The gobbledygook basically means, “I think bonds are wandering around their peak price; make your investments so that you will profit as they fall.”
There is no such thing as “cash” in my 401K, even the “stable value fund” is based on bonds, like all the rest of the stuff in it. Sigh.
I sense a large other shoe which will drop soon, but I believe “they” will make every effort to keep it from dropping before the Christmas shopping season. They can’t sanely believe they can keep it from dropping forever.
