Northern Trust (NASDAQ:NTRS | NTRS Price Prediction) is changing how many investors hold some of its biggest index funds. The asset management arm plans to convert six mutual funds representing approximately $33 billion in assets into exchange-traded funds (ETFs), according to the company’s announcement on September 28, 2026.
These are conversions of existing funds. The firm managed approximately $27 billion in ETF assets as of June 30, 2026, so these conversions would more than double that platform.
The firm expects the transitions to take place during the first quarter of 2027. The firm is announcing early so shareholders and distributors have time to evaluate the changes.

What Changes for You If You Own One of These Funds
Holders of these funds will see their shares become ETF shares. Here’s what that means in practice.
How You Buy and Sell
Mutual fund orders fill once a day at net asset value (NAV). ETF shares trade all day at a market price that can sit slightly above or below NAV, and you’ll deal with a bid-ask spread (the gap between what buyers pay and what sellers get), which is a real cost every time you trade.
How You’re Taxed
When investors cash out of a traditional mutual fund, the manager may sell securities to raise money, and any gains get passed to remaining shareholders as taxable distributions. ETFs usually handle exits differently: authorized participants exchange ETF shares for baskets of underlying securities, letting the fund avoid selling holdings and realizing gains.
ETFs have a structural tax advantage, but your result depends on your situation and account type. Inside an IRA or employer retirement plan, the difference matters far less because those accounts already shield gains from yearly taxes.
What You Can See
ETFs publish their full holdings every day, so you’ll be able to see exactly what your fund has at any time.
Your Automatic Investments
Automatic monthly contributions and dividend reinvestment set up for a mutual fund don’t always carry over smoothly to an ETF, because some brokerages don’t support fractional ETF shares, which can leave cash uninvested. Before the switch, confirm with your brokerage and plan provider how they will handle recurring purchases and reinvested dividends.
What Stays Exactly the Same
The investment strategies, the index exposure, and the management approach all carry over. If you own the mid-cap index fund for its mid-cap exposure, the new ETF is built to deliver that same exposure.
Why Fund Companies Keep Turning Mutual Funds Into ETFs
Northern Trust follows a path many fund companies have taken. Mutual-fund-to-ETF conversions have sped up since 2021, with early movers including DFA, JPMorgan, Fidelity and Guinness Atkinson. SEC Rule 6c-11, adopted in 2019, made launching ETFs easier. At approximately $33 billion, this ranks among the larger mutual-fund-to-ETF conversions of its kind.
Northern Trust has momentum in ETFs. On its July earnings call, the chief executive cited “our fifth consecutive quarter of positive flows” in ETFs. Northern Trust shares closed at $170.67 on October 5, up 26.86% year-to-date.
The next step for shareholders is the formal paperwork. Watch for updated fund filings and notices from your brokerage confirming the exact conversion date and how your account will be handled.
