Re 1: this makes even less sense with ETFs than with shares.

Re 2: the two are based on different indices, aren't they?
@Moep why does it make even less sense? The Global accesses the Europe, among other things, as far as I can tell from the description.
@m0ody378 Shares and ETFs should be selected on the basis of expected returns and not when they pay dividends. And with an ETF, the decisive factor is what it contains. If you now select an ETF that pays out dividends in the months mentioned simply because it pays out dividends in these months, this may not fit in very well with your strategy. And since you are currently only investing in ETFs and accumulating your assets there, the effect will be even greater than it would have been with a single share.
