That's the usual way people look at it. The MM's are still "high", though, and higher than CDs and treasury bonds. CD's and treasury bonds have the future "expected" rates (and their risk aversion) factored in. So, you lock into lower rates for longer terms, and hope the MM rate doesn't rise a bunch and you miss out on better gains, or if MM rates drop you feel good about your decision to switch to CDs or treasury bonds.
But, the 1 year CD and treasury rates aren't too much lower (this is subjective, of course) than the MMs, and the fed isn't talking drastic rate drops, so I don't have a whole lot of reason to feel I need to move out of VMFXX this year.
