Hello everyone. I am 27 yo and have just started to invest early this month.

My idea is to invest 2000 CHF each month, for the next 15/20 years, mainly on $VWCE (-1,38 %) and $SMH (-2,05 %) but also in some single stocks. So far, I’ve invested a small portion on $MSFT (-1,53 %), $AMZN (-1,96 %) and $GOOGL (-2,9 %), and intended to add $NVDA (-2,11 %) or $TSM (-2,93 %) in the near future, even tho there’s already exposure to these companies on the ETFs I have invested.

My question is: is this a smart, relatively low risk strategy or would you make some changes? Does it make sense to invest 25/30% of my portfolio on single stocks or should I just stick with ETFs?

Thank you.
