Public DATs Face Decline as Volatility Surges

The investment landscape in late 2025 has been defined by a perfect storm of rising volatility, fragmented Federal Reserve policy, and a mass migration of capital toward defensive assets. As the CBOE Volatility Index (VIX) fluctuated between 15.41 and 17.28 in December 2025 according to data, markets grappled with the dual forces of economic uncertainty and policy ambiguity. Meanwhile, public direct indexing platforms (DATs)-once hailed as a disruptive force in passive investing-now face headwinds as investors pivot to safer havens. This shift underscores a broader recalibration of risk preferences in a world where traditional correlations are breaking down and Fed signals are increasingly contradictory.

The Fed's Fragmented Policy and Market Volatility

The Federal Reserve's October 2025 FOMC minutes revealed a stark divergence in policy outlooks. While officials anticipated two rate cuts by year-end, uncertainty lingered over the December meeting, with debates intensifying about the risks of tightening labor markets and inflation persistence. Compounding this, the Fed's consideration to halt the SOMA portfolio runoff-a move aimed at stabilizing repo markets-highlighted its growing concern over systemic volatility. This policy fragmentation has created a "fog of uncertainty," as investors struggle to parse whether the Fed is leaning toward easing or tightening.

The result? A market environment where volatility is not just a backdrop but a defining feature. The VIX's moderate readings mask deeper turbulence: sectors like technology and consumer discretionary swung wildly, creating tax-loss harvesting opportunities that exceeded long-term averages by more than double. For investors, this volatility has become a double-edged sword-offering tactical advantages for tax optimization while amplifying the risks of overexposure to high-conviction, market-linked strategies.

Defensive Positioning: The New Normal

As the Fed's policy signals diverged, investors increasingly turned to defensive positioning. According to a 2025 Spring Investment Directions report, the traditional negative correlation between equities and bonds has weakened, forcing a reevaluation of diversification strategies. Defensive equities, low-volatility portfolios, and uncorrelated assets like gold, inflation-linked bonds, and infrastructure investments gained traction. This shift was further accelerated by macroeconomic headwinds, including geopolitical tensions, trade policy uncertainties, and a slowing global growth outlook.

Public DATs, which rely on market exposure and tax-loss harvesting, found themselves at a crossroads. While platforms like Public offered low-cost access to direct indexing and customizable portfolios, their appeal waned as investors prioritized safety over tax efficiency. The ability to exclude specific stocks or overweight sectors-a key DAT advantage-became less relevant in a market where broad-based risk-off moves dominated.

DATs Under Pressure: AUM Trends and Structural Challenges

The AUM trajectory of public DATs in 2025 tells a story of mixed fortunes. By Q1 2025, DAT assets had dipped to $864.3 billion from a peak of $900 billion in late 2024, signaling a slowdown in growth. This decline was exacerbated by structural challenges: while tax-loss harvesting remained a draw during volatile periods, its benefits were limited to taxable accounts, leaving a gap in utility for retirement-focused investors.

Moreover, the Fed's policy uncertainty and the U.S. government shutdown in late 2025 disrupted data flows, creating a "blackout" that muddied investment decisions. Without reliable economic indicators, investors leaned into defensive allocations, further straining DATs that thrive in high-volatility, high-liquidity environments. Even as tax-loss harvesting potential surged-with loss capture rates exceeding 20% in diversified strategies-the broader market's risk-off sentiment diluted demand for market-linked exposure.

Implications for High-Risk, High-Conviction Strategies

The decline of public DATs reflects a broader trend: the erosion of appetite for high-conviction, market-linked strategies. In a fragmented Fed policy landscape, investors are prioritizing resilience over returns. Active ETFs and liquid alternatives, which offer uncorrelated returns and downside protection, are gaining ground. Meanwhile, infrastructure and private credit-sectors with inflation-hedging properties-are attracting inflows as traditional asset classes falter.

For DATs, the path forward hinges on innovation. Platforms must evolve beyond tax-loss harvesting to address the full spectrum of investor needs, including ESG customization, sector tilts, and integration with alternative assets according to market analysis. However, in a world where defensive positioning is king, the question remains: can DATs adapt quickly enough to retain relevance in a risk-averse market?

Conclusion

The 2025 market environment has exposed the fragility of public DATs in the face of volatility and policy fragmentation. As the Fed's signals diverge and investors retreat to safer assets, the appeal of market-linked strategies is waning. While tax-loss harvesting and customization remain valuable tools, they are no longer sufficient to counteract the broader shift toward defensive positioning. For DATs, the challenge is clear: innovate or risk obsolescence in a landscape where survival demands more than just tactical efficiency.
