Exchange-traded funds have enjoyed growth and popularity with investors and financial advisors in recent years. Thanks to their tax efficiency and often lower fees, they have been siphoning assets from their older rivals, mutual funds. But with a recent patent expiration, dozens of asset managers are gearing up to offer ETF share classes within mutual funds. Here's what advisors and their clients should know.
For years, Vanguard was the only mutual fund firm able to use ETF share classes, debuting this hybrid structure in 2001 under a patent that expired in 2023.
A number of asset management firms have applied to the Securities and Exchange Commission for exemptive relief that allows them to also offer ETF share classes. These firms believe that offering ETF share classes of their mutual funds will benefit holders of both types of shares. In some cases, companies are adding an ETF share class; in others, they are converting mutual funds to ETFs, eliminating the mutual fund.
A key motivation for many asset management firms is the popularity of ETFs compared to mutual funds.
In 2023, $510 million in assets left mutual funds, according to Morningstar. Through October 2024, an additional $300 million in assets exited mutual funds; through the same time period, ETFs added about $800 million in new assets. This trend has persisted over a number of years and lately has been fueled by the growing use of actively managed ETFs.
Vanguard’s ETF Share Classes
Vanguard has offered ETF share classes of its index mutual funds since 2001. Using its popular Total Stock Market Index fund as an example, Vanguard offers these mutual fund share classes:
The ETF share class has no minimum initial investment and generally requires that the investor purchase a single share. Some brokers even allow for the purchase of fractional shares. The ticker is VTI; the expense ratio is 0.03%, comparable to the institutional share class.
ETF Share Classes Awaiting Approval
There are about three dozen asset managers seeking exemptive relief to be able to offer an ETF share class of some of their mutual funds. Among these asset managers are PGIM, Fidelity Investments, Morgan Stanley Investment Management, BlackRock and Dimensional Fund Advisors.
