Vanguard Federal Money Market Fund (VMFXX)

VMFXX holds its price at exactly $1.00, with zero movement over the past month.

What is going on right now?

Nothing has changed in its price. It sat at $1.00 yesterday, last week, and last month, which is exactly how this type of fund is designed to work.

How is the business itself doing?

Vanguard's Federal Money Market Fund works like a parking spot for cash. It holds very short-term government-related items and pays you a small return, similar to how a savings account works at a bank. It currently manages about $375.6 billion.

What stands out?

That $375.6 billion pool is enormous. Reports about stress among European banks could nudge more money into U.S. government-focused funds like this one, though nothing has shifted yet.

What comes next?

The return you earn here moves with short-term interest rates set by the Federal Reserve, so the next rate decision directly changes what VMFXX pays out.
