The article discusses the ProShares S&P 500 Dividend Aristocrats ETF (NOBL), which tracks companies with at least 25 consecutive years of dividend growth. The author notes that NOBL has significantly underperformed the broader market due to its lack of exposure to the artificial intelligence (AI) sector, which has driven recent market gains. The article highlights that NOBL's portfolio excludes major AI beneficiaries like Nvidia, Microsoft, and Apple, as these companies do not meet the dividend growth requirement. The author argues that while NOBL offers stability and consistent dividends, its exclusion of high-growth AI stocks has resulted in a "price of sitting out AI" in terms of relative performance. The piece concludes by suggesting that investors in NOBL must accept this trade-off between dividend reliability and missing out on AI-driven market rallies.
