ProShares Ultra QQQ (QLD) returns 1,695% in 10 years, outperforming Nasdaq-100 by leveraging 2x daily gains.

ProShares Ultra QQQ (QLD), a 2x leveraged Nasdaq-100 ETF, has returned 1,694.93% over the past decade, far exceeding the 519.84% gain of the non-leveraged Invesco QQQ Trust. The fund uses derivatives and leverage to double daily index returns, making it popular among retail investors during the Nasdaq's 2026 rally. While it closely tracks 2x returns over one year and year-to-date, volatility decay causes performance to lag a simple 2x multiple over five years. The fund benefits from long-term uptrends but can underperform in choppy markets due to daily reset mechanics. Investors should watch volatility levels and upcoming earnings cycles, as spikes in volatility could widen the performance gap.
