I just started investing last year. I’m trying to hit $100,000 this year. I have VOO as my core holding and a little bit of QQQM because my friend told me to get some. Is this a good portfolio or should I add international ETFs like VEA or VXUS. I heard about fund overlap and I’m not too sure if my two funds overlap that much but I think that with the performance and with my risk tolerance, I think it’s good for me. Thoughts? Thank you
