The iShares Core Dividend Growth ETF has materially outperformed the ProShares S&P 500 Dividend Aristocrats ETF over the comparison windows cited through October 7, 2026. A hypothetical $100,000 invested ten years earlier grew to $351,740 in DGRO, including dividends, versus $254,580 in NOBL. The 97.16-percentage-point gap is large enough to demand an explanation, but it is not proof that one fund will dominate the next decade.
Different rules create different portfolios
DGRO and NOBL are both dividend strategies, yet they do not solve the same portfolio problem. ProShares says NOBL follows the S&P 500 Dividend Aristocrats Index, which requires at least 25 consecutive years of dividend growth and uses an equal-weighted approach. That discipline emphasizes business durability and prevents the biggest companies from automatically dominating the portfolio.
iShares describes DGRO as a broad U.S. equity fund focused on companies with a history of dividend growth. Its underlying index applies dividend, payout and quality screens without demanding the same multidecade record, then weights constituents by their share of the index's aggregate dividend dollars. The looser tenure requirement gives DGRO access to large companies that are still credible dividend growers but have not yet qualified as Aristocrats, while dividend-dollar weighting lets larger payers carry more influence than they would in an equal-weighted portfolio.
That distinction helps explain the result. The cited total returns show DGRO ahead by 32.2 percentage points over five years and 5.61 points over one year, in addition to the ten-year lead. NOBL's equal weighting spreads company-specific risk, but it also trims winners at rebalances and gives slower-growing constituents the same starting weight as faster-growing ones. DGRO's broader opportunity set has been better aligned with a market led by large, profitable growth companies.
What the backward-looking numbers miss
Past leadership can reverse when market breadth changes. Equal weighting may become more valuable if returns spread beyond the largest companies or if expensive growth stocks underperform. NOBL's long dividend histories may also appeal to investors who value consistency through recessions more than maximum participation in a concentrated bull market.
Fees, turnover, yield, sector exposure and tax consequences should be compared alongside total return. Selling a long-held NOBL position in a taxable account may create a capital-gains bill that takes years to recover through incremental performance. Redirecting new contributions can be more efficient than an immediate wholesale switch.
The decision hinge is therefore mandate fit, not the headline dollar gap. DGRO has delivered the stronger combination of dividend growth and capital appreciation in the measured period. NOBL remains a more explicit bet on dividend longevity and equal-weight diversification. Investors should compare current holdings, valuation exposure and tax cost before assuming the previous decade's market regime will repeat.
