The Russell 2000's Resurgence: Small-Cap Value Rotation and Rate-Cut Optimism Drive Momentum

The Russell 2000, a benchmark for U.S. small-cap equities, has staged a remarkable comeback in 2025, driven by a confluence of factors including optimism over Federal Reserve rate cuts and a broad rotation away from overvalued mega-cap technology stocks. In August 2025 alone, the index surged 7.3%, marking its best monthly performance of the year and extending a four-month winning streak—a trend not seen since 2021 The Great Rebalancing: Small-Cap and Value Stocks Surge as …^[1].

Rotation to Value and Diversification of Market Leadership

The Russell 2000's outperformance also underscores a broader rotation toward value stocks and away from the "Magnificent Seven" tech giants.

Implications for Investors

For investors, the Russell 2000's resurgence presents both opportunities and risks. Small-cap ETFs and value-oriented strategies have gained traction, with products like the iShares Russell 2000 Value ETF (IWN) and the Vanguard Small-Cap Value Index Fund (VBR) seeing inflows History says small stocks outperform when the Fed restarts rate …^[2].
