how is volatility measured bond
One way to measure a bond's volatility is to track its spread against another bond. Basically, you will need to compare the bond's performance over time to a relatively stable bond. The most stable bonds are US Government Bonds. Start with a federal bond and track interest rate over a time period of 1 to 5 years.
Duration is another way to measure bond volatility. Duration is a measure of how much the price of a bond changes when compared to its interest rate. Bond price will change from time to time as the issuing organization evaluates the value of the bond on the market.
