Increase allocation to QQQ for long-term growth by reducing exposure to individual stocks.

I would invest more in VOO, more in QQQ or QQQM if it's for the long term,

I would reallocate that money a bit, increasing the investment in QQQ and VOO, and reducing it in individual stocks.

if I were you, I'd consider withdrawing $7,500 of it and putting it into a Roth IRA, investing it in funds like VOO, QQQ, AIQ, and other instruments that tend to appreciate over the long term.
