Duration Matching as a Risk Management Tool: A Case Study of Apple and Netflix Corporate Bonds

This paper examines how duration matching can be employed as a practical, data-driven strategy to mitigate interest rate risk in corporate debt portfolios. Focusing on real-market corporate bonds issued by Apple Inc. and Netflix Inc., it demonstrates the steps for identifying optimal bond allocations that align a firm’s asset duration with its liability duration. The research underscores the importance of accurately measuring interest rate sensitivity through Macaulay and Modified Duration, then constructing a portfolio whose overall duration closely approximates the target liability’s duration. By methodically analyzing each bond’s yield, coupon structure, price, and resulting duration, the paper shows how to hedge against rate fluctuations and stabilize the total market value of an organization’s future debt obligations. The findings carry broad implications for both corporate and institutional investors, offering a replicable framework for duration-based risk management. It also highlights how duration matching connects theoretical models with real-world fixed-income strategy under changing market conditions.
