UITFs and Mutual Funds are both investment vehicles where you join other investors and companies to pool a fund, which will be handled by a professional fund manager. This fund will be invested in a diversified basket of stocks, bonds, and other similar funds. Investing in UITFs buys you units in the fund while investing in Mutual Funds buys you shares. In addition, most Mutual Funds charge a front-end load, which can be as much as 2% of the initial investment, while UITFs typically do not.
