Growth stocks should keep outperforming small caps because rising rates now hurt small caps far more. Large-cap and AI-linked growth companies are cash-rich and lightly financed, while about a third of Russell 2000 debt is floating-rate versus roughly 6% for the S&P 500. As hike expectations returned, small caps' lead over the S&P 500 shrank from about 11 points in June to about 2, and IWM tracks long bonds far more than QQQ. The ARKK/IWM ratio has reclaimed its rising 20-month Bollinger basis. x.com x.comÂ
