Answer 1

Answer 1.6:

Data given:

The percentage change in the Russell 2000 Index of the stock prices of 2,000 small companies was +18.33% in 2004 and +4.55% in 2005.

Geometric rate of return = ?

As we know, the formula for computing the geometric rate of return is given as -

where - rate of returns

n - number of periods

Using the above formula, we can compute the geometric rate of return for the given scenario as -

     

     

Thus, the geometric mean rate of return is approximately 11.23% .

Hence, the correct option is (d) .
