Hey, I’d love some advice on my investments. I recently opened an account with CS, and right now I’ve only started investing in QQQ. I was also considering adding VTI, VOO, and SCHB, but honestly I’m feeling overwhelmed by the amount of information out there. My goal is to invest for the long term, and I’d really appreciate some guidance on building a solid strategy. And what has worked for you the best? ETFS, mutual funds, etc?
Thank you in advance!!!
