Question: what is the roi of s&p500 if the investment takes place in october 2007 and it is sold in october 2010?
Evidence:
text_2: the comparison assumes $ 100 was invested on october 28 , 2007 in applied common stock and in each of the foregoing indices and assumes reinvestment of dividends , if any .
table_2: the s&p 500 index of 10/28/2007 is 100.00 ; the s&p 500 index of 10/26/2008 is 63.90 ; the s&p 500 index of 10/25/2009 is 70.17 ; the s&p 500 index of 10/31/2010 is 81.76 ; the s&p 500 index of 10/30/2011 is 88.37 ; the s&p 500 index of 10/28/2012 is 101.81 ;
