What Happens to 10Y-2Y Yield Spread When Small Caps Outperform Large Caps?
What happens when IWM beats SPY by 10%+? Fed-pivot rotation, regional banks (KRE) leading, Russell 2000 historically up 20-40% during 2-4 year cycles.
How 10Y-2Y Yield Spread Responds
Scenario Background
Small-cap outperformance versus large caps (IWM/SPY ratio rising) signals several potential regimes: Fed easing expectations, economic recovery, earnings-cycle acceleration, or rotation out of concentrated mega-cap leadership. Small caps are more cyclical, more domestic-focused, and more interest-rate sensitive than large caps.

Small caps (Russell 2000) have had several major outperformance cycles: 2003-2006 (recovery cycle, +75% outperformance), 2009-2011 (post-GFC recovery, +40%), 2016-2017 (Trump rally, +15%), and brief episodes in 2020 (+20% in 6 months post-COVID trough). Major underperformance cycles include 1998-2000 (tech bubble large-cap dominance), 2014-2024 (FAANG era), and 2022-2024 (high rates, strong dollar). Historical pattern: small-cap outperformance typically lasts 2-4 years once initiated, with total outperformance of 40-80% over the cycle. Entry signals include Fed first cut, yield curve steepening, and IWM/SPY ratio breaking multi-year trendlines.

- •Yield curve un-inverting (bull steepener)
