Yield spread

Yield spread is a way to compare how much money two different investments will make. It is calculated by subtracting the interest rate or "yield" of one investment from the interest rate or "yield" of another investment. For example, if one investment has a yield of 3% and another investment has a yield of 5%, the yield spread is 2%. That means the second investment would make 2% more than the first one.
