QQQ vs QQQM
Hello everyone, I plan on holding ETFs in a brokerage account for about 5-7 years (I also have other long term accounts). I planned initially on 65% in VOO and 35% in QQQ. However I recently discovered QQQM, which has a lower expense ratio. Which is better to use QQQ vs QQQM? I know QQQ has the long term history but is there any real difference for this use case?
