But if you sold one year later for less then you paid, you wouldn't have made a 138% profit, that's how I see it...
Yes, you would - 138% of your initial investment:
0.00168724 * 52 = 0.08773648
0.08773648 / 0.06325322 = 1.3871 = 138.71%
I don't believe this is correct the dividend variable (0.00168724) increases/decreases... it's not finite. Truth be told, the yield is not accurate for this investment. Could be more could be less at the end of the year.
