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 (-0,8 %) and $SMH (-2,92 %) but also in some single stocks. So far, I’ve invested a small portion on $MSFT (-0,64 %), $AMZN (-1,14 %) and $GOOGL (+0,48 %), and intended to add $NVDA (-3,22 %) or $TSM (-3,24 %) 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.
