Morgan Stanley analysts, including Michael Wilson and Andrew Pauker, argue small-cap stocks should continue beating larger peers. The index tracking shares with market caps between $250 million and $2 billion is up over 6% this year, while the S&P 500 has gained just over 1%. Their case rests on improving fundamentals.

The analysts point to earnings growth hitting its strongest level since 2022. A key metric, the earnings revisions breadth, shows more analysts are raising estimates for small-caps than cutting them. This positive trend has broken a multi-year downtrend in relative performance, suggesting market-wide optimism is shifting toward smaller companies.

This outperformance is notable despite fading bets on more Federal Reserve rate cuts. The correlation between small-cap returns and real interest rates is near zero, meaning earnings now drive performance more than borrowing costs. While rate sensitivity is a traditional concern for small-caps, their recent resilience signals a focus on profit momentum over monetary policy.

Looking ahead, the political backdrop adds uncertainty. President Trump has suggested replacing Fed Chair Jerome Powell, with former Governor Kevin Warsh seen as a front-runner. Morgan Stanley notes Warsh is considered more hawkish, but small-caps have thrived regardless, suggesting fundamentals are the primary driver for now.
