The Dow 10 Strategy” maintains a portfolio of the 10 highest yielding Dow Jones industrial stocks. Consider the data as per table, for the 25 years.

  1. Compute the average annual returns for the Dow Jones Portfolio and the Dow 10 Strategy portfolio. Comment about the reward.
  2. Compute the sample standard deviation for each portfolio. Comment about risk.
  3. Compute the geometric mean Xg of 1+Rj for each portfolio. Compute (Xg)-1. What does this last number represent?
  4.   is the equation relating least squares slope , Correlation  r and sample standard deviation. Compute the r for Dow 10 versus Dow Jones.

Note:   Use of calculators and computers is highly recommended.

I have calculated the answers using Excel since Note says Use of computer is recommended (You can use Formulas)

a) Average Annual Return =AVERAGE(all return values selected)

for Dow Jones Portfolio = 14.04%

and the Dow 10 Strategy portfolio = 19.38%

Comment:- Dow 10 Strategy Portfolio has higher Average Annual return thus more rewarding.

b) Standard Deviation =STDEVP(All return values selected)

for Dow Jones Portfolio = 0.166

and the Dow 10 Strategy portfolio = 0.158

Comment:-  Dow 10 Strategy Portfolio has lower Standard Deviation thus Less Risky.

c) Geometric Mean (Xg) of (1+Rj)

Add 1 to all returns, it will look as:-

1973 86.84% 103.96%
1974 76.79% 99.28%
1975 144.48% 156.03%
1976 122.75% 134.93%
1977 87.24% 98.25%
1978 102.62% 100.12%
1979 110.52% 112.99%
1980 121.45% 127.23%
1981 96.60% 107.73%
1982 125.84% 126.05%
1983 125.68% 138.75%
1984 101.07% 105.75%
1985 132.83% 129.40%
1986 126.96% 134.79%
1987 106.00% 106.07%
1988 115.97% 124.33%
1989 131.74% 125.66%
1990 99.39% 92.43%
1991 123.99% 134.02%
1992 107.37% 107.79%
1993 116.74% 126.91%
1994 104.94% 104.05%
1995 136.47% 136.51%
1996 128.58% 128.18%

Now type in Excel =GEOMEAN( and select this Data Range)

you will get

for Dow Jones Portfolio = 112.76%

and the Dow 10 Strategy portfolio = 118.34%

Comment :- Xg -1 of Dow Jones Portfolio = 112.76% -1 = 12.76%

Xg -1 of Dow 10 Strategy Portfolio = 118.34% -1 = 18.34%

This Number Indicates Return of the respective Portfolios over 25 years.

Average Annual Return ignores Compounding of Return, However this return (Calculated using Geometric mean) takes into consideration Compounding of return as well.

d) Correlation (r) for Dow 10 versus Dow Jones=

=CORREL(All return values of Dow 10 , All return values of Dow Jones)

= 0.9
