Russell 2000 short interest near 8% of shares outstanding
Small-cap index short interest has climbed to about 8.0% of shares outstanding, the highest level since at least 2019 and nearly double the share seen at the start of 2025, versus roughly 3.5% ahead of the 2022 bear market.
Market response
Large-cap indices remain near records while breadth and small caps stay the skeptic lane — watch whether shorts cover into year-end or cap-weight leadership cracks first.
Why it matters
If mega-cap AI and hyperscaler capex keep winning, crowded Russell shorts can stay painful; if credit or housing (7.56% 30Y fixed mortgage rate) bites, small-cap positioning may flip faster than the headline index.
