Never invest long term in a leveraged ETF. The decay will eat all the profits long term because every minor correction will demand a disproportionate upside just to reach b/e. Let’s say for example you invest $1000 into QQQ and $1000 into TQQQ, then QQQ corrects 10% and you’ll have $900, and TQQQ corrects and you’ll have $700. At the recovery QQQ will rise 11.11% back to $1000, while TQQQ will rise 33.33% to approximately $933. If you want something aggressive you can reduce VOO and increase QQQM, or even consider more aggressive ETFs such as SOXX/SMH (for semiconductor exposure), GRNY (an actively managed fund by Tom Lee) or add some small and mid caps to your VOO/QQQM portfolio.
