As investment vehicles continue to evolve in the financial landscape, exchange-traded funds (ETFs) have emerged as a formidable competitor, particularly in the realm of retail investing. Since their inception in the early 1990s, ETFs have drawn in approximately $10 trillion in assets. In comparison, mutual funds dominate with about $20 trillion, yet ETFs have managed to increase their market share significantly over the past decade, rising from 14% to 32% of the mutual fund total as reported by Morningstar Direct. Despite their rising popularity among individual investors, ETFs have struggled to gain traction within employer-sponsored 401(k) plans, a lucrative segment that remains largely untapped.
The 401(k) space represents a staggering $7.4 trillion and involves over 70 million participants, based on data from the Investment Company Institute (ICI). Additionally, other plans, including those for educational institutions and governmental workers, contribute another $3 trillion to this impressive pool. Nevertheless, a glaring discrepancy exists; the overwhelming majority of these assets reside in mutual funds rather than ETFs. Financial experts such as Philip Chao, a certified financial planner, have identified this as a critical juncture for ETFs—an opportunity to capture a significant portion of retirement funds that are not typically aligned with ETF offerings.
Chao describes the 401(k) market as “the final frontier” for ETFs, highlighting the vast sums of money waiting to be accessed. An essential factor for understanding this gap lies in identifying the reasons why employers continue to favor traditional mutual funds over newer structures like ETFs within these retirement plans.
According to ICI data, about 65% of 401(k) assets are invested in mutual funds. In contrast, reports from the Plan Sponsor Council of America (PSCA) suggest that ETFs account for a negligible fraction of the 401(k) market. Additionally, a PSCA study from 2022 indicates that while ETFs are sometimes utilized for sector and commodity funds, they are employed a mere 3% of the time in 401(k) plans.
A critical examination reveals several barriers to widespread adoption. One of the primary challenges is the structural hierarchy present in company-sponsored retirement plans, where investment decisions are made by employers rather than individual participants. This system can limit access to ETF options, as the choice of available funds is at the discretion of the company management.
Technology also plays a critical role in the limited acceptance of ETFs in retirement plans. Traditional retirement plan infrastructures were not constructed to facilitate the intraday trading that ETFs allow, as noted by Mariah Marquardt of Betterment for Work. Unlike mutual funds, which settle at the close of market hours, ETFs require a different operational framework to function properly within 401(k) accounts.
Furthermore, the supposed advantages of ETFs—such as tax benefits and relative trading flexibility—fail to resonate within the 401(k) context. According to David Blanchett of PGIM, the tax-deferred nature of 401(k) accounts negates the capital gains tax advantages that ETFs typically offer. Additionally, a mere 11% of 401(k) investors engaged in trades or exchanges in their accounts in 2023, as reported by Vanguard, indicating that the benefit of intraday trading is largely irrelevant for long-term retirement savers.
One aspect that plays into the reluctance to incorporate ETFs into 401(k) plans is the perception of fees. Mutual funds have a more opaque fee structure involving various classes and hidden charges that may not be immediately visible on investor statements. Chao notes that this can create a sense of financial comfort where investors feel they are not burdened by excessive costs, while ETFs, with their straightforward fees displayed in line items, can make investors uncomfortable—even if they provide a more transparent pricing structure.
This juxtaposition leads to a prevailing idea that “ignorance is bliss” for many 401(k) participants, who might prefer the familiar and seemingly simpler mutual fund structure to the detailed disclosures that come with ETFs.
As we look to the future of retirement investing, it’s clear that ETFs must navigate several hurdles to gain ground in the 401(k) market. With their distinctive structure and inherent benefits, ETFs hold considerable promise. However, addressing operational challenges, refining perceptions regarding fees, and advocating for greater access will be crucial to their acceptance in workplace retirement plans. As Philip Chao aptly puts it, the 401(k) landscape represents a significant opportunity for ETFs—one that stands to reshape the investment strategies of millions. It remains to be seen whether the industry will rise to the occasion and embrace this potential shift.
