maturing in three months. However, the investor cannot lock in a real rate of return: There is
still some uncertainty about inflation.
By switching to long-term government bonds, the investor acquires an asset whose price
fluctuates as interest rates vary. (Bond prices fall when interest rates rise and rise when inter-

downs of the issuing companies.
Figure 7.1 shows how your money would have grown if you had invested $1 at the end of
1899 and reinvested all dividend or interest income in each of the three portfolios.^3 Figure 7.2
is identical except that it depicts the growth in the real value of the portfolio. We focus here
on nominal values.
Investment performance coincides with our intuitive risk ranking. A dollar invested in the
safest investment, Treasury bills, would have grown to $74 by the end of 2014, barely enough

purchasing power of returns
to investors.
