$292 QQQM shares yield under 1%, making the main Roth IRA benefit tax-free capital appreciation rather than sheltering dividend income.
A $500,000 position faces only a modest annual dividend tax bill in a taxable account, but any sale can trigger 15% long-term capital gains tax for many investors, or 20% plus the 3.8% NIIT for top earners.
That tax wedge matters because QQQM returned 32.39% over one year and 103% over five years, so decades of compounding inside a Roth can avoid a large embedded gains bill.
The analysis argues investors should prioritize Roth space first for high-yield ordinary-income assets such as BDCs and mortgage REITs, then for growth ETFs like QQQM; it also flags early retirement Roth conversions for growth holdings.
