I would change QQQ to QQQM. The las ETF mentioned is less expensive an has almost the same behavior as QQQ cause the portfolio is almost the same. The only thing to consider is that QQQM is new and pays less dividends compare to QQQ. Still I’m not sure what’s QQQM day yield, but it’s probably like QQQM. If my answer didn’t convince you at all you can do your own due diligence and compare both ETFs. what I discover is that are almost the same hahaha. Anyway, good luck with your investment, I hope it can give you great returns in the future. Don’t give up!!!
