The index funds that track the S&P 500 offer exposure to 500 of the top U.S. stocks, and the fund managers regularly rebalance the index, ensuring that laggards are removed and new winners are added. However, while the S&P 500 is a great long-term investment, there are ETFs that outperform it. Let's take a look at two that look poised to do just that.

As you can see from the chart below, the S&P 500 has nearly doubled the gains of the Russell 2000 since the end of 2022.Advertisement ^SPX data by YCharts That gap isn't surprising. After all, the current bull market has been led by the "Magnificent Seven," which has contributed most of the gains on the S&P 500. However, the iShares Russell 2000 ETF (IWM 1.06%), the biggest Russell 2000 ETF, looks like a good bet to beat the S&P 500 in 2026 for two main reasons. First, gains in a bull market tend to broaden as it matures, and, assuming the bull market continues, that seems likely to happen here. While the "Magnificent Seven" continue to deliver solid growth, smaller software companies and other stocks are starting to take advantage of AI, and that shift should benefit small-cap stocks. The other reason is that the Russell 2000 is now significantly cheaper than the S&P 500. The iShares Russell 2000 ETF now trades at a price-to-earnings ratio of just 18.3, compared to the Vanguard S&P 500 ETF at 28.7, meaning the IWM is nearly 40% cheaper than a comparable S&P 500 ETF. As valuation concerns increase, that discrepancy should also favor a rotation into small-cap stocks, helping them narrow the gap that's emerged over the last few years. 2. VanEck Semiconductor ETF One of the top-performing ETFs of the last decade is the VanEck Semiconductor ETF (SMH 3.61%). This year, the ETF is up 44% year-to-date, trouncing the S&P 500. Over the last decade, the VanEck Semiconductor ETF has jumped 1,180% as the semiconductor sector has boomed. However, the ETF looks like it's in position for another winning year as the fund isn't as expensive as you might think, trading at a P/E ratio of 39.7, which is comparable to other tech-heavy ETFs like the Vanguard Growth ETF and even the Invesco QQQ Trust. The VanEck Semiconductor ETF is stacked with the chip stocks leading the AI boom, led by Nvidia, Taiwan Semiconductor, and Broadcom, and those companies are delivering the kind of growth that justifies a premium valuation. Nvidia's revenue growth just accelerated to 62%, and TSMC is the world's dominant chip manufacturer. Broadcom may be the most diversified chip stock around, and its revenue growth improved to 28% in its most recent quarter.

Nvidia CEO Jensen Huang recently called out AI doubters, saying instead of a bubble, he sees a turning point in AI, where more companies take advantage of it. If that's the case, the SMH ETF looks like a good bet to outperform the index funds again.
