Expanding Access to Dynamic, Fast-Growing Private Companies
Workers with 401(k)s have been unable to benefit from much of today’s growth because it sits outside of public markets.
- Today, there are half as many publicly traded companies in the U.S. as there were in the 1990s.
- More companies are going public later, choosing to stay private during their highest growth phase.
- Nearly 87% of firms with more than $100 million in revenue a year remain private.
Research from the Georgetown Center for Retirement Initiatives suggests that incorporating private investments into diversified retirement portfolios can meaningfully improve retirement outcomes.

Providing a Critical Source of Diversification
Not only are there fewer publicly traded companies today, but a small number of companies are driving a large portion of returns. That concentration leaves everyday savers more exposed to volatility.
Adding private investments to 401(k) plans can help reduce that risk because they behave differently than public stocks and bonds. Over the past decade, institutions with higher private investment allocations experienced higher returns with less volatility, according to Cambridge Associates. For everyday savers, diversification is about building more resilient retirement portfolios.
Delivering a Proven Track Record of Strong Returns
Private investments have been a cornerstone for nearly every public pension plan in America and other institutional investors, delivering strong returns and providing diversification through periods of economic uncertainty.
Expanding access would allow everyday savers with 401(k)s to enjoy many of those same benefits and build more resilient, long-term retirement portfolios.
