Suppose you buy 550 shares of Applied Materials Corporation at the beginning of year 1 for $44.25 per share. Applied Materials Corporation pays no dividends. The stock price at the end of year 1 is $48.25, the price is $56.25 at the end of year 2, and the price is $64.25 at the end of year 3. The stock price declines to $61.25 at the end of year 4, and you sell your 550 shares. What is your geometric average return for the 4-year period? (Round your answer to 2 decimal places. Do not round intermediate calculations.)
