For most of 2026, the story was simple and almost too clean: small caps finally outperformed, the equal-weight index beat the cap-weight index, and institutional money rotated out of the Magnificent Seven into domestic, rate-sensitive, real-economy companies.
The Russell 2000 outperformed. The thesis held. Then Kevin Warsh walked into his first press conference on June 17 and the math got a lot more complicated.
In early 2026, the equal-weighted S&P 500, tracked by the Invesco S&P 500 Equal Weight ETF (RSP), outperformed the traditional, market-cap-weighted S&P 500. That divergence was one of the clearest indications of a broader rotation in sentiment and capital flows that investors haven’t seen in years.
The structural case for that rotation was real. Nearly 40% of Russell 2000 constituent companies carry floating-rate debt. The reduction in borrowing costs acted as an immediate injection of liquidity into these balance sheets, directly boosting earnings power that had been suppressed for years.
The Federal Reserve’s 175 basis points of cuts from late 2024 through 2025 take 12–18 months to filter through small-cap balance sheets — meaning the spring and summer of 2026 are precisely when the earnings benefit of lower floating-rate interest expense begins appearing in reported financials. For the first time in three years, small-cap companies are not fighting an interest rate headwind — they have a tailwind.
That was the thesis. Here’s the complication.
What Warsh Changed
The Federal Reserve held its target federal funds interest rate in the 3.50%–3.75% range at the June 2026 meeting. Elevated inflation, primarily stemming from higher energy prices, has increased investor expectations for higher policy rates later this year, in contrast to the gradually decelerating inflation prior to the conflict in Iran paired with previous expectations for rate cuts.
Large stocks, represented by the S&P 500, fell 1.2% on the day of the decision, while small stocks fell 0.8%, represented by the Russell 2000. Small caps fell less. Interesting. But the direction was the same.
The floating-rate debt that gave small caps an earnings tailwind when rates were falling becomes a headwind if rates go back up. Market pricing now assigns a high probability of a rate hike by December 2026 — a dramatic shift from the multiple cuts that were priced at the start of the year. That’s not a minor adjustment. That’s a full narrative reversal.
What Still Works
Not everything breaks if rates go higher. The valuation gap is still there. At the start of 2026, the Russell 2000 forward P/E was approximately 18x versus 26x for the S&P 500 — a 30% discount at a 30-year extreme. Even after the Great Rotation rally, the gap remains historically wide. The normalization trade has room to run.
Bank of America forecasts small-cap earnings to grow by 17% in 2026, outpacing the 14% expected for large caps. If that holds, quality small caps can earn their way through a modest rate increase. The question is what happens to the lowest-quality names in the index that were being kept alive by cheap floating debt.
During the one-year period ending on rank day for the Russell reconstitution, the Russell 2000 outperformed the Russell 1000, reflecting renewed strength among smaller companies. The total market capitalization of the Russell 2000 increased from $2.7 trillion at the 2025 reconstitution to $3.5 trillion in 2026. Real money, real growth. This isn’t a momentum fiction.
The Rotation Is Not Dead. It’s Narrowing.
The broadening-out trade doesn’t need rates to fall further. It needs earnings to hold and the economy to stay out of recession. Guggenheim sees real GDP growth holding around 2% in 2026, underpinned by robust AI capital expenditures and near-term fiscal tailwinds.
In that environment, the winning small-cap names aren’t the highly leveraged ones. They’re the domestically focused industrials, regional banks with strong deposit franchises, and companies with pricing power that benefited from reshoring and OBBBA provisions regardless of what the Fed does next. Industrials are still supported by increased capital spending in key growth areas like electricity capacity, construction around AI infrastructure, defense, and energy.
The Great Rotation worked. What comes next is more selective. That’s not a bad thing for active investors. It just means the index trade is harder and the stock-picking trade is more interesting.
The July 28–29 Fed meeting is the next real test. Watch the inflation data between now and then closely.
