Since its December 2006 launch by Invesco Ltd., the S&P 100 Equal Weight ETF has amassed a ten-year return of 271%, outpacing the traditional market-cap S&P 500 ETF’s 234% by a 37-percentage-point margin. Over the past 12 months, the fund gained 18.84% compared to 17.34% for its cap-weighted benchmark, and so far in early 2026 it has added 1.07% versus the benchmark’s 0.85%. By equally weighting the 100 largest S&P components, Invesco’s strategy caps any single holding at roughly 1% of the portfolio, systematically trimming stronger performers and reinvesting in laggards on a quarterly basis. This disciplined rebalancing mechanism has generated consistent outperformance over nearly two decades, making it a compelling alternative for investors seeking to reduce concentration risk in mega-cap technology names.

Data from early 2026 indicate a broadening of leadership beyond mega-cap technology, a dynamic that favors Invesco’s equal-weight approach. Small- and mid-cap benchmarks have outperformed their large-cap counterparts year to date, suggesting capital rotation into previously unloved segments. Historical analysis by Invesco shows that equal-weight versions of the S&P 500 have beaten cap-weighted versions by an average of 1.05% annually over multi-decade periods. Investors can monitor relative performance through index provider reports and real-time spreads between equal-weight and cap-weight ETFs to gauge whether this trend continues. Sustained market breadth expansion would likely enhance the ETF’s edge, reinforcing Invesco’s position as a leader in systematic, rules-based diversification strategies.
