I think I've fallen into a bias. I haven't been running any ETF savings plans for a few months now because I'm waiting for a fall so that I can buy a bit more at once.
Specifically, I'm only talking about the three large ETFs in my portfolio: $VWRL (-0,61%)
$VUSA (-0,64%)
$HMWO (-0,7%)
(I do save the theme and sector ETF at the moment and buy individual stocks).
I assume that my approach is not expedient in the long term, as prices could often be higher than they are today, for example, even after a sharp fall in prices. What do you think? What percentage of my savings quota should I pump into these three ETFs? Add ETFs? Which ones? Why?
