The "Great Rotation": Capital Shifts from Mega-Cap Growth to Small-Cap and Value (May 2026)
A profound structural transformation is reshaping global equity markets in May 2026. The "Great Rotation"—characterized by capital migrating away from elite, asset-light US mega-cap technology companies toward small-cap, value, and "old economy" infrastructure stocks—has accelerated.
This rotation is driven by a combination of historical valuation extremes, broadening corporate earnings, and growing investor scrutiny of the return on investment (ROI) for artificial intelligence capital expenditures.
The Valuation Gap and the "Coiled Spring"
By early 2026, the valuation discrepancy between small-cap stocks and the broader S&P 500 had reached a 25-year extreme:
- Forward Multiples: The Russell 2000 Index traded at a modest 18.0x forward earnings, compared to a steep 22.0x+ multiple for the S&P 500.
- The Shiller P/E: The inflation-adjusted 10-year Shiller P/E ratio for the S&P 500 surpassed 40, its highest level since the peak of the dot-com boom, historically signaling a high probability of a market correction or flat returns for large-cap indices.
- Earnings Strength: Small-cap fundamentals have provided a strong foundation for this shift. Russell 2000 components posted a robust 65% earnings beat rate in Q4 2025.
- Growth Outlook: Consensus estimates for the full year 2026 project a 19% year-over-year earnings growth for the Russell 2000, significantly outpacing the 12.5% projected for the cap-weighted S&P 500.
This combination of low valuation and superior projected growth created a "coiled spring" effect. In early 2026, the Russell 2000 surged over 7%, while the cap-weighted S&P 500 remained flat, signaling the start of a broadening market.
Institutional Rebalancing: Trimming the Giants
Multi-billion dollar institutional managers are actively executing this rotation. For example, recent regulatory filings from Kovitz Investment Group Partners reveal significant trims in highly valued holdings to fund reallocations into small-cap, value, and infrastructure segments:
- Mega-Cap Valuations: Investors are questioning the massive valuations of giants like Apple (AAPL), which reached a $4.00 trillion market capitalization trading at a P/E of 34.08x, and Broadcom (AVGO), commanding a P/E of 66.60x.
- Trimming Positions: Kovitz trimmed its stake in Advanced Micro Devices (AMD) by 2.1% (selling 37,819 shares, though retaining a $292 million position), slashed its Johnson & Johnson (JNJ) holding by 45% (selling 201,160 shares), and reduced Dollar Tree (DLTR) by 10.8%.
Where is the Capital Flowing?
The capital exiting mega-cap tech is being redeployed into high-conviction, valuation-supported areas:
- Old Economy and Data Center Infrastructure: Companies deeply tied to physical infrastructure and domestic energy efficiency are major beneficiaries. Examples include Willdan Group (WLDN), which provides energy-efficient engineering for AI data centers, and Gorman-Rupp (GRC).
- Specialized Biotech: Small-cap biotech companies such as Dianthus Therapeutics (DNTH) and Ligand Pharmaceuticals (LGND) are attracting capital, aided by the reversal of 2017-era R&D tax rules that make their pipelines highly valuable.
- AI Infrastructure Pivots: Some energy-focused small-caps, like CleanSpark (CLSK), are actively pivoting their operations toward high-performance computing (HPC) and AI infrastructure colocation, capturing the AI tailwind at a fraction of mega-cap valuations.
This structural rotation represents a shift from passive index-tracking toward active stock selection, where valuation, balance sheet strength, and tangible assets are rewarded over speculative tech growth.
