. $ • = 0.95 =1.00 - 0.05 decline in currency • 104.5% (= 110 x 0.95) of original investment • Actual return in U.S. $ 4.5% insteadof 10% Swiss franc = CHF
Currency Fluctuations and Rates of Return • Examine currency effects in Sweden YTD • Return in local currency 4.58% (3rd column) • Return in U.S. $............. 6.31% (7th column) • Change in $/SEK made a positive return in kronor become a negative return in U.S. $ See Table 19-8 next 2 slide Swedish currency Krona (pl. Kronor) symbol SEK
Currency Fluctuations and Rates of Return Computed returns: • 104.58% (Investment with 4.58% profit) • (Adjusted value of the SEK to U.S. $) 0.896 (1.000 - 0.104 decline in currency) • 93.7% (= 104.58 x 0.896) of original investment See Table 19-8 next slide
Other Obstacles to International Investments • Political Risks • Tax Problems • Lack of Market Efficiency • Administrative Problems • Information Problems • Corruption
Political Risks • Danger of nationalization of foreign firms • Restriction of capital flows to investors • Violent overthrow of political party in power • Not meeting their foreign debt obligations • Check the political/economic climate
Tax Problems • Foreign countries may impose 15 to 30% withholding tax against dividends or interest paid to nonresidents • Tax-exempt U.S. investors can secure exemption or rebate • Taxable U.S. investors can claim a U.S. tax credit for taxes paid in foreign countries • Inconvenience rather than loss of funds
Lack of Market Efficiency • U.S. capital markets the most liquid & efficient in the world • Investors accustomed to trading on NYSE will find it difficult to adjust to foreign markets • Larger spread between bid (sell) & ask (buy) price • Difficulty executing large transaction • Higher commission rates

Administrative Problems • Adjusting to various local systems For example, • Hong Kong, Swiss, & Mexican stock markets settle accounts one day after the transaction • London: two-week settlement • Different administrative procedures add extra difficulty in executing trades • Avoid these difficulties by going through mutual funds and other investment outlets
