L&G Ecommerce Logistics ETF

Hello dear Gequin Community,

I am currently working on restructuring my portfolio. Historically, I currently have a few funds and a number of individual shares.

I would like to switch the funds to ETFs and continue to save in them.

Classically, I would now select the following ETFs:

$VWCE (+0,05 %) / $VHYL (+0,08 %) and $VFEG (-0,22 %)

Now my little thought experiment: Why should I limit myself to three ETFS when I could spread the whole thing much more widely? I have also thought about something like this (with smaller sums, of course):

$WELS (+0,33 %)

$ECOG (-0,34 %)

$EXH5 (-0,15 %)

$CHIP (-0,21 %)

$DFEN (-0,06 %)

$XDWF (+0,03 %)

$RBOT (-0,37 %)

$XAIX (-0,43 %)

$IH2O (+0,31 %)

$WELW (-0,03 %)

Of course I have a few duplications here, but I am much more differentiated.

Does this approach make sense in your eyes or is it a modest idea?
