Question: what was the mathematical range for all four groups in 12/2010 , assuming investments of $ 100 initially in 2008?
Evidence:
table_1: the valero common stock of 12/2007 is $ 100.00 ; the valero common stock of 12/2008 is $ 31.45 ; the valero common stock of 12/2009 is $ 25.09 ; the valero common stock of 12/2010 is $ 35.01 ; the valero common stock of 12/2011 is $ 32.26 ; the valero common stock of 12/2012 is $ 53.61 ;
table_2: the s&p 500 of 12/2007 is 100.00 ; the s&p 500 of 12/2008 is 63.00 ; the s&p 500 of 12/2009 is 79.67 ; the s&p 500 of 12/2010 is 91.67 ; the s&p 500 of 12/2011 is 93.61 ; the s&p 500 of 12/2012 is 108.59 ;
table_3: the old peer group of 12/2007 is 100.00 ; the old peer group of 12/2008 is 80.98 ; the old peer group of 12/2009 is 76.54 ; the old peer group of 12/2010 is 88.41 ; the old peer group of 12/2011 is 104.33 ; the old peer group of 12/2012 is 111.11 ;
table_4: the new peer group of 12/2007 is 100.00 ; the new peer group of 12/2008 is 66.27 ; the new peer group of 12/2009 is 86.87 ; the new peer group of 12/2010 is 72.84 ; the new peer group of 12/2011 is 74.70 ; the new peer group of 12/2012 is 76.89 ;
