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 (+1,12%) and $SMH (+2,51%) but also in some single stocks. So far, I’ve invested a small portion on $MSFT (+1,5%), $AMZN (+1,47%) and $GOOGL (+3,9%), and intended to add $NVDA (+2,2%) or $TSM (+1,08%) 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.
