In an unpredictable economy, cash is king.
Over the past year and a half, money market funds have exploded in popularity. In 2023, almost $970 billion flowed into the funds, according to Morningstar Direct. And just in the first three months of 2024, investors have already poured in another $17 billion.

Not only that, but the high yields that make the funds so attractive can be ephemeral.
"The biggest disadvantage that I see comes from the change in yield," Guajardo said. "Money market funds offer no guaranteed yield and can change in an instant."
But in the context of a well balanced, diverse portfolio, most wealth managers agree money market funds can serve a useful purpose, especially in today's unpredictable environment.
