What's a money market fund?
A money market fund is a type of fixed income mutual fund that invests only in highly liquid, short-term debt. These funds offer a low level of risk because they invest in low-risk investments like government-backed securities. You can use a money market fund to save for short-term goals such as a wedding, a down payment on a home, or an unexpected life event.

A repurchase agreement, also known as "repo," is an agreement in which a money market fund provides cash to a counterparty such as the New York Fed and receives U.S. government securities as collateral backing the transaction. The counterparty agrees to buy back the collateral at a specified time and price, implying a rate of interest for the money market fund.
The NAV is the price per share at which you buy or sell a money market mutual fund. It's calculated at the end of the trading day.
