I can't figure out what the difference is between them.
QQQ is a fund that tracks one of them, but I don't know which. It apparently all 3 match very closely:
https://seekingalpha.com/symbol/XNDX/charting?compare=XNDX,Q...
QQQ's "1-Year Daily Total Return" is -6.78% and its "1-Year" "Trailing Returns" "Monthly Total Returns" is 9.54%. How come those numbers are so different? Shouldn't they be essentially the same?
These other sites say QQQ's "1 Year Return" is -2.78%.

I don't understand any of these numbers. How can this stuff be so contradictory?
XNDX = a total return index tracks the price + reinvests all dividends back in to the index [2]
