I've been noticing something interesting lately when comparing leveraged ETFs to regular index funds, and it's worth paying attention to if you're thinking about your best long term etf strategy.

So here's the thing: UltraPro S&P 500 ETF has posted a 26% gain over the past year, which looks absolutely crushing compared to Vanguard S&P 500 ETF's 15% return. On the surface, that 10-plus percentage point difference might make you think you've found some kind of wealth-building cheat code. The "Ultra" branding even makes it sound like you're getting a pro-level investing tool. But that's exactly where you need to pump the brakes.

The core issue is how these leveraged ETFs actually work. UltraPro is designed to deliver three times the daily return of the S&P 500. So if the index rises 1%, the ETF targets a 3% gain. Sounds great until you realize something critical: that three-times multiplier resets every single day. The ETF's own documentation basically admits this is a problem, warning that over any holding period beyond one day, your actual returns can diverge significantly from that three-times target.

Here's where the math gets brutal. When markets pull back, leverage cuts both ways. If something drops 50%, it needs a 100% gain just to get back to breakeven. Early 2025 showed exactly this dynamic playing out. That market dip was absolutely vicious for UPRO holders, creating a massive hole that the ETF is still trying to climb out of. Meanwhile, the regular Vanguard fund took a much lighter hit. That's why the leveraged version only managed 26% instead of the 45% you might have naively expected from three times the S&P's performance.

The real lesson here is that leveraged ETFs and long-term investing are fundamentally misaligned. These funds are engineered for daily rebalancing, not buy-and-hold strategies. If you're the type who can stomach brutal drawdowns during bear markets, then maybe you have the constitution for it. But for most long-term investors looking for the best long term etf to actually build wealth steadily, the risk-reward profile just doesn't make sense.

The painful truth is that the leverage amplifies your losses on the way down far more than it boosts your gains on the way up when you're holding for years. If you're serious about long-term wealth building, a simple non-leveraged index fund probably deserves way more consideration than people realize.
