Selected Investment Indexes Chapter 11 Chapter 11: Selected Investment Indexes
Background • Chapter investigates domestic and international indexes for stock and bond markets • Objectives include using indexes to • Rapidly gain knowledge • Confront theories with facts • Investigate market inter-relationships • Allocate assets • Examine overall economic relationships Chapter 11: Selected Investment Indexes
Long-Term Returns for Major Asset Classes • We’ll examine seven U.S. price indexes: • Large company stocks (S&P500) • Long-term U.S. government bonds • Intermediate-term U.S. government bonds • U.S. Treasury bills • Small company stocks • Long-term corporate bonds • Inflation (percentage change in CPI)
Long-Term Returns for Major Asset Classes • Examine indexes because individual security prices reflect non-systematic events, whereas price indexes contain many different securities—a diversified portfolio • Allows examination of meaningful trends and relationship between categories of investments Chapter 11: Selected Investment Indexes
Ibbotson’s Seven Basic Indexes • Large company stock index • Measured by S&P500 Stocks Composite Index, using total returns • Annual compound growth of 11.3% from 1925-1999 • Dividends represent 4.5% and capital gains 6.6% • Annual returns fluctuated from a low of –43.3% (in 1933) to a high of 54.0% (in 1934) Chapter 11: Selected Investment Indexes
Ibbotson’s Seven Basic Indexes • Small company stock index • Annual compound growth of 12.6% from 1925 to 1999 • Range from low of –58.0% (in 1937) to 142.9% (in 1933) • The small stocks index shows that investors were rewarded with a high total return as compensation for the unique risk involved with small stock investing Chapter 11: Selected Investment Indexes
Ibbotson’s Seven Basic Indexes • Long-term corporate bond index • Annual compound growth rate of 5.6% • Range of –8.1% (in 1969) to 42.6% (in 1982) Chapter 11: Selected Investment Indexes
Ibbotson’s Seven Basic Indexes • Long-term government bond index • Annual compound growth rate of 5.1% • Range from –9.2% (in 1967) to 40.4% (in 1982) • Interestingly, the coupon income component of the Treasury bond’s total return is > 100%, as the price declines exceeded the price increases Chapter 11: Selected Investment Indexes
Ibbotson’s Seven Basic Indexes • Intermediate-term government bond index: • Annual compound growth rate of 5.2% • Range from –5.1% (in 1994) to 29.1% (in 1982) • Return from income was 4.7% of the 5.2% total return Chapter 11: Selected Investment Indexes
Ibbotson’s Seven Basic Indexes • U.S. Treasury Bill index: • Annual compound growth rate of 3.8% • Range from 0% (in 1938-1940) to 14.7% (in 1981) • Over the 74-year sample period, T-bill returns exceeded inflation rate by 0.6% (or 60 basis points) Chapter 11: Selected Investment Indexes
Ibbotson’s Seven Basic Indexes • Inflation in the U.S. • Compound annual inflation rate of 3.1% • Range from –10.3% (in 1932) to 18.2% (in 1946) • Deflation occurred during the Depression from 1926-1933 Chapter 11: Selected Investment Indexes
Asset Class Annual Return Ending Wealth S&P 500 11.3% $2,845.63 Small company stock index 12.6% $6,640.79 Long-term corporate bond index 5.6% $56.38 Long-term government bond index 5.1% $40.22 Intermediate-term govt. bond index 5.2% $43.93 U.S. Treasury Bills 3.8% $15.64 Inflation 3.1% $9.39 Wealth Accumulation • If you had invested $1 in the following from end of 1925 to end of 1999 it would have increased to • Method of computation is (1 + return)n = Ending Wealth
Wealth Accumulation • Inflation means that the purchasing power of $1 is not the same from year-to-year (it decreases) • $1 of purchases made in 1925 would cost $9.39 by 1999 • $1 x (1 + 0.030728)74 = $9.39 • Therefore, the $2,845.63 after adjusting for inflation is only worth ? in real terms • $2,845.63 $9.39 = $303.05 (or 1.113469 1.030728) • While the accumulated real wealth is much lower than the nominal wealth, it is still an impressive number Chapter 11: Selected Investment Indexes
Risk Premium Type Definition Arithmetic Mean Risk Premium Small company premium Small Cap Return – Large Cap Return 17.6% - 13.3% = 4.3% Equity premium Large Stock Return – T-Bill Return 13.3% - 3.8% = 9.5% Horizon (Time) premium T-Bond Return – T-Bill Return 5.9% - 3.8% = 2.1% Inflation premium T-Bill Return – Inflation Rate 3.8% - 3.2% = 0.6% Risk and Return • Risk premiums represent the additional return expected by investors when they select a certain class of asset; equities compared to bonds, for instance
Reinvestment Return • Bonds that pay a coupon have 3 different types of income • From cash flows • From capital appreciation (or depreciation) • From reinvestment • When calculating returns over multiple time periods, it is conventionally assumed that cash flows are reinvested as soon as received (reinvestment income) • Can represent a sizable portion of return, especially for bonds Chapter 11: Selected Investment Indexes
October 19, 1987 • On October 19, 1987 the international stock market crashed, suffering a 22.6% loss in the DJIA • However, the stock market index ended the 1980s with an overall gain • Therefore, large short-run price fluctuations may not be that important in the long-run Chapter 11: Selected Investment Indexes
Serial Correlation • Serial correlation (or autocorrelation) • Measures the extent to which the values in one series are related to leading or lagged values in the same time series of data • Positive serial correlation occurs when data moves in trends • Negative serial correlation occurs when data experiences reversals • Random numbers have a zero serial correlation Chapter 11: Selected Investment Indexes
Serial Correlation • Observations • Inflation moves in trends as do Treasury bills • The absence of serial correlation in the stock and long-term bond indexes suggests that these returns tend to fluctuate in a random fashion, making them difficult to forecast • Technicians disagree with this finding and claim they can discern useful patterns
Real Returns • Real returns represent nominal returns less the inflation premium
Ibbotson: Problem 11-3 • $1,000 invested for 10 years at 17.8% • Inflation averaged 3.2% for 10 years • Nominal portfolio value: • $1,000(1.178)10 = $5,145.80 • Real portfolio value: • $5,145.80/(1.032)10 = $3,755.40
Ibbotson: Problem 11-6 • $40,000 saved in eight years • Inflation expected at 4% per year • Inflation-adjusted value: • $40,000/(1.04)8 = $29,227
