To me the whole point of a CD is to lock in a certain rate for a specific time, but sure, playing it as you suggest is certainly an option. I recall years ago, every time rates went down by 0.25% or more, I have had my brokered CDs called-in and I believe it took a few days for the cash to end up in my core position, so that's a bit of lost interest. Generally, I just avoid callable anything these days, but I did notice the MYGAs (AKA CD annuities) often have higher rates than CDs and usually can't be called. I recently let a Gainbridge, 3 year, (online contract) annuity roll-over at 5.5%. Tax deferred and counts as income the year you cash out.
