In this edition of The Motley Fool's "Ask a Fool" series, Motley Fool One analyst Jason Moser takes a question from a reader who asks: "Where would a Fool keep emergency money in a time of low interest rates?" Jason talks about how investors need to view investment dollars and emergency dollars separately. An investor's priority with emergency funds is not yield; it's protection. The "yield" in this case is peace of mind knowing that your emergency funds are there when you need them.
