Suppose you buy 800 shares of Applied Materials Corporation at the beginning of year 1 for $45.50 per share. Applied Materials Corporation pays no dividends. The stock price at the end of year 1 is $49.50, the price is $57.50 at the end of year 2, and the price is $65.50 at the end of year 3. The stock price declines to $62.50 at the end of year 4, and you sell your 800 shares.

What is your geometric average return for the 4-year period? (Round your answer to 2 decimal places. Do not round intermediate calculations.)
