Consider the following information on large-company stocks for a period of years.
Series
Arithmetic Mean
Large-company stocks 14.1 %
Small-company stocks 16.4
Long-term corporate bonds 6.2
Long-term government bonds 6.1
Intermediate-term government bonds 5.6
U.S. Treasury bills 3.8
Inflation 4.0
1) What was the arithmetic average annual return on large-company stocks in nominal terms? (Do not round intermediate calculations. Enter your answer as a percentage rounded to 2 decimal places (e.g., 32.16).)
2) What was the arithmetic average annual return on large-company stocks in real terms? (Do not round intermediate calculations. Enter your answer as a percentage rounded to 2 decimal places (e.g., 32.16).)
Answer:
Part 1:
The arithmetic average annual return on large company stocks in nominal terms is 14.1%.
Part 2:
In order to calculate average annual return of large company stocks is real terms we will use the following formula
(1+N)=(1+R)(1+i)
R= real rate of return
N=nominal rate of return
i= inflation rate
putting values in the formula:
(1+0.141)=(1+R)(1+0.04)
1.141/1.04=(1+R)
1.097115=(1+R)
R=1.097115 - 1
R=0.0971 or 9.71%.
