modified duration - Investment & Finance Definition
A measure of the Macaulay Duration adjusted to help estimate a bond’s price volatility. Calculating modified duration gives an estimate of how bond prices would change if interest rates changed a small amount. Measuring the effect that large changes in interest rates would have on bond prices requires examining a bond’s convexity, or the measure of the curvature of the price-yield relationship.Webster's New World Finance and Investment Dictionary Copyright © 2010 by Wiley Publishing, Inc., Indianapolis, Indiana.
