If I Could Invest in Just 1 ETF in 2026, Here's Where I'd Buy

In an investment commentary, The Motley Fool highlights the Invesco NASDAQ 100 ETF (QQQM) as a premier exchange-traded fund selection for long-term growth investors. The fund passively tracks the Nasdaq-100 index, delivering concentrated exposure to the top 100 non-financial companies listed on the Nasdaq Composite. Key heavyweights in the index include major technology market leaders such as Nvidia, Apple, Microsoft, Amazon, and Broadcom. The analysis notes that QQQM offers a lower expense ratio of 0.15% compared to the older Invesco QQQ Trust's 0.18%. Over the trailing five-year period, QQQM has outperformed broader market benchmarks, generating a total return of 98% with reinvested dividends against an 84% return for Vanguard's S&P 500 ETF (VOO). Because the Nasdaq-100 excludes slower-growth legacy sectors and financial firms while reconstituting annually, the author argues the index remains structurally positioned to outperform the broader S&P 500 despite experiencing higher market volatility.
