Chapter 5, Problem 1CP
A portfolio of nondividend-paying stocks earned a geometric mean return of 5% between 1, January 1, 2010, and December 31, 2016. The arithmetic mean return for the same period was 6%. If the market value of the portfolio at the beginning of 2010 was $100, 000, what was the market value of the portfolio at the end of 2016? (LO 5-1)
