RE:Does this look less "mumbo jumbo"? If you are not good at math.....
Going from $2.00 to $2.20 is a gain of $0.20. What Percentage is that?
$2.00 x ? = $0.20
? = 0.20 / 2 = 0.1
Going from $2.20 to $2.00 is a loss of $0.20.
$2.20 x ? = $0.20
? = 0.2 / 2.2 = 0.09 approx. and since it is a loss it's negative. -0.09
Now ETF is double..... so 0.20 and -0.18
