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 (+0,94%) and $SMH (-0,06%) but also in some single stocks. So far, I’ve invested a small portion on $MSFT (+0,96%), $AMZN (+0,32%) and $GOOGL (-0,08%), and intended to add $NVDA (-2,35%) or $TSM (+0,5%) 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.
