Inferring Stock Duration Around FOMC Surprises: Estimates and Implications
Published online by Cambridge University Press: 21 December 2020
Abstract
Discount rates affect stock prices directly via the discount-rate channel or indirectly via the cash-flow channel because expected future cash-flow growth varies with the discount rate. The traditional Macaulay duration captures the effect from the discount-rate channel. I propose a novel duration measure, the effective equity duration, to capture the effects from both channels. I estimate it around unexpected policies in the federal funds rates. I find that the equity yield curve is hump-shaped because expected future cash-flow growth increases with the discount rate. The effective equity duration captures information other than monetary policy risk.
