A $10,000 position in the Defiance Quantum ETF (NYSEARCA:QTUM) on the last trading day of 2025 was worth about $15,420 by the close on June 2, 2026, a 54.2% year-to-date move from a starting price of $109.44 to $168.76. Over the same stretch the S&P 500, as proxied by SPY, returned 11%, and the Nasdaq-100 via QQQ, the closest thing to a clean Magnificent 7 wrapper, returned 21%. A theme ETF beating the broad market by a factor of nearly five in five months is the kind of number that sends people to Google, and that is what you are doing here.

The $23.21 launch-window price sits well in the rear-view mirror, with the fund up 627% since inception and 99% in the trailing year alone.

The run is the product of the bench, with the equal-weighted structure preventing any one or two names from dragging the index higher Mag 7 style. That said, the pure-play quantum names inside QTUM have done staggering fundamental work this year, and they are the easiest place to start.
