whats a good rate and how do i calculate the interest rate

Say I was to open a CD account with 0 in it for 9 months with a Interest rate of 4.72% and it was compounded at Maturity would that mean I would only be making like off my CD account?

I just opened a cd an I want to figure out simple interest. Which do I use Interest rate or Yield?
My yield is higher than my interest rate.

Don’t know if that’s a newbie question but is there? I have a theory strategy in my head of keeping most of my invest-able assets in stocks when CD rates are low then selling stocks and buying CD’s when the interest rate is above 5%. This allows me to have cash on hand when a stock market crashes… allowing me to invest heavily when prices are attractive.
Moneyman – So does my strategy make any sense?
