uration is a concept that has received wide i. B attention in the management of fixed-income portfolios, as well as in the asset-liability management interface applicable to many financial institutions. ’ Duration has received much less attention as an equit,y management concept. Nevertheless, the majority of equity portfolio managers realize that, at least in the last cycle, they have been ”playing the bond market” to a large degree that rising and falling interest rabes have been a major determinant of changes in stock prices. Duration analysis or evaluation of a stock‘s sensitivity to changes in the underlying discount rate is more complicated for stocks than it is for riskless bond portfolios. The resulting measure of a stock’s duration may be a proxy for “longness,” but we can also express it as a sensitivity of PIE change to discount rate change. Moreover, changes in the equity market discount rate are influenced by unexpected movements in interest rates as well as by changes in the market’s perception of the risk of holding equities. Equity duration is best understood when we put it into a valuation context and then contrast it to classic bond valuation. The generic valuation model following, with our interpretation of how an analyst should assess valuation parameters, provides a framework for discussing equity duration in the light of other factors that influence security pricing. Most valuation models, regardless of how elaborate, are related to the intrinsic value notions applied
