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 (-0.62%) and $SMH (-0.36%) but also in some single stocks. So far, I’ve invested a small portion on $MSFT (+1.59%), $AMZN (+1.9%) and $GOOGL (+1.13%), and intended to add $NVDA (+2.32%) or $TSM (-0.93%) 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.
