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 (-0.53%) and $SMH (+0.73%) but also in some single stocks. So far, I’ve invested a small portion on $MSFT (-3.17%), $AMZN (-1.95%) and $GOOGL (+0.59%), and intended to add $NVDA (-3.33%) or $TSM (+2.72%) 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.
