I am looking to improve the diversification of my portfolio and considering adding these three ETFs:

$XUCD (+1,49%) XUCD - Xtrackers MSCI USA Consumer Discretionary ETF

$IS3Q IS3Q - iShares Edge MSCI World Quality Factor ETF

$EXW1 (+0,86%) EXW1 - iShares EURO STOXX 50 ETF

I would like your advice on how to allocate my investment among them. Are these good choices, or am I overlapping exposures? Are there better alternatives to consider for further diversification?

Looking forward to your insights. Thanks for your help.
