CSPX and QQQ are mostly US, no?

and VWRA has less US but with the other 2, still US mostly.

Assuming equal weightage, I would recommend against it.

CSPX and QQQ overlaps too much. They overlap each other approximately 36% by market weight, and roughly 15% SPY is in QQQ and 77% of QQQ is also in SPY

CSPX then also overlaps VWRA by roughly 48% by market weight, ~5% with SPY, and 1% with QQQ.

You would be so insanely over-weighting some specific stocks unless its completely intentional and you know exactly what stock you are over weighting in, every month.

Perhaps you can share with us your investment philosophy for this portfolio to let us better understand it? Investment horizon, etc.

If you didn't own individual stock and make a portfolio of 1-30 stock, that means you wanted to diversify.

If you wanted to bet on the US, that the top 100 company will continue to grow, then QQQ is good enough, why SPY(CSPX)?

If you wanted to bet on the US, the top 500 company will continue to grow, you are more diversified, and their business being international in nature gives you pseudo-international exposure, then why QQQ?

If you are worried about US's growth, their ridiculous P/E ratio, and they may or may not receive a massive 20%+ pullback in near future, winners rotate to international stock for the next decade, and want to invest in 60US:40International ratio, and the next time it rotate again, it doesn't matter to you, because you hold all of them - then VWRA is perfect, why overweight US again with QQQ/SPY?

...et cetera.
