- Equities dominate 71.5% of 401(k) balances, but Q1 2025 volatility triggered 73% equity outflows as investors shifted to safer fixed income assets.

- Younger investors increasingly favor target date funds (32% of balances), while older investors defy norms by boosting equity exposure to offset savings gaps.

- The 2025 executive order expanding alternative assets in 401(k)s accelerates diversification into private equity and real estate, despite liquidity and fee risks.

- Over-reliance on equities risks long-term sustainability, as 20% market corrections could erase 30% of portfolios in low-growth, high-inflation environments.

- Strategic recommendations emphasize balancing equities with alternatives, dynamic rebalancing, and liquidity reserves to build resilient retirement portfolios amid regulatory and market shifts.

The average equity allocation in 401(k) portfolios has long been a cornerstone of retirement planning, but recent market dynamics are exposing the fragility of this strategy. As of mid-2025, equities still dominate 71.5% of 401(k) balances, with large U.S. equity funds holding 29% of total assets. However, this figure masks a critical trend: investors are increasingly rebalancing portfolios in response to volatility, often at the expense of long-term sustainability.

The Volatility Conundrum

The S&P 500's -4.27% return in Q1 2025 and the Russell 2000's -6.81% drop underscored the risks of overexposure to equities. During this period, 73% of outflows from 401(k)s were tied to equities, with target date funds and large U.S. equity funds bearing the brunt. Conversely, fixed income funds—particularly stable value and bond funds—saw 33% of inflows. This shift reflects a flight to safety, but it also raises a critical question: Is short-term risk mitigation undermining long-term growth?

Age and Allocation: A Shifting Paradigm

Equity allocations vary sharply by age, but even younger investors are showing caution. Those in their 20s and 30s maintain 41-44% in U.S. stocks, yet this group is increasingly opting for default options like target date funds, which now hold 32% of 401(k) balances. Meanwhile, older investors—traditionally more conservative—are defying norms. Between 2019 and 2024, 50% of those aged 50+ increased equity exposure, seeking to offset savings shortfalls. This inversion of traditional glide-path strategies highlights a growing disconnect between age-based risk tolerance and actual behavior.

The Regulatory Tailwind: Alternatives on the Horizon

A seismic shift is underway. The August 2025 executive order, which mandates expanded access to alternative assets in 401(k)s, is accelerating diversification. Private equity, real estate, and even cryptocurrencies are now being integrated into retirement portfolios via institutional structures. For example, Empower's zero-fee S&P 500 Index Separate Account and its private market offerings exemplify this trend. While these alternatives promise uncorrelated returns, they also introduce liquidity constraints and higher fees—risks that must be carefully weighed.

The Long-Term Sustainability Dilemma

Retirement portfolios are not just about surviving market downturns; they're about outliving them. Over-reliance on equities, while historically rewarding, becomes perilous in a low-growth, high-inflation environment. Consider this: if a 60-year-old investor holds 36.8% in U.S. stocks and 8.4% in international equities, a 20% market correction could erode nearly a third of their portfolio. Rebuilding that capital in a low-interest-rate world is far more challenging than in the past.

Strategic Recommendations

  1. Diversify Beyond Equities: Allocate 20-30% of portfolios to alternatives like private credit or real estate, which offer income and inflation protection.
  2. Leverage Target Date Funds with Caution: While these funds simplify asset allocation, they often underperform custom strategies. Review their glide paths and consider rebalancing.
  3. Adopt Dynamic Rebalancing: Use market volatility as an opportunity to buy undervalued assets. For instance, the S&P 500's Q1 2025 dip could be a buying window for long-term investors.
  4. Prioritize Liquidity: Ensure 10-15% of assets are in cash or money market funds to avoid forced sales during downturns.

Conclusion

The 401(k) landscape is evolving rapidly, driven by regulatory shifts and investor demand for alternatives. While equities remain a vital component of retirement portfolios, their dominance in volatile markets risks undermining long-term sustainability. A balanced approach—combining equities with alternatives, fixed income, and liquidity—offers a more resilient path to retirement. As the Trump administration's executive order reshapes the playing field, investors must act swiftly to align their strategies with this new reality. The goal isn't to chase returns but to build portfolios that endure.
