Returns Economics 71a: Spring 2007 Lecture notes 3.2 (extra)
Goals • Capital gains and income • Inflation and real returns • Expected or required returns • Returns in other currencies
What is a Return? • Stock held from time t to t+1 • Pays dividend during this time of d(t+1) • Why is this sensible? • Increase of 1 dollar after investment t to t+1
Two Parts to a Stock Return = (capital gain) + (dividend yield)
Two Parts of a Bond Return = (capital gain) + (Interest)
Goals • Capital gains and income • Real returns • Expected or required returns • Returns in other currencies
Real Returns • Nominal return • Return before inflation adjustment • Real return • Return after adjusting for inflation
Real Return (example) • $1 in the bank buys how much more bread in the future • Nominal Interest Rate = 10% = RF = “risk free” • Inflation rate = 5% = p • Price of bread = $1 • $1 buys 1 loaf today • In one year • Money = $1.10 • Price of bread = $1.05 • Loaves tomorrow = 1.10/1.05 = 1.048
Risk Free Return (Interest) • Interest rate = real interest + Inflation premium
Real Interest Rate • Nominal interest rate = 20% per year • Inflation = 15% per year • Real interest rate = 20%-15%=5% • Important • The return on your funds is reduced by inflation • Should always consider the inflation adjusted change for any asset
Goals • Capital gains and income • Real returns • Expected or required returns • Returns in other currencies
Expected or Required Returns • Amount investors expect to receive on an investment • Three parts • Real risk free return • Inflation premium • Risk premium • Compensation for risk (difficult to estimate)
Goals • Capital gains and income • Real returns • Expected or required returns • Returns in other currencies
Exchange Rates • E($/euro) = U.S. dollars required to purchase 1 euro • Price($) = Price(euro)*E($/euro)
Exchange Rate Risks Price and Dividends in Euros
Exchange Rate Risks(Dividend = 0, stock price 100->110, $/euro 1 -> 0.8)
Returns in US dollars • ($/euro) goes down • Decreases foreign investment values (in dollars) • Price of foreign goods falls (in dollars) • ($/euro) goes up • Increases foreign investment values (in dollars) • Price of foreign goods rises (in dollars)
