A bond's price is a function of the quality (financial health) of the issuer; current interest rates; and the bond's term to maturity. A bond's yield is defined as its coupon divided by its current price If the price of a bond rises, the yield falls. If the price of a bond falls, the yield rises. A bond's yield to maturity is the total return anticipated on a bond if the bond is held until it maturity, and reflects the interest earned and capital gains or losses (the change in price from the bond's issue, usually $1,000).
All current bond prices, and historical prices back through several decades, can be accessed with the Business Center's Bloomberg terminal. Use the function keys (such as MUNI, PFD, etc.), or the help box, to search.
