What Is a Unit Investment Trust (UIT)? A unit investment trust (UIT) is an investment company that offers a fixed portfolio, generally of stocks and bonds, as redeemable units to investors for a specific period of time. It is designed to provide capital appreciation and/or dividend income. Unit investment trusts, along with mutual funds and closed-end funds, are defined as investment companies.
KEY TAKEAWAYS A unit investment trust (UIT) is a U.S. financial company that buys or holds a group of securities, such as stocks or bonds, and makes them available to investors as redeemable units. UITS are similar to both open-ended and closed-end mutual funds in that they all consist of collective investments in which many investors combine their funds to be managed by a portfolio manager. Like open-ended mutual funds, UITs are bought and sold directly from the company that issues them, although sometimes they can be bought on the secondary market; like closed-end funds, UITs are issued via an initial public offering (IPO). Unlike mutual funds, UITs have a stated expiration date based on what investments are held in its portfolio; when the portfolio terminates, investors get their cut of the UIT's net assets. Also unlike mutual funds, UITs aren't actively-traded, meaning securities aren't bought or sold unless there's a change in the underlying investment, such as a corporate merger or bankruptcy.
