A cliche in investing, it rings true on many scales but is hard to act on. For
example, we know bond rates have reached unseen levels since the Great
Recession. They have to come down, but when? They are no where near historical
records yet and can go higher as the Fed has to appear tough on inflation which,
despite what statisticians say, hasn't seemed to abate. How many would commit to
5%, watch the dollar crumble and bond prices plummet year after year, and hold
on to maturity? Bad timing would guarantee a lose-lose. The advice seems both
sound and useless.
