I understand that the ETFs SPY and VOO were created at different times and that their payout dates are different and due to that, it is possible that the dividends may vary a little bit.
In my logic though, over time, they should have the exact same amout of dividends (maybe with fees deducted) but what VOO doesn't pay out this quarter, it should be paying out next.
As VOO's fees are smaller than SPY, the dividend should even be higher than SPYs. But the dividend history of the two ETFs shows another picture (VOO's are always smaller by a significant amount):
Can somebody explain this?
